Gesualdo is an Italian town in the province of Avellino, itself in the region of Campania. It is called "The city of the Prince of Musicians" in honour of Carlo Gesualdo. It has many palaces, fountains, belvederes, and a historical center, which was partially restored after the Irpinia earthquake in 1980.
The Assam earthquake of 1897 occurred on 12 June, in Assam, British India at 11:06 UTC, and had an estimated moment magnitude of 8.2–8.3. It resulted in approximately 1,542 human casualties and caused catastrophic damage to infrastructures. Damage from the earthquake extended into Calcutta, where dozens of buildings were severely damaged, with some buildings partially collapsing. Trembles were felt across India, reaching as far as Ahmedabad and Peshawar. Seiches were also observed in Burma.
Calabritto is an Italian town and a commune in the province of Avellino, Campania, Italy. It occupies a hilly-mountainous area at the eastern tip of the Monti Picentini range, in the upper Sele valley.
Guardia Lombardi, known as La Uàrdia in the Irpinian dialect, is a small town and comune in the Province of Avellino in Campania, Italy. At an elevation of 998 metres (3,274 ft), it is located in Irpinia in the Apennine Mountains of Southern Italy. It has experienced a number of major earthquakes throughout its history that have devastated the town, and is considered within zone 1 of the Protezione Civile's seismic classification index, indicating very high seismicity.
Irpinia is a geographical and cultural region of Southern Italy. It was the inland territory of the ancient Hirpini tribe, and its extent matches approximately today's province of Avellino.
The 1980 Irpinia earthquake took place in Italy on 23 November 1980, with a moment magnitude of 6.9 and a maximum Mercalli intensity of X (Extreme). It left at least 2,483 people dead, at least 7,700 injured, and 250,000 homeless.
The 1703 Genroku earthquake occurred at 02:00 local time on December 31. The epicenter was near Edo, the forerunner of present-day Tokyo, in the southern part of the Kantō region, Japan. An estimated 2,300 people were killed by the destruction and subsequent fires. The earthquake triggered a major tsunami which caused many additional casualties, giving a total death toll of at least 5,233, possibly up to 200,000. Genroku is a Japanese era spanning from 1688 through 1704.
The following is a summary of significant earthquakes during the 21st century. In terms of fatalities, the 2004 Indian Ocean earthquake was the most destructive event with 227,898 confirmed fatalities, followed by the 2010 Haiti earthquake with about 160,000 fatalities, the 2008 Sichuan earthquake with 87,587 fatalities, the 2005 Kashmir earthquake suffered by Pakistan with 87,351 fatalities, and the 2023 Turkey–Syria earthquakes with at least 59,488 fatalities.
This list of 20th-century earthquakes is a list of earthquakes of magnitude 6 and above that occurred in the 20th century. Sone smaller events which nevertheless had a significant impact are also included. After 1900 most earthquakes have some degree of instrumental records and this means that the locations and magnitudes are more reliable than for earlier events.
The 1930 Irpinia earthquake occurred at 00:08 UTC on 23 July, chiefly in an area known as Irpinia. It had a surface-wave magnitude of 6.6 and a maximum intensity of X . The event caused 1,404 deaths and 4,624–7,000 injuries. The epicenter was near the boundaries between the regions of Basilicata, Apulia, and Campania.
On 5 February AD 62, an earthquake of an estimated magnitude of between 5 and 6 and a maximum intensity of IX or X on the Mercalli scale struck the towns of Pompeii and Herculaneum, severely damaging them. The earthquake may have been a precursor to the eruption of Mount Vesuvius in AD 79, which destroyed the same two towns. The contemporary philosopher and dramatist Seneca the Younger wrote an account of the earthquake in the sixth book of his Naturales quaestiones, entitled De Terrae Motu.
The 1935 Helena earthquake occurred at in Montana, with an epicenter near Helena. It had a magnitude of 6.2 on the surface-wave magnitude scale and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale. The temblor on that date was the largest of a series of earthquakes that also included a large aftershock on October 31 of magnitude 6.0 and a maximum intensity of VIII. Two people died in the mainshock and two others died as a result of the October 31 aftershock. Property damage was over $4 million.
The area around Constantinople was affected by a major earthquake in AD 447. It caused serious damage to the recently completed Theodosian Walls in Constantinople, destroying 57 towers and large stretches of the walls. The historical records contain no mention of casualties directly associated with this earthquake, although many thousands of people were reported to have died in the aftermath due to starvation and a "noxious smell".
On December 5, 1456, the largest earthquake to occur on the Italian Peninsula in historical times struck the Kingdom of Naples. The earthquake had an estimated moment magnitude of Mw 7.19–7.4, and was centred near the town of Pontelandolfo in the present-day Province of Benevento, southern Italy. Earning a level of XI (Extreme) on the Modified Mercalli intensity scale, the earthquake caused widespread destruction in central and southern Italy. Estimates of the death toll range greatly with up to 70,000 deaths reported. It was followed by two strong Mw 7.0 and 6.0 earthquakes to the north on December 30. The earthquake sequence is considered the largest in Italian history, and one of the most studied.
The second shock in the 1962 Irpinia earthquake sequence was the largest and most destructive in a series of earthquakes in the southern Apennines. It occurred on 21 August at 18:19 CET, measuring 6.15 and assigned a maximum intensity of IX (Violent). It was preceded by an Mw 5.68 foreshock, and followed by a 5.34 aftershock. The earthquakes resulted in nearly 20 fatalities and significant property losses.
The 1941 Hyūga-nada earthquake occurred off the coast of Kyushu, Japan at 19:02 local time on November 19. The earthquake measured 8.0 Mw and had a depth of 35 km (22 mi). A JMA seismic intensity of 5 was observed in Miyazaki City and Nobeoka City in Miyazaki Prefecture, and Hitoyoshi City in Kumamoto Prefecture. Due to the earthquake, a tsunami with a maximum wave height of 1.2 m was observed in Kyushu and Shikoku. The tsunami washed away many ships. Twenty-seven homes were destroyed and two people were killed. In Miyazaki, Ōita and Kagoshima prefectures, telephone services were disrupted. Subsidence by 8 cm (3.1 in) was recorded at Hyūga, Miyazaki. At Nobeoka, stone walls and embankments were damaged while roads cracked. It was felt as far as central Honshu.
