It had an estimated magnitude of as high as 8.8 on the moment magnitude scale and a maximum estimated intensity of XI (Extreme) on the Mercalli intensity scale. It triggered a local tsunami in the Bay of Bengal and caused at least 200 deaths. The earthquake was associated with major areas of both uplift and subsidence. It is also associated with a change in course of the Brahmaputra River to from east of Dhaka to 150 kilometres (93 mi) to the west via the Jamuna River.
The 1941 Andaman Islands earthquake struck the Andaman Islands on June 26 with a magnitude of 7.7 to 8.1. Details of this event are poorly known as much of Southeast Asia was in the turmoil of World War II. The quake caused severe damage in the Andaman Islands. The tsunami it triggered was reported along the Andaman and Nicobar Islands, India, and Sri Lanka. There may have been damage and deaths in Bangladesh, Myanmar, and Thailand due to the tsunami.
An earthquake occurred on 1 June 1786 in and around Kangding, in what is now China's Sichuan province. It had an estimated magnitude of about 7.75 and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. The initial quake killed 435 people. After an aftershock ten days later, a further 100,000 died when a landslide dam collapsed across the Dadu river.
Qiongshan earthquake (Chinese:瓊山地震) was an earthquake in 1605 on the 13th of July that struck Hainan and the adjacent Guangdong province in China with an estimated magnitude of 7.5 with a maximum felt intensity of X (Extreme) on the Modified Mercalli intensity scale. It caused widespread damage, including the subsidence of large areas of farmland, swamping many villages and several thousand people were killed.
The 1988 Lancang–Gengma earthquakes, also known as the 11.6 earthquakes by the Chinese media were a pair of devastating seismic events that struck Lancang and Gengma counties, Yunnan, near the border with Shan State, Burma. The earthquake measured moment magnitude (Mw ) 7.0 and was followed 13 minutes later by a 6.9 Mw shock. These earthquakes were assigned a maximum China seismic intensity of IX and X, respectively. Between 748 and 939 people were kille; more than 7,700 were injured. Both earthquakes resulted in US $270 million in damages and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.
The Great Tancheng earthquake, also known as the Shandong earthquake, was a major seismic event that occurred during the rule of the Qing dynasty. The earthquake occurred in Shandong Province on July 25, 1668. The earthquake had an estimated magnitude of Ms 8.5, making it the largest historical earthquake in East China, and one of the largest to occur on land. The earthquake had cataclysmic implications to the region. An estimated 43,000 to 50,000 lives were lost in the earthquake, and its effects were widely felt. The epicenter may have been located between Ju County and Tancheng counties, northeast of the prefecture-level city of Linyi in southern Shandong.
The 1739 Yinchuan–Pingluo earthquake rocked the northern Ningxia Hui Autonomous Region on January 3 with an epicenter in the prefecture-level city Shizuishan. The estimated magnitude 7.1–7.6 earthquake had a maximum intensity of XI on the Mercalli intensity scale, and killed about 50,000 residents and officials. It was widely felt; perceived in Shanxi, Shaanxi and Hebei provinces. Aftershocks persisted for more than two years with the largest being a 5.5 on February 13 that same year.
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 region of Zhili was struck by a major earthquake with an estimated magnitude of 7.5 or 7.4 on June 12, 1830. The epicentre was close to Cixian, which suffered the most severe damage. A total of 7,477 people died as a result of the earthquake.
Western Henan and southern Shanxi in northern China were struck by an earthquake of estimated magnitude 6.8 on 23 October 1815. The epicentre was in Pinglu County in southernmost Shanxi, which was the worse affected area. It had a maximum felt intensity of IX (violent) on the Modified Mercalli scale. It caused the collapse of many houses and cave dwellings and led to the deaths of at least 13,000 people.
The 1872 Amik (Antioch) earthquake occurred on April 3 with an epicenter the Amik Valley in the Ottoman Empire. Earthquake catalogs place the surface-wave magnitude at Ms 7.2 and MSK 64 rating at XI (Catastrophic). Turkey and Syria were devastated by this earthquake, and the region lost at least 1,800 residents.
The region of Ningxia was struck by a major earthquake on the morning of 14 October 1709. It had an estimated magnitude of 7.5 and a maximum felt intensity of X (extreme) on the Modified Mercalli intensity scale. The city of Zhongwei was badly damaged, including a section of the Great Wall. A total of 2,032 people were killed.
The 1867 Central Java earthquake occurred on June 10 at between 04:20 and 04:30 local time. It struck off the southern coast of the Indonesian island with an estimated moment magnitude of 7.8 (Mw ). Widespread devastation occurred in Central Java, where as many as 700 people were killed. The intermediate-depth intraslab earthquake did not cause a tsunami.
