We describe best-fitting angular velocities and MORVEL, a new closure-enforced set of
angular velocities for the geologically current motions of 25 tectonic plates that collectively …

The origin of rupture segmentation along subduction zone megathrusts and linkages to the
structural evolution of the subduction zone are poorly understood. Here, regional-scale …

The variation of elastic-wave velocities as a function of the direction of propagation through
the Earth's interior is a widely documented phenomenon called seismic anisotropy. The …

Abstract Episodic Tremor and Slip, or ETS, is a well‐recognized phenomenon in the
Cascadia subduction zone. Constraining the precise location of geodetically measured slip …

Coastal marshes record a 6500 yr history of coseismic displacements in great earthquakes
at the Cascadia subduction zone. We compiled estimates of coseismic displacement for past …

SUMMARY A new amphibious seismic data set from the Cascadia subduction zone is used
to characterize the lithosphere structure from the Juan de Fuca ridge to the Cascades …

The long‐term average velocity field of the western United States is computed with a
kinematic finite element code. Community data sets include fault traces, geologic offset …

Abstract Great megathrust earthquakes (magnitude 8+) do not typically rupture an entire
convergent margin but rather are limited to one or more along‐strike segments. A …

The dehydration of oceanic slabs during subduction is mainly thermally controlled and is
often expressed as intermediate‐depth seismicity. In warm subduction zones, shallow …

In the central Oregon Cascades, extension of the arc has promoted eruption of primitive
basalts that are of three types, calcalkaline (CAB), low K tholeiitic (LKT) and rare absarokitic …
