Active megadetachment beneath the western United States [PDF]

open access: yes, 2008
Geodetic data, interpreted in light of seismic imaging, seismicity, xenolith studies, and the late Quaternary geologic history of the northern Great Basin, suggest that a subcontinental-scale extensional detachment is localized near the Moho.

Probing Slow Earthquakes With Deep Learning

open access: yesGeophysical Research Letters, 2020
Slow earthquakes may trigger failure on neighboring locked faults that are stressed sufficiently to break, and slow slip patterns may evolve before a nearby great earthquake.

Juan de Fuca subduction zone from a mixture of tomography and waveform modeling [PDF]

open access: yes, 2012
Seismic tomography images of the upper mantle structures beneath the Pacific Northwestern United States display a maze of high-velocity anomalies, many of which produce distorted waveforms evident in the USArray observations indicative of the Juan de ...

Evidence for late Quaternary surface rupture along the Leech River fault near Victoria, British Columbia [PDF]

open access: yes, 2016
New surficial and bedrock mapping and paleoseismic trenching of the Leech River fault provide the first evidence for Quaternary surface-rupturing earthquakes in southwestern British Columbia, Canada.

Stress buildup in the Himalaya [PDF]

open access: yes, 2004
The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Coseismic slip distributions are generally heterogeneous

Subduction plate age as a control on elastic upper-plate thickness in Cascadia: Insights from interseismic GNSS observations and implications

open access: yesEarth and Planetary Physics
Understanding the viscoelastic structure of subduction zones is essential for assessing seismic hazards and understanding subduction-zone dynamics.

Very Low Frequency Earthquakes in Between the Seismogenic and Tremor Zones in Cascadia?

open access: yesAGU Advances, 2022
Megathrust earthquakes and their associated tsunamis cause some of the worst natural disasters. In addition to earthquakes, a wide range of slip behaviors are present at subduction zones, including slow earthquakes that span multiple orders of spatial ...

In situ benthic fluxes from an intermittently active mud volcano at the Costa Rica convergent margin [PDF]

open access: yes, 2005
Along the erosive convergent margin off Costa Rica a large number of mound-shaped structures exist built by mud diapirism or mud volcanism. One of these, Mound 12, an intermittently active mud volcano, currently emits large amounts of aqueous dissolved ...

Sedimentary record of coseismic subsidence in Hersek coastal lagoon (Izmit Bay, Turkey) and the late Holocene activity of the North Anatolian Fault [PDF]

open access: yes, 2011
This research was funded by the European Union in the framework of the REL.I.E.F. (Reliable Information on Earthquake Faulting) project (EVG1‐CT‐2002‐00069).

Tremor bands sweep Cascadia [PDF]

open access: yesGeophysical Research Letters, 2010
During the slow slip events in Cascadia and Japan, a well‐documented feature of nonvolcanic tremor (NVT) is its puzzling slow along‐strike migration. But the cause, possible implications, and underlying physics of this long‐term tremor migration and its relationship with slow slip remain elusive.
