Mantle seismic structure beneath the United States spanning from the active western plate
margin to the passive eastern margin was imaged with teleseismic P and S wave traveltime …

We present a new, 3D description of crust and upper mantle velocity structure in southern
California implemented as a Unified Structural Representation (USR). The USR is …

The deep extension of the San Andreas Fault is believed to be creeping, but the recent
observations of tectonic tremors from these depths indicate a complex deformation style. In …

Seismicity along continental transform faults is usually confined to the upper half of the crust,
but the Newport-Inglewood fault (NIF), a major fault traversing the Los Angeles basin, is …

We analyze teleseismic P waves from four Mw≥ 6.5 earthquakes recorded by a petroleum
industry survey in Long Beach, California. The survey used a 2‐D array with up to 5200 …

Southcentral Alaska is a complex tectonic region that transitions from subduction of Pacific
crust to flat slab subduction—and collision—of overthickened Yakutat crust. Because much …

Abstract The 4 April 2010 Mw 7.2 El Mayor‐Cucapah (EMC) earthquake in Baja, California,
and Sonora, Mexico, had primarily right‐lateral strike‐slip motion and a minor normal‐slip …

Due to its location on a transtensional section of the Pacific-North American plate boundary,
the Salton Trough is a region featuring large strike-slip earthquakes within a regime of …

We present a series of Moho depth maps for the Alaskan region based on P receiver
function estimates using data from all available broadband instrumentation from 1999 to …

Abstract The western North American lithosphere experienced extensive magmatism and
large-scale crustal deformation due to the interactions between the Farallon and North …
