The 1877 Iquique earthquake occurred at 21:16 local time on 9 May. It had a magnitude of 8.5 on the surface wave magnitude scale. Other estimates of its magnitude have been as high as 8.9 and 9.0 . It had a maximum intensity of XI (Extreme) on the Mercalli intensity scale and triggered a devastating tsunami. A total of 2,385 people died, mainly in Fiji.
The 1893 Quchan earthquake occurred at about 19:30 local time on 17 November. It had an estimated magnitude of 6.6 on the surface wave magnitude scale and a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale. It caused severe damage in Quchan County, particularly to the town of Quchan itself and there were an estimated 18,000 casualties.
The 1721 Tabriz earthquake occurred on April 26, with an epicenter near the city of Tabriz, Iran. It leveled some three-quarters of the city, including many prominent mosques and schools in the city, and resulted in the deaths of tens of thousands of people. The total number of casualties caused by the earthquake is between 8,000 and 250,000; it was most likely approximately 80,000. At the time that it occurred, the earthquake was popularly interpreted as an omen of misfortune, or a demonstration of godly wrath. The destruction that the earthquake caused was a significant factor in the successful Ottoman takeover of Tabriz in 1725, as well as contributing to Tabriz's economic difficulties during that period. It also caused the destruction of some of the city's significant historical monuments. Accounts of the earthquake are often confused with descriptions of the 1727 Tabriz earthquake.
The 1981 Golbaf earthquake occurred on June 11 at with a moment magnitude of 6.6 and a maximum Mercalli intensity of VIII+ (Severe). Total damage was considered moderate and amounted to $5 million in financial losses, with many injured, and 1,400–3,000 killed.
The 1869 Cachar earthquake occurred on 10 January with an estimated moment magnitude of 7.4 and a maximum EMS-98 intensity of VII (Damaging). Two people were killed and damage was considered severe. The earthquake was felt in Upper Burma, Bihar, Jharkhand, Bengal and Northeast India.
The 2004 Baladeh earthquake occurred on May 28 in northern Iran. This dip-slip earthquake had a moment magnitude of 6.3 and a maximum Mercalli intensity of VIII (Severe). Total deaths for the event amounted to 35, with 278–400 injured, and $15.4 million in damage.
The 1843 Guadeloupe earthquake occurred at 10:37 local time on 8 February in the island of Guadeloupe in the Lesser Antilles. It had an estimated magnitude of 8.5, making it the strongest recorded earthquake in the Caribbean and a maximum perceived intensity of shaking of IX on the Mercalli intensity scale. The earthquake was felt widely throughout the Caribbean and as far away as New York. Around 1,500 to 5,000 people were killed.
The 1780 Tabriz earthquake occurred at 01:15 local time on 8 January. It had an estimated magnitude of 7.4 and a maximum felt intensity of IX on the Mercalli intensity scale. The city of Tabriz was almost completely destroyed. The number of reported casualties varies from 40,000 to as many as 200,000, with 50,000 being a more likely estimate.
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 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.
The Fars region of Iran was struck by a major earthquake on either 22 April or 5 May 1853. The city of Shiraz and the surrounding area were severely affected, with almost all buildings destroyed. At least 9,000 people were killed, with some estimates reaching 13,000.
