Late Holocene coseismic subsidence and coincident tsunamis, Southern Cascadia Subduction Zone, Hookton Slough, Wigi (Humboldt Bay), California

, 2004
I investigate evidence of coseismic subsidence in southern Humboldt Bay and the relation of this subsidence to Cascadia subduction zone earthquakes and to earthquakes on the Little Salmon fault, an active upper plate thrust fault that borders Humboldt ...

Shoreline crossing Moho geometry of the Cascadia slab: CascadiaMoho1.0

Seismica
Accurate characterization of subducting slab geometry is fundamental to understanding the distribution of earthquakes, the dynamics of arc volcanism, and the assessment of seismic hazards.

Modeling Surface Mass Load Displacements Along The Cascadia Subduction Zone

, 2018
The Earth’s surface is under constant strain from different mass loads. Surface mass loads, such as the oceans, atmosphere, and continental water reservoirs, exert forces on the elastic solid Earth, inducing crustal deformation.

Development of design spectra for long-duration ground motions from Cascadia subduction earthquakes

, 1998
There is now growing evidence that large-magnitude earthquakes have occurred and could occur again along the Cascadia subduction zone located west of Vancouver Island, Bristish Columbia.

Rezente submarine Mineralbildungen : Abbild geochemischer Prozesse an aktiven Fluidaustrittsstellen im Aleuten- und Cascadia-Akkretionskomplex

, 1998
Subduction zones with accretionary wedges are potential areas for active fluid transport and expulsion. Upward transport of relatively cold fluids is predominately caused by tectonic compression and usually occurs along geologically predefined conduits ...

Developing a Database of Seismic Data Over the Cascadia Subduction Zone

, 2021
An inevitable megathrust earthquake is expected in the Cascadia subduction zone that will affect the population of the coast of southwestern British Columbia and the northwest of the United States. In this active tectonic margin, the Juan de Fuca oceanic

Using Subducting Plate Motion to Constrain Cascadia Slab Geometry and Interface Strength

Geochemistry, Geophysics, Geosystems
Subduction zones are home to multiple geohazards driven by the evolution of the regional tectonics, including earthquakes, volcanic eruptions and landslides.

Revisiting interseismic deformation in Nankai: focusing on slip-deficit accumulation in the ETS zone and comparison with Cascadia

Earth, Planets and Space
Various stress-releasing phenomena, such as episodic tremor and slip (ETS) and low-frequency earthquakes, occur at the downdip seismogenic zone in southwest Japan.
