Compilation of almost 200 new maximum horizontal stress (SHmax) orientations in Texas reveals a complex intraplate stress field. A large extensional stress province is associated with extensive growth faulting from northeastern Mexico to Louisiana. SHmax is subparallel to the coastline, following the strikes of the growth faults. In contrast, we observe a strike-slip/normal faulting regime with...

[1] We argue that key features of thrust earthquake triggering, inhibition, and clustering can be explained by Coulomb stress changes, which we illustrate by a suite of representative models and by detailed examples. Whereas slip on surface-cutting thrust faults drops the stress in most of the adjacent crust, slip on blind thrust faults increases the stress on some nearby zones, particularly ab...

Abstract The Eastern California shear zone is a complex set of dextral faults that accommodates significant plate motion and has produced large earthquakes. evolution this system why it consists closely spaced, irregular fail in multi‐fault ruptures are not well understood. Here we analyze the geometry, spatial distribution, Quaternary slip activity right‐lateral southern Mojave block. We find ...

On 24 August 2014, the M 6.0 South Napa earthquake shook much of the San Francisco Bay area, leading to significant damage in the NapaValley. The earthquake occurred in the vicinity of the West Napa fault (122.313° W, 38.22° N, 11.3 km), a mapped structure located between the Rodger’s Creek and Green Valley faults, with nearly pure right-lateral strike-slip motion (strike 157°, dip 77°, rake –1...

S U M M A R Y The Mw 7.6 1997 Manyi earthquake occurred in an area of central northern Tibet where sparse vegetation coverage and a lack of human habitation provide excellent conditions for Interferometric Synthetic Aperture Radar (InSAR) studies. We use coseismic pairs of radar images acquired by the ESA ERS-2 satellite to construct interferograms of the surface displacement field due to the e...

By applying conventional cross-track InSAR and multiple-aperture InSAR (MAI) techniques with ALOS-2 SAR data to foreshocks of the 2016 Kumamoto earthquake, ground displacement fields in range (line-of-sight) and azimuth components have been successfully mapped. The most concentrated crustal deformation with ground displacement exceeding 15 cm is located on the western side of the Hinagu fault z...

[1] Analysis and modeling of InSAR data covering the 2008 Reno-Mogul M 4.7 earthquake swarm indicate that the main event was produced by slip on a previously unrecognized strike-slip fault in the Reno basin. Deformation of 0.5– 2.5 cm in radar line-of-sight was produced by the main event and post-seismic slip over an area of more than 150 km. This earthquake is one of the smallest magnitude eve...

Fling-step and forward directivity are two important characteristics of near-field earthquakes. Forward directivity occurs when the rupture propagates toward the site and arises in fault‐normal direction for strike‐slip faults. Fling-step is the consequence of permanent ground displacement imposed by near-field earthquakes and arises in strike-slip faults in the strike parallel direction. Fling...

We extend a technique previously used to model surface displacements resulting from thrust faulting in an elastic-gravitational l yer over a viscoelastic-gravitational h f-space to the case of strike-slip faulting. The method involves the calculation of the Green's functions for a strike-slip point source contained in an elastic-gravitational layer over a viscoelastic-gravitational half-space. ...
