Ischia earthquake

The day calamity and chaos came to Casamicciola

Around 3,000 people are thought to have been killed and many more injured on this day in 1883 after a devastating earthquake shook the island of Ischia in the Gulf of Naples.

Although the earthquake was officially classified as moderate, it caused extreme ground shaking, which led to the collapse of about 80 per cent of the buildings in the comune of Casamicciola Terme, a resort on the northern side of the island.

Most of the houses, hotels, and churches in the town collapsed. There were more than 1,700 fatalities in Casamicciola alone.

The philosopher Benedetto Croce was on holiday on the island at the time and both his parents and his only sister were killed in the earthquake. He was trapped under the rubble for two nights until he was able to be rescued, and it was discovered that he had a broken leg and arm.

His daughter later said that he suffered nightmares about his experience afterwards and that he never returned to Ischia. 

But many people who were trapped under the wreckage of the buildings were not rescued and eventually died. 


The earthquake occurred at 20.25 local time and had a moment magnitude of between 4.2 and 5.5. Though this was considered moderate, the ground shaking was judged to be extreme on the Modified Mercalli intensity scale. It is thought that between 2,313 and 3,100 people died as a result.

The island of Ischia lies within the circular area known as the Phlegraean Fields, a volcanic caldera consisting of 24 craters, most of which are submerged under the Bay of Naples.

The island’s highest point, Monte Epomeo, is a geological horst, a block of volcanic material that has been deposited by eruptions.

Since the middle of the 18th century, there have been records of earthquakes affecting the island. 

In 1762, the architect Luigi Vanvitelli said he had experienced two successive shocks on the island, and in 1796, seven people died and 50 buildings were destroyed, after an earthquake.

In 1828, a violent tremor destroyed buildings in Casamicciola and at least 29 people died, including people who had been attending a church service. An earthquake in 1867 was experienced by the Norwegian playwright Henrik Ibsen, while he was staying there.

In March 1881, an earthquake caused 127 deaths and the collapse of about 300 buildings there. During the July 1883 quake, structures that had been damaged in 1881 but had not been repaired, collapsed completely.

In 1883, nearly half of the population of Casamicciola were killed and there were also deaths in Lacco Ameno, Forio, Barano d’Ischia, and Serrare Fontana.

Many Romans and Neapolitans were on holiday on the island at the time of the earthquake and a lot were attending a performance at the theatre. Large gaps appeared in the walls of the theatre and some theatregoers were able to escape through them.

People who were able to flee from the devastation made their way to the sea and were taken to Naples by boats to recover, and give an account of what had happened on the island.

Soldiers were sent to Ischia to dig for survivors but were unable to reach many of the victims, who died before they could be brought out of the wreckage. Steamers were deployed to go back and forth taking injured survivors to hospital in Naples 

Newspapers came out in Rome with black mourning borders on July 30 to mark the event. The King and Queen of Italy - Umberto I and Queen Margherita - and the Pope, Leo XIII, donated money towards a national fund that was started for the relief of the earthquake victims.

As a result of the 1883 Ischia earthquake, the Italian government issued  codes for antiseismic prevention

Even now, Italians will sometimes say: “Faccio una Casamicciola,” which literally means ‘I make a Casamicciola,’ when they are describing a state of calamity, chaos, and helplessness.

According to the American TV host and actor, Jimmy Kimmel, whose mother’s ancestors were from Ischia, only two of them survived the 1883 earthquake, later deciding to emigrate to the United States.

The artist Rodolfo Morgari depicted the aftermath of the 1883 earthquake in a painting entitled, Episode after 1883 earthquake at Casamicciola, which was exhibited in Turin in 1884.

Travel tip:

Ischia is a beautiful island, just  off the coasts of Sorrento and Naples, with many good beaches for holidaymakers. It has an area of some 47 square  kilometres, rising to a height of 789 m (2,589 ft) at the peak of Monte Epomeo. The vineyards surrounding Monte Epomeo produce excellent wine that is served in the island’s restaurants. The hot mineral springs on the island have been used since Roman times as a cure for ailments and are still recommended for people suffering from rheumatism and arthritis today. An entire circuit of the island’s 34km (21 miles) of coastline on one of the local buses will take about two and a half hours. Ischia is also the name of the island’s main town, the other municipalities being Barano d'Ischia, Casamicciola Terme, Forio, Lacco Ameno and Serrara Fontana. Notable sights include the Aragonese Castle (Castello Aragonese), which was built on a rock near the island in 474 BC, by Hiero I of Syracuse. Nowadays, it is connected to the town of Ischia by a stone causeway.

Travel tip:

Casamicciola is the oldest spa town on the island of Ischia and is thought to have once been the site of a Greek settlement. It is home to the hottest spring on the island, Terme Rita, which comes out of the ground at 180F and is said to contain large quantities of Iodine. One of the few hotels that remain standing from before the 1883 earthquake is Terme Manzi Hotel and Spa, which was founded in 1860. After the earthquake, the town was rebuilt and the Art Nouveau architecture lining the waterfront promenade dates from the early 20th century. The town continues to suffer sporadic earth movements linked to activity in the Phlegraean Fields caldera. As recently as August, 2017, it was hit by a 4.3 magnitude earthquake, resulting in the deaths of two people. Casamicciola has a pretty port and marina, which is often populated by expensive yachts. It is also an arrival and departure point for hydrofoils and ferries to and from Naples on the mainland.

Irpinia earthquake

A day that saw whole towns reduced to rubble in southern Italy

Aerial pictures show the remains of 
the village of Castelnuovo di Conza
An earthquake that has been described as ‘the worst catastrophe in the history of the Italian republic’ shook Campania and parts of Basilicata and Puglia on this day in 1980.

The earthquake, which takes its name from the geographical area of Campania known as Irpinia, had a moment magnitude of 6.9 and left 2,483 people dead, about 7,700 injured, and more than 250,000 homeless. The first shock lasted for a little more than a minute, but it was to change the lives forever of the residents in the worst hit towns and villages in the region.

The earthquake struck at 18:34 local time and after 70 seconds of shaking there were many aftershocks. Waves from it were felt as far away as Sicily and the Po Valley.

The village of Castelnuovo di Conza, in the province of Salerno, was at the centre of the blast and was virtually destroyed. Of the 1500 inhabitants, about 500 died or were injured after being trapped in the rubble of their homes, including both local policemen. About 80 per cent of the buildings were either destroyed, or partially collapsed, leaving many people homeless.

It was left to the local children and old people to dig for any survivors and the Mayor of the village later said they had been forced to wait for three days for help to arrive from outside the area. 

In nearby Sant’Angelo dei Lombardi, in the province of Avellino, 300 people were killed, including 27 children in an orphanage. Many historical buildings were left in ruins and some of them were never rebuilt. 

Scenes of devastation were witnessed in many towns and villages across the Irpinia area

In Naples, a ten-storey apartment building collapsed as a result of the tremor. Many buildings suffered extensive structural damage and had to be propped up to make them safe afterwards, leading to years of disruption to the lives of the people living there.

In Balvano in the province of Potenza in Basilicata, 100 people were killed when a mediaeval church collapsed during a service. Many of them were children and teenagers and the disaster effectively wiped out an entire generation of the local people.

The University of Basilicata was later built in Potenza on a site that had been flattened by the earthquake. It was seen as an attempt to persuade young people to stay in the area rather than moving north or emigrating to another country.  

Many landslides were triggered and rail traffic throughout Italy came to a complete standstill. The terrible situation was made worse by people trying to leave the affected areas in such large numbers that the roads became blocked.

On November 26, Italian president Sandro Pertini addressed the nation in a televised broadcast. He condemned the delays in rescuing people from the ruins after the earthquake and the failures that had been revealed in state intervention in the worst affected areas.

As a result, Extraordinary Commissioner Giuseppe Zamberletti was appointed to coordinate rescue efforts and to communicate with the local mayors. In 1982, Zamberletti was appointed Minister for Civil Protection Co-ordination and a few months later the Department of Civil Protection was established in Italy.

When the 40th anniversary of the earthquake disaster was commemorated in Italy in 2020, some of the reconstruction work in the worst affected areas had still not been finished.

Although the Italian Government were said to have spent 59 trillion lire, and West Germany sent 32 million dollars and the US 70 million dollars to help, it is believed subsequently that some of the funds were misappropriated by Italian politicians and by the Camorra, who subsequently became involved in the construction industry.

On average, a significant earthquake happens every four years in Italy. The most recent was an earthquake of 5.1 moment magnitude in 2023 in Tuscany, when one person died and there was severe damage in some areas.

In 1976, more than 900 people died after an earthquake of 6.5 moment magnitude in Friuli, and in 1857, 10,000 people died after an earthquake of 7.0 moment magnitude in Basilicata.

If the Irpinia earthquake is the worst since the Republic of Italy was established in 1946, the most devastating in Italy’s history, at least in terms of reliable estimates of deaths, occurred in 1908 with its epicentre below the Straits of Messina. It caused catastrophic damage to the cities of Messina and Reggio Calabria with at least 75,000 and perhaps as many as 200,000 killed, the larger figure based on comparison of census data collected before and after the disaster.

Sant’ Angelo dei Lombardi is a town in the province of Avellino in Campania. It is situated on a hilltop and has a cathedral and a Lombard castle. The Benedictine Abbey of San Guglielmo al Goleto is nearby. A famous former resident of the town is the Italian-American actor and businessman Charles A Gargano, who was born in the town in 1934. He was the US Ambassador to Trinidad and Tobago during the presidencies of Ronald Reagan and George H W Bush. After the earthquake the Lombard castle was restored to its original mediaeval structure and is today home to an archive and museum.

Travel tip:

The town of Avellino is the capital of the province of Avellino and an important centre on the road from Salerno to Benevento in Campania. It has its origins in the ancient Roman settlement, Abellinum, although the present town was founded by the Lombards and ruled at different times by the Byzantines, Normans, Swabians, Angevin, Aragonese, the Viceroy of Spain, the Austrians and the Bourbons. The 1980 Irpinia earthquake represented a turning point for the town and province because afterwards money flowed in for investment in the infrastructure. There are now many businesses in the area, such as FMA, who produce Fiat engines for car manufacturers. But the production of tobacco, wine and hazelnuts is still important to the local economy. Avellino has a cathedral, dedicated to Santa Maria Assunta, that was built in the 12th century with a neoclassical facade added in 1891.

The L’Aquila Earthquake

Shock measuring 6.3 magnitude killed more than 300

Scenes of devastation confronted rescue workers after the quake

The central Italy region of Abruzzo suffered a major disaster on this day in 2009 when an earthquake with a magnitude of 6.3 caused extensive damage and considerable loss of life in the city of L’Aquila and surrounding villages.

The main shock struck at 3.32am, when many of the victims would have been asleep, although there had been two smaller tremors the day before in an area with a long history of seismic turbulence, giving rise to speculation that a major quake was imminent.

The epicentre was only a little outside L’Aquila, a city with a population of about 70,000, damaging up to 11,000 buildings in the 13th century city.  A total of 309 people lost their lives and such was the scale of devastation that up to 65,000 people were left homeless in the city and neighbouring villages.

It was the deadliest earthquake to hit Italy since the Irpinia quake in Campania killed almost 2,500 people in 1980.

The dead in L’Aquila, a university city, included 55 students killed when their halls of residence collapsed.  The 309 victims were of 11 different nationalities, including Italians.  The main shock was felt 92 km (57 miles) away in the Italian capital, Rome.

Many of L'Aquila's medieval buildings were badly damaged, including the Basilica of Saint Bernardino of Siena, the city’s largest Renaissance church, and the Basilica di Santa Maria di Collemaggio, while the dome of the 18th-century church of Anime Sante in Piazza Duomo collapsed. Porta Napoli, the oldest gate to the city, was completely destroyed.

The collapse of the cupola of the 18th-century Baroque church of St Augustine - previously destroyed in a 1703 earthquake - damaged L'Aquila's state archives. 

But it was not only the city’s historical centre that suffered. Many of L'Aquila's modern buildings - even those thought to be earthquake-proof - were not able to withstand the shaking, including a dormitory at the University of L'Aquila that collapsed, and a new wing of the city’s main hospital, built only nine years earlier.  Shoddy construction was blamed, leaving the city much more vulnerable than it should have been, in the opinion of some experts.

Yet those held to account in the inquiries that followed were not building contractors but six scientists and a government official - members of a government commission for risk assessment - who were placed on trial for manslaughter on the grounds that they had not properly communicated the increased risk following the smaller tremors that preceded the 6 April quake. 

In October 2012,  a court found that the seven individuals were indeed guilty of manslaughter and each was handed a six-year prison sentence, although those convictions were overturned on appeal two years later.

Of the vast number of residents left homeless, some 40,000 people were accommodated in tented camps and a further 10,000 were housed in hotels on the coast. 

Prime minister Silvio Berlusconi pledged to rehouse all of the homeless and provide ample funds to rebuild the city, yet reconstruction work was slow, mired in political wrangling, bureaucracy and corruption.  The tented camps remained in place for far longer than planned and even 10 years on, some 2,000 families were still living in prefabricated, temporary accommodation.

Many of the damaged houses in the historic centre of the city are still unrepaired yet some residents moved back into them anyway. Parts of the centre are beginning to look as they did before the quake, after meticulously reconstruction of many historic buildings, although others remain clad in scaffolding and some areas still resemble buildings sites, with cranes towering above the rooftops.

The capital of the Abruzzo region, L’Aquila was built in the 13th century on a hill within the valley of the Aterno river. Its construction was started by Frederick II, Holy Roman Emperor, and completed by his son, Conrad IV of Germany. It was destroyed by Conrad’s brother, Manfred in 1259, but rebuilt by Charles I of Anjou, who surrounded it with walls.  Many of the buildings that attracted visitors to the city before 2009 have been restored, including the 12th century Basilica di Santa Maria di Collemaggio, with its distinctive exterior of alternating pink and white stone blocks, and the 15th century Basilica of San Bernardino, which reopened in 2015 after six years of restoration work that cost around €40 million.

Travel tip:

Apart from its religious buildings, L’Aquila is attractive for its maze of narrow streets, lined with Baroque and Renaissance buildings, and its elegant squares. As home to the University of L'Aquila, it has a lively atmosphere and many cultural attractions, including a symphony orchestra, a fine-arts academy, a state conservatory, a film institute and a repertory theatre. Situated in a valley in the Apennines in the shadow of the Gran Sasso massif, it is also close to a number of ski resorts.

1783 Calabria Earthquakes

Series of powerful tremors killed at least 35,000


The Calabrian peninsula of southwest Italy was waking up to the unfolding horror of a sequence of five deadly earthquakes on this day in 1783.

A major tremor destroyed the town of Oppido Mamertina in what is now the province of Reggio Calabria on 5 February, killing almost 1,200 residents, followed by another just after midnight on 6 February, setting off a tsunami that claimed still more lives.

The effects of the first quake  - which has been classified at an estimated 7.0 on the Richter magnitude scale - were felt over a much wider area, however, with countless land and rockslides.  The whole of the island of Sicily is said to have shaken.

In total, it is thought some 180 villages were effectively destroyed, with far more buildings reduced to rubble than remained standing. The city of Messina, on the northeast tip of Sicily, was seriously hit and many casualties were reported there also.

The city’s medieval Duomo was badly damaged, while a tsunami caused the walls of the harbour to collapse.

This first shock was thought to have claimed in the region of 25,000 lives across the large area affected as buildings ill-equipped to withstand such violent shaking, strong enough to knock people off their feet, simply collapsed.

Only a few hours later, just after midnight on 6 February a second major tremor occurred closer to Messina, this time put at a magnitude of 6.2. This caused a substantial rockslide into the sea near the coastal town of Scilla on the Italian mainland, which in turn set off a tsunami.  Many residents in Scilla, fearful of their homes collapsing after the 5 February quake, had taken refuge on the beach only to be swept away by the giant wave. It is reckoned around 1,500 died in Scilla.

Further up the peninsula, in the area of the Serre Mountains, about 40km (25 miles) from the first quake, a third one took place, more powerful than the second at 6.6 magnitude, at approximately 1.10pm on 7 February, flattening a string of villages between the towns of Acquaro and Soriano Calabro. Again, there were hundreds of casualties.

A period of less violent shocks followed until, on 1 March, another significant quake, put at magnitude 5.9, struck near the town of Filadelfia, about 30km (19 miles) south of Lamezia Terme. Although it took place some 100km (62 miles) northwest of Scilla and the seat of the first tremors, it was later determined to have been part of the same seismic sequence.

Damage and casualties this time were light, but that could not be said of the fifth major event, in the space of just over seven weeks, that struck on 28 March, just a few kilometres from Filadelfia, between the towns of Girifalco and Borgia. This tremor has been recorded at 7.0 magnitude, just as powerful as the first, with many villages destroyed and a further large number of residents killed.

The total number of deaths resulting from the series of earthquakes is put at 35,000 at least, although some estimates point to a figure nearer 50,000. Either way, it is one of the four deadliest seismic events in Italian history in which estimates of casualty numbers are available.

Modern science knows that the cause of earthquakes and other seismic activity in Sicily and southern Italy is caused by the collision of the African and Eurasian plates - two of the seven largest tectonic plates that make up the surface of the earth.

In the 18th century, however, there were different explanations, including one theory that there were ‘fire channels’ inside the earth, of which volcanoes were the manifestation on the surface, and that chemical reactions between gas, water and metal elements in subterranean voids were the cause of earthquakes and eruptions.

This seemed to be supported by another phenomenon that occurred at around the same time in the form of a sulfuric fog that covered much of Europe in the summer of 1783, which scientists thought was due to gas released by the Calabrian quakes although contemporary studies suggest the two things were not connected.

It is thought, instead, that the fog was the result of sulfuric gases released by a volcanic eruption in Iceland of which mainland Europeans had no knowledge.

Travel tip:

The resort town of Scilla on the north-facing Calabrian coast, situated about 23km (14 miles) north of the city of Reggio Calabria, grew up around a picturesque fishing village sheltered by cliffs and a rocky spur, atop which sits the Castello Ruffo, originally a sixth-century fortification but which has been destroyed and rebuilt a number of times.  Beneath is the sandy beach of Marina Grande, now lined with hotels. The main part of the expanded town sits above the cliffs on a plateau. On the other side of the promontory is the less developed village of Chianalea, where houses cling to the water’s edge along a single, cobbled thoroughfare.

Travel tip:

Messina, the Sicilian city separated from mainland Italy by the Strait of Messina, is the third largest city on the island and home to a large Greek-speaking community. The 12th century Duomo - the cathedral of Santa Maria Assunta - has a bell tower which houses one of the largest astronomical clocks in the world, built in 1933. Originally built by the Normans, the cathedral, which still contains the remains of King Conrad, ruler of Germany and Sicily in the 13th century, suffered much damage in 1783 and then had to be almost entirely rebuilt following the massive earthquake that struck in 1908, and again in 1943, after a fire triggered by Allied bombings.

Giuseppe Mercalli - seismologist

Giuseppe Mercalli became southern Europe's biggest authority on earthquakes and volcanic activity
Giuseppe Mercalli became southern Europe's biggest
authority on earthquakes and volcanic activity

Scientist who invented Mercalli Scale died in fire


The seismologist and volcanologist Giuseppe Mercalli, who at the time of his death was director of the Vesuvius Observatory, died in a fire at his home in Naples on this day in 1914.

The initial suspicion was that Mercalli, who devised a scale for determining the strength of earthquakes according to the intensity of shaking, had knocked over a paraffin lamp accidentally after falling asleep while working late.

However, an examination of his remains suggested by may have been strangled after disturbing an intruder, who then soaked his clothes in petrol before setting light to them. A sum of money worth the equivalent of $1,400 (€1,250) today was missing, although no one was ever apprehended for the crime.

Born in Milan, Mercalli was ordained a Roman Catholic priest and became a professor of Natural Sciences at the seminary of Milan, although he left under something of a cloud because of his support for Antonio Rosmini, a controversial priest and philosopher who campaigned for social justice and was fiercely critical of various aspects of how the Roman Catholic church operated.

After he had left, the Italian government appointed him a professor at Domodossola in Piedmont, followed by a post at Reggio di Calabria. He was professor of geology at the University of Catania in the late 1880s and was given a post at the Naples University in 1892. He became director of the Vesuvius Observatory in 1911.

He is best remembered for the Mercalli intensity scale for measuring earthquakes which, in modified form, is still used today.

While studying seismic activity in Italy in the late 19th century, Mercalli’s access to seismic instrumentation was limited. Most of Mercalli's information came from personal accounts and observations of damage. To provide consistency in his analyses, he decided he needed a way to measure the relative effects of each event.

He first developed a scale with six degrees, with the most disastrous earthquakes given an intensity of six, but felt that this did not provide enough precision.  Another intensity scale called the deRossi-Forel scale that was gaining in prominence at the same time had the advantage of 10 degrees of intensity, although Mercalli felt it lacked meaningful description.

Mercalli was ordained as a priest before beginning his scientific career

In 1902, Mercalli modified this 10-degree scale to include the detail he desired, and his new scale quickly caught on among European scientists

Mercalli also observed eruptions of the volcanoes Stromboli and Vulcano in the Aeolian Islands and his descriptions of these eruptions became the basis for two indices in the Volcanic Explosivity Index: 1 - Strombolian eruption, and 2 - Vulcanian eruption.

The scale has been tweaked by various other seismologists but remains the basis for determining an earthquake’s intensity. It is now known as the Modified Mercalli Intensity Scale.

Mercalli also engaged in detailed cataloguing of Italian earthquakes, which enabled him to produce a book - I vulcani e fénomeni vulcanici in Italia - which he used to assemble a clear picture of where most of the events happened.

Mercalli's work built his reputation across southern Europe, and he was often called upon to study events throughout the continent.  He travelled to Spain in 1884 to examine the aftermath of the Andalusian earthquake, and in 1887 Mercalli was the lead investigator of the deadly event in Imperia along the French and Italian Riviera.

He became famous even beyond scientific circles, to the extent that his death and the speculation over the circumstances was reported in the New York Times.

Travel tip:

The name Domodossola is familiar to many Italian children as a line - ‘D’ is for Domodossola - recited in learning the alphabet at school. It is, in fact, a very pleasant town in northern Piedmont, close to the border with Switzerland and the last town at the Italian end of the Simplon Pass and the Simplon railway tunnel. Domodossola has a charming medieval centre around the Piazza Mercato, which has a number of interesting buildings. The Collegiale Church of Santi Gervasio and Protasio is the town’s most important church, while just outside the town is the Sacro Monte Calvario, a Roman Catholic sanctuary that is a UNESCO World Heritage site. The Palazzo Silva in Piazza Chiossi houses a civic museum. The area is surrounded by outstanding Alpine countryside, which can be admired from a light railway linking Domodossola and Locarno in Switzerland.

Travel tip:

The Vesuvius Observatory today is part of the Mount Vesuvius National Park, which was created in 1955. The crater of the volcano itself is accessible to visitors, albeit by guided tour only, and there is a road to within 200 metres of it, but after that the ascent is on foot only.  The crater is about 200 metres deep and has a maximum diameter of about 600 metres. The climb is said to be well worth it because the view takes in the entire coastline from the Gulf of Gaeta, some 84km (52 miles) to the north, to the Sorrento peninsula. Visitors can take the Naples-Sorrento line of the Circumvesuviana railway and get off at Ercolano station, from where a shuttle bus runs to the park. As well as the observatory, there is a museum, a visitor centre, a restaurant and a shop where you can buy Lacrima Christi del Vesuvio, the wine made from the grapes grown on the sloped of the volcano.

A huge earthquake destroyed or severely damaged scores of towns and cities in Sicily on this day in 1693, killing more than 60,000 people.

Records say the tremor struck at around 9pm local time and lasted about four minutes.  It was mainly confined to the southeast corner of the island, with damage also reported in Calabria on the Italian mainland and even on Malta, 190km (118 miles) away.

Although it is an estimate rather than a verifiable figure, the earthquake has been given a recorded magnitude of 7.4, which makes it the most powerful in Italian history, although in terms of casualties it was eclipsed by the earthquake that destroyed much of Messina and Reggio Calabria in 1908, with perhaps up to 200,000 killed.

By another measure, the Mercalli intensity scale, it was awarded a score of XI, the maximum.  The Mercalli scale, devised in 1902, judges a quake’s severity by the intensity of shaking. The XI rating given to the 1693 event may well reflect accounts such as that offered by Vincentius Bonajutus, published in the Philosophical Transactions of the Royal Society, who wrote that "It was in this country impossible to keep upon our legs, or in one place on the dancing Earth; nay, those that lay along on the ground, were tossed from side to side, as if on a rolling billow."

At least 70 towns and cities - including Catania, Syracuse (Siracusa), Noto and Acireale - were either very badly damaged or destroyed, with an area of 5,600 sq km (2,200 sq mi) affected.

Locally recorded counts of the dead indicate that there were probably more than 60,000 people killed. Around 12,000 of those - two thirds of the city’s population - were in Catania alone.

More damage and deaths occurred before the main earthquake in a powerful foreshock on January 9, itself with an estimated magnitude of 6.2, and as a result of tsunamis that devastated the coastal villages on the Ionian Sea and in the Straits of Messina.

The exact position of the epicentre remains unknown, although it was probably close to the coast, or slightly offshore, between Catania and Syracuse.  The tsunamis that followed affected some but not all coastal settlements. One place that did suffer was the port of Augusta, north of Syracuse, where the harbour was left drained when the sea receded, only to be swamped by waves of up to eight metres (26ft) high as the waters surged back.

It may seem perverse to talk of good coming from such a catastrophic natural disaster that claimed so many lives, but it is an inescapable fact that had it not been for the 1693 earthquake, much of the wonderful architecture that makes the cities of southeast Sicily so attractive today might not exist.

That it does is thanks to the extravagantly wealthy aristocracy that controlled the purse strings on the island, which was then part of the Spanish empire.

After concentrating initially on restoring military defences around the strategically important Syracuse, Augusta, Catania and Acireale, the island’s government began drawing up of plans for the reconstruction of towns and cities.

Some, such as Catania, would be rebuilt to new plans on their existing sites, others such as Syracuse and Ragusa rebuilt following existing layouts, and others moved to new sites and built from scratch, as was the case with Noto and Avola.

In all cases, dozens of local architects were given palaces and churches to build.  Many had trained under the great Baroque architects in Rome and this was their opportunity, with money apparently no object, to recreate the sophisticated Baroque architecture that had become popular in mainland Italy, but had not really reached Sicily.

On such architect was Vincenzo Sinatra, a pupil of Rosario Gagliardi, who had been influenced by Gian Lorenzo Bernini’s work in Rome.  Sinatra was responsible for many of the new buildings in the new city of Noto, including the churches of Monte Vergine and San Giovanni Battista, the Basilica di Santa Maria Maggiore and its Loggiato, and the splendid Palazzo Ducezio (now the town hall).

Their work inspired more local architects to follow suit and between 1730 and 1780 the style that became known as Sicilian Baroque, characterised by typically Baroque curves and flourishes, but often with the addition of grinning masks or chubby cherubs, was at its peak, reflecting the flamboyance of the era.

Although the fashion for neoclassicism changed the thinking of architects on the island towards the end of the 18th century, it is Sicilian Baroque that gives Sicily much of its architectural character even today.

Other notable Sicilian Baroque architects include Andrea Giganti, Guarino Guarini, Stefano Ittar, Andrea Palma and Giovanni Battista Vaccarini.

As well as its Sicilian Baroque buildings, concentrated on the island of Ortygia, the historic centre linked to the modern city of Syracuse by the Ponte Umbertino, Syracuse is known for its ancient ruins. The Parco Archeologico Neapolis, situated within the city, comprises the Roman Amphitheater, the Teatro Greco and the Orecchio di Dionisio, a limestone cave shaped like a human ear. The Museo Archeologico Regionale Paolo Orsi, meanwhile, exhibits terracotta artifacts, Roman portraits and Old Testament scenes carved into white marble.  Syracuse as a city is listed by UNESCO as a World Heritage Site.

Travel tip:

Ragusa, the principal city of the province of the same name, which also suffered much damage in the earthquake, is one of Sicily’s most picturesque cities. Set in same rugged landscape with a mix of medieval and Baroque architecture. The older part of the city, the spectacular Ragusa Ibla, is the town that was built on the site of the settlement destroyed in the quake, and is home to the grand Duomo di San Giorgio and the Giardino Ibleo, a public park with churches and fountains that offers stunning views.  Ragusa Ibla may seem familiar to viewers of the TV detective series Inspector Montalbano as the dramatic hillside city in the title sequence. The city streets also feature regular in location filming for the series, based on the books of Andrea Camilleri.

Gaetano Russo - sculptor

Creator of New York’s Christopher Columbus Monument



Gaetano Russo's monument to Christopher Columbus has been in place since 1892

The sculptor Gaetano Russo, famous for having created the monument dedicated to Christopher Columbus at Columbus Circle in New York, was born on this day in 1847 in the Sicilian city of Messina.

Russo’s 13ft (3.96m) statue of the 15th century Genoese explorer, carved from a block of Carrara marble, stands on top of a 70ft (21.3m) granite column, decorated with bronze reliefs depicting the Niña, the Pinta and the Santa Maria, Columbus’s three caravel sailing ships.  At the foot of the column there is an angel holding the globe.

Unveiled on October 12, 1892 on the 400th anniversary of Columbus’s voyage to the Americas, the statue was a gift to the city from New York’s Italian-American community, funded by a campaign by an Italian-language newspaper, Il Progresso.

For the laying of the statue’s cornerstone, a procession took place from Little Italy to what is now called Columbus Circle, at the southern end of Central Park, a distance of 6.5km (4.2 miles). Close to 10,000 people are said to have attended the dedication ceremony.

Additional ornamentation around the base of the column depicts Columbus’s journey, American patriotic symbols, and allegorical figures. The monument was restored in 1992 on the occasion of the 500th anniversary of his transatlantic crossing.

Columbus Circle, at the intersection of Broadway, Central Park West, Central Park South (West 59th Street) and Eighth Avenue, has a symbolic importance to New Yorkers, as the traditional geographic centre of the city.

For decades, the Hagstrom Map Company sold maps that showed the areas within 25 miles (40km) or 75 miles (121km) of Columbus Circle. Even today, the New York City government employee handbook defines 'long-distance travel' as a trip beyond a 75-mile (121km) radius of Columbus Circle.

The monument came under threat in 2018 as part of a nationwide review of whether figures regarded traditionally as American heroes, and who were celebrated in statues and other monuments, deserved their status. Columbus was controversial for having taken back indigenous people from the Caribbean to sell in Spain as slaves and there were calls for the statue to be taken down.

However, after Governor of New York Andrew Cuomo, who is descended from Campanian immigrants, had spoken out on behalf of his fellow Italian-Americans in upholding the importance of Columbus in the links between the two countries, it was announced that the statue would stay in place but that there would be notices placed in or around Columbus Circle explaining the history of Columbus and of the monument.

Gaetano Russo was born in Via dell’Oliveto in Messina and baptised in the nearby church of San Leonardo.

Little is known about his early life until 1870, when he received a grant to go to Rome where he studied with Girolamo Masini and Giulio Monteverde.

He worked in both Rome and his native Sicily. In the capital he was commissioned to sculpt bas-reliefs for the facade of the building that now houses the Academy of Dramatic Art, the pediments of the Policlinico Umberto I and the cenotaph dedicated to Felice Bisazza.

In Messina he was commissioned to make funerary sculptures for the monumental cemetery and the monument to Marco Miceli Puglisi, dated 1877, on which stands an imposing winged figure.

No record of Russo exists after 1908 and it is assumed that he died in the devastating earthquake of the same year that destroyed much of Messina and may have killed up to 200,000 people. It is known that his brothers, Letterio and Stellario, both perished and that all the buildings in and around Via dell'Oliveto, a heavily populated area of ​​the city, disappeared.

Travel tip:

Messina is a city in the northeast of Sicily, separated from mainland Italy by the Strait of Messina. It is the third largest city on the island and is home to a large Greek-speaking community. The 12th century cathedral in Messina has a bell tower which houses one of the largest astronomical clocks in the world, built in 1933. Originally built by the Normans, the cathedral, which still contains the remains of King Conrad, ruler of Germany and Sicily in the 13th century, had to be almost entirely rebuilt following the earthquake in 1908, and again in 1943, after a fire triggered by Allied bombings.

Travel tip:

Located in the San Lorenzo quarter, the Policlinico Umberto I of Rome, where Russo sculpted the bas relief figures decorating the pediment over the main entrance, is the polyclinic of the faculty of medicine and surgery of the Sapienza Università di Roma. The city’s main hospital, it is the second largest public hospital in Italy. Its construction was promoted by Italian physicians and politicians Guido Baccelli and Francesco Durante and began in 1883 to plans by Giulio Podesti and Filippo Laccetti. The opening was presided over by the then university rector Luigi Galassi and by King Umberto I, after whom it is named.

Amalfi destroyed by tsunami

Quake beneath Tyrrhenian Sea sparked killer wave


Today Amalfi is a tranquil town with a peaceful harbour - a  far cry from the devastation of 1343
Today Amalfi is a tranquil town with a peaceful harbour - a
far cry from the devastation of 1343
The former maritime republic of Amalfi, which once had a population of 70,000 people, was effectively wiped out when a massive earthquake that occurred under the Tyrrhenian Sea on this day in 1343 sparked a devastating tsunami along the coast of southern Italy.

The tremor itself caused deaths but not on the scale of the tsunami that followed, as a stretch of coastline from north of Naples to south of the Cilento National Park bore the brunt of a huge killer wave.

The towns of Bussanto and Blanda, near the present-day resorts of Sapri and Maratea, were among communities that disappeared completely, while Amalfi and Minori on what we know now as the Amalfi Coast were decimated.

Amalfi’s harbour and all the boats in it were destroyed, while the lower town fell into the sea. Where there had once been a thriving city, only a village remained, the population of which has never grown much beyond about 6,000 people. Its days as a significant maritime power were over.

The poet Petrarch was staying in
Naples at the time of the deadly quake
Salerno and Naples suffered considerable damage, although the death toll was never recorded, it can be assumed it ran into tens of thousands.

What is known today is in part down to the poet Francesco Petrarca - Petrarch - who was staying in Naples at the time of the catastrophe, at the convent of San Lorenzo, and recorded what he had witnessed.

His account, which was contained in a volume of letters entitled Epistolae familiares, described how Naples was in a state of fear on the day of the earthquake, having been warned by Bishop Guglielmo of Ischia that the city would be destroyed. It is thought likely that there had been a series of smaller tremors in the days leading up to the major quake.

Petrarch spoke of a “furious storm” with the only illumination provided by the frequent flashes of lightning, and recorded that “everything began to tremble” soon after he went to bed. He said that people “ran outdoors and tried to avoid things that fell to the ground.”

At first light, when Queen Giovanna was among those surveying the considerable damage to the port, the waters of the bay were seen to recede. Petrarch described the “hideous whiteness of the foam” as the sea suddenly started to retreat.

This was followed, in Petrarch’s words, by "a thousand mountains of waves not black nor blue, as they are usual to be in other storms but very white, they were seen coming from the island of Capri to Naples”.

Among the first victims when the waves hit the Naples shoreline were a thousand soldiers deployed to help survivors of the original quake.  Only one ship in the harbour was not destroyed, Petrarch noting that it had on board 400 convicts

The 1343 tsunami was not the first to be recorded on the Italian coast. After the eruption of Vesuvius in 79AD, Pliny the Younger described what experts have interpreted as a small tsunami.

Present day seismologists warn that the submerged volcano Marsili beneath the Tyrrhenian Sea about 175m (109 miles) south of Naples could pose a threat to millions of people living on the coast. Although it has not erupted in recorded history, volcanologists believe that Marsili is a relatively fragile-walled structure, made of low-density and unstable rocks, fed by an underlying shallow magma chamber.

Marsili belongs to the Aeolian Islands volcanic arc and is the largest active volcano of the chain, larger than Mount Etna. It was discovered during the 1920s and named after Italian geologist Luigi Ferdinando Marsili.

Travel tip:

Although Amalfi is much smaller than it once was, it is still a significant town on the Campania coastline between Sorrento and Salerno, attracting huge numbers of tourists each year.  Its ninth-century Duomo dominates the town's central piazza, sitting at the top of a wide flight of steps. The cloister (Chiostro del Paradiso) and museum close by house sculptures, mosaics and other relics.  Radiating away from the cathedral, narrow streets offer many souvenir shops and cafes for visitors.  Amalfi is accessible by bus from Sorrento and Salerno and there are boat services that run along the coast.

Travel tip:

Salerno, which has a population of about 133,000, is a city often overlooked by visitors to Campania, who tend to flock to Naples, Sorrento, the Amalfi coast and the Cilento, but it has its own attractions and is a good base for excursions both to the Amalfi coast and the Cilento, which can be found at the southern end of the Gulf of Salerno. Hotels are cheaper than at the more fashionable resorts, yet Salerno itself has an attractive waterfront and a quaint old town, at the heart of which is the Duomo, originally built in the 11th century, which houses in its crypt the tomb of one of the twelve apostles of Christ, Saint Matthew the Evangelist.  The city can be reached directly by train from Naples, which is about 55km (34 miles) north.
