The Current Stress State and Seismic Hazard in the Kunlun Pass Region Following the Ms 8.1 Earthquake in 2001
Source abstract
Abstract
The Kusaihu and Xidatan faults in the western part of the East Kunlun active fault present a miter compound relationship. The Quaternary activity of these two faults is vigorous and closely associated with potent and large earthquakes. The Ms 8.1 earthquake occurred on the Kusai Lake fault on 14 November 2001. To understand the current stress state and seismic hazard in the Kunlun pass region following the Ms 8.1 Earthquake in 2001, the in situ stress measurement work of four boreholes at two measuring points in this area is conducted through the hydraulic fracturing method, and the in situ stress accumulation level in this area is analyzed using the Coulomb fracture criterion, Byerlee’s law, and the fault friction parameter μm. It is found that the in situ stress accumulation level in the study area is not high, and the possibility of fault slip is low.
