An earthquake measuring 5.8 Mw struck the province of Sichuan in China at 22:55 local time (14:55 UTC), 17 June 2019.[1] Changning and Gong counties in Yibin were particularly affected. 13 people died and more than 200 others were injured.[2]
Tectonic setting
Sichuan lies within the zone of complex tectonics caused by the continuing convergence of the Indian Plate with the Eurasian Plate. The active faulting in this area relates to the eastward movement of material away from the Tibetan Plateau, which has been uplifted by this collision. The largest structure in the area is the Longmenshan Fault, movement on which was responsible for the M7.9 2008 Sichuan earthquake.[1]
