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 shaking 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 10,000. Genroku is a Japanese era spanning from 1688 through 1704.
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 1751 Port-au-Prince earthquake occurred at 12:50 UTC on 21 November in French Haiti, followed by a tsunami. Another earthquake was reported at the same location on 15 September of the same year and it is uncertain whether the two reports refer to the same event.
The 1868 Ecuador earthquakes occurred at 19:30 UTC on August 15 and 06:30 UTC on 16 August 1868. They caused severe damage in the northeastern part of Ecuador and in southwestern Colombia. They had an estimated magnitude of 6.3 and 6.7 and together caused up to 70,000 casualties. The earthquake of 15 August occurred near El Ángel, Carchi Province, close to the border with Colombia, while that of August 16 occurred near Ibarra in Imbabura Province. Reports of these earthquakes are often confused with the effects of the earthquake of 13 August at Arica.
The 1290 Zhili earthquake occurred on 27 September with an epicenter near Ningcheng, Zhongshu Sheng (Zhili), Yuan China. This region is today administered as part of Inner Mongolia, China. The earthquake had an estimated surface wave magnitude of 6.8 and a maximum felt intensity of IX (Violent) on the Mercalli intensity scale. One estimate places the death toll at 7,270, while another has it at 100,000.
The 1667 Shamakhi earthquake occurred on 25 November 1667 with an epicenter close to the city of Shamakhi, Azerbaijan. It had an estimated surface wave magnitude of 6.9 and a maximum felt intensity of X (Extreme) on the Mercalli intensity scale. An estimated 80,000 people died.
The 1727 Tabriz earthquake occurred on 18 November with an epicenter near Tabriz in northwest Iran. The maximum felt intensity was VIII (Severe) on the Mercalli intensity scale, and there were an estimated 77,000 deaths. The only record for this earthquake comes from an account written in 1821 and it is very likely that the information for this earthquake refers instead to the 1721 Tabriz earthquake.
The 1293 Kamakura earthquake in Japan occurred at about 06:00 local time on 27 May 1293. It had an estimated magnitude of 7.1–7.5 and triggered a tsunami. The estimated death toll was 23,024. It occurred during the Kamakura period, and the city of Kamakura was seriously damaged.
Events in the year 1841 in Portugal.
The 1615 Arica earthquake was a major earthquake centered near Arica in the Spanish colonial Viceroyalty of Peru, within the present day Arica y Parinacota Region of northwestern Chile.
The 1897 Mindanao earthquakes occurred on September 20, 1897, at 19:06 UTC and September 21, 1897, at 05:12 UTC. The estimated epicentres of the two earthquakes are identical, lying just off the southwestern coast of Mindanao in the Philippines, south of Basilan island. The earthquakes were originally given estimated magnitudes of 8.6 and 8.7 on the surface wave magnitude scale by Charles Richter, but these were revised downwards by Katsuyuki Abe to 7.4 and 7.5 Ms, respectively. Contemporary reports noted that with few exceptions, all the masonry buildings in Zamboanga and Basilan were left in ruins.
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".
The western coast of West Sulawesi was struck by a major earthquake on 23 February 1969 at 00:36 UTC. It had a magnitude of 7.0 Mw and a maximum felt intensity of VIII on the Modified Mercalli intensity scale. It triggered a major tsunami that caused significant damage along the coast of the Makassar Strait. At least 64 people were killed, with possibly a further 600 deaths caused by the tsunami.
During April 1819, the area around Copiapó in northern Chile was struck by a sequence of earthquakes over a period of several days. The largest of these earthquakes occurred on 11 April at about 15:00 local time, with an estimated magnitude of Mw 8.5. The other two events, on 3 April between 08:00 and 09:00 local time and on 4 April at 16:00 local time, are interpreted as foreshocks to the mainshock on 11 April. The mainshock triggered a tsunami that affected 800 km of coastline and was also recorded at Hawaii. The city of Copiapó was devastated.
The 1872 Amik (Antakya) earthquake occurred on April 3 with an epicenter within the Amik Valley in the Ottoman Empire. Earthquake had an estimated magnitude of Mw 7.0–7.2 or Ms 7.2 and maximum MSK 64 rating of XI (Catastrophic). Turkey and Syria were devastated by this earthquake, and the region lost at least 1,800 residents.
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.
