The 2020 Kashgar earthquake, also known as the Jiashi earthquake occurred on 19 January 2020 at 21:27:56
Tectonic setting
Northern Xinjiang lies at the northernmost extreme zone of
The fold and thrust belt is seismically active and is the source of many moderately large to major events with
The slip rate along the shallow frontal part of the Kalping fold and thrust belt has been measured at 1 to 2 mm/yr or just one-fourth the rate of subduction of the Tarim basin. This differs from most zones of convergence where the outermost thrust results in the greatest deformation and accommodates the most slip. Because much of the geological deformation and activity is not at the outer thrusts, the faults are moving at much slower rates. While the faults of the Kalping fold and thrust belt are active and seismogenic, much of the décollement is not due to the lack of friction. It instead displays aseismic creep at depth.[12]
Earthquake
According to the United States Geological Survey, the earthquake ruptured with a shallow focal depth of 5.6 km at the foothills of the Tien Shan mountains. The epicenter of the earthquake is located in close proximity to the G3012 Turpan–Hotan Expressway, or 104 km east northeast of the city of Kashgar.[1]

Characteristics
A more recent analysis of the event reveals that this occurred beneath the shallow décollement, consistent with earlier earthquakes in 1997, 1998, and 2003.[16] By relocating the hypocenter, a different focal depth was found, 15–18 km beneath the fold and thrust belt. It is thought to involve a rupture on a much deeper and older fault structure.[16]
Impact
The earthquake had a maximum intensity of VIII on the
According to a local villager in Guleruk Township, Jiashi County who survived the earthquake, it was described as violent and "like thunder", adding that the shaking lasted for 20 to 30 seconds.One person was seriously injured and was reported deceased later.[17] Local media then reported that "many" people also sustained light injuries due to the earthquake. This claim was later specified to just two individuals suffering minor injuries and one person dying.[18] The Xinjiang Railway Department immediately suspended 9 passenger trains from operating in the affected area.[19]
Local emergency workers inspected some 206 homes and found eight total collapses, 122 with collapsed walls and 68 with partially cracked or fallen walls.[20] Four self-constructed shops totally collapsed in the earthquake and 52 other homes had moderate damage. Another 955 homes sustained light damage. A 1.1 km and 5.6 km-long wall also collapsed due to the quake. Roads including a major highway and transmission lines were severely compromised by the temblor as well.
