Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.
The 2008 Yingjiang earthquakes were a series of major earthquakes ranging from surface wave magnitude (Ms) 4.1 to 5.9 that struck Yingjiang County, Yunnan province, China between August 19 and September 3. It caused 5 deaths, 130 injuries, and RMB 2.7 billion in direct economic damage. USGS put the magnitude of the strongest one to Mw 6.0.
The 1998 Ninglang earthquake (1998年宁蒗地震) occurred on November 19 at 19:38 local time. The epicenter was near the border between the provinces of Sichuan and Yunnan, China. The United States Geological Survey stated that the epicenter was located in the Sichuan Province, while the China Earthquake Data Center provided a different location in Lanniqing Township (烂泥箐乡), Ninglang, Yunnan Province. The magnitude of the earthquake was put at Ms 6.2 and it caused five deaths, with 208 seriously injured in Yunnan and 20 people seriously injured in Sichuan. Building damage was reported in Ninglang, Yunnan and Yanyuan, Sichuan. A dammed lake was formed by a landslide in the Lanniqing Township.
The 2014 Ludian earthquake struck Ludian County, Yunnan, China, with a moment magnitude of 6.1 on 3 August. The earthquake killed at least 617 people, injuring at least 2,400 others. As of 5 August 2014, 112 people remain missing. Over 12,000 houses collapsed and 30,000 were damaged. According to the United States Geological Survey, the earthquake occurred 29 km (18 mi) WSW of Zhaotong city at 16:30 local time (08:30 UTC).
The 2014 Jinggu earthquake occurred on October 7, 2014 at 21:49 (UTC+8).
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 killed; more than 7,700 were injured. Both earthquakes resulted in US$270 million in damage and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.
On May 21, 2021, a 6.1 magnitude earthquake struck the Dali City, Yunnan, China, at a depth of 10.0 km. Three people died during the quake, while another 32 were injured. The earthquake was referred by the Chinese media as the 5.21 earthquake or 2021 Yangbi earthquake.
The 2021 Maduo earthquake, also known as the 5.22 earthquake struck Madoi County in Qinghai Province, China on 22 May at 02:04 local time. The earthquake had a moment magnitude and surface-wave magnitude of 7.4. Highway bridges, roads and walls collapsed as a result of the earthquake. According to an anonymous source, at least 20 people were killed, 300 were injured, and 13 were missing. Officials stated that there were no deaths but 19 people sustained minor injuries. It was the strongest in China since 2008. It was assigned a maximum intensity of X in Machali, Maduo County on the China seismic intensity scale and Modified Mercalli intensity scale. This earthquake was preceded by another unrelated earthquake that occurred 5 hours earlier in Yunnan.
The 2021 Luxian earthquake was a damaging seismic event occurring in the early hours of September 16 at 04:33 China Standard Time. The surface wave magnitude (Ms ) 6.0 or moment magnitude (Mw ) 5.4 earthquake struck at a shallow depth of 7.5 km and severe shaking in an area of 4,000 square kilometers was assigned a maximum intensity of VIII on the China seismic intensity scale. Three people were killed and 146 injured when the earthquake struck Lu County, Luzhou, Sichuan Province. At least 36,800 buildings were affected, 7,800 of them seriously damaged or completely destroyed, causing about a quarter of a billion dollars worth of damage.
On June 1, 2022, a moment magnitude (Mw ) 5.8 or surface-wave magnitude (Ms ) 6.1 earthquake struck Lushan County in Ya'an, Sichuan Province, China. At least four people were killed and 42 were injured. The earthquake had a maximum intensity of VIII on the China seismic intensity scale, causing damage to many homes and triggering rockslides.
A Mw 6.7 earthquake struck Luding County in Sichuan province, China on 5 September 2022 at 12:52:19 local time. The epicenter was located 226 km (140 mi) from Chengdu, or 43 km (27 mi) southeast of Kangding. Ninety-three people died, 424 were injured and 24 remained missing. More than 13,000 homes and other infrastructure were damaged or destroyed. It was the largest earthquake to strike the province since 2017.
Two earthquakes affected Taitung and Hualien Counties, Taiwan within hours of each other. The first earthquake struck Taitung on September 17, 2022, occurring with a magnitude of 6.5 Mw , causing minor damage and some injuries. The second earthquake occurred roughly a day after the first tremor struck the same area, with a stronger magnitude of 6.9 Mw . Both earthquakes had maximum Modified Mercalli intensities of VII and IX (Violent), respectively.
