On March 31, 2020, an Mw 6.5 earthquake struck near Stanley, Idaho. More than 35% nondouble-couple component in long-period point-source solutions indicate a more complex source slip on planar fault. Using integrative analysis of seismological and geodetic data, we find that the Stanley ruptured pair opposing-dip faults offset by 10-km-wide step, including unmapped northern subfault with predom...

Abstract The Jiacha Gorge in southeastern Tibet is the second-largest deeply incised gorge of Yarlung-Tsangpo River, after Tsangpo Gorge. A late Cenozoic N-S–trending normal fault, Woka Rift coincides with western limit gorge. However, relationship between formation gorge, drainage evolution, and rift activity remains unclear. Analysis river long profile suggests that developed as a ~45-km-wide...

Several synthetic models are constructed to fit the first 40 sec of the transversely polarized displacement, as recorded at El Centro, of the April 9, 1968 Borrego Mountain earthquake. The modeling is done in the time domain using the response computed for a distributed set of point shear dislocations embedded in a layered half-space. The beginning 1 0 sec of the observed record is used to mode...
