An earthquake measuring 5.8 Mw struck the province of Sichuan in China at 22:55 local time (14:55 UTC), 17 June 2019.
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 reverse fault movement matches well with the known stress field in the area, but the strike-slip fault is less favourably orientated, suggesting the presence of elevated pore pressures due to water injection associated with solution mining of rock salt.
[4] Results from the analysis of Interferometric synthetic-aperture radar (InSAR) data indicate that the reverse fault was shallow enough to be intersected by the openhole sections of some of the injection wells.
[6] More than 20,000 houses were badly damaged and some roads, communication infrastructure and hydroelectric power plants were also reported to be affected.
