The beautiful landscapes of western Oregon and Washington—and the geological hazards we live with—are products of the Cascadia Subduction Zone. Sedimentary layers and basalt from the ocean floor are scraped off and uplifted as the Juan de Fuca Plate dives beneath the edge of the continent, forming the Coast Range. Farther inland the top of the descending plate becomes so hot that it dehydrates; the rising water melts rock that rises as magma to form the Cascade volcanoes. Puget Sound in…
An ocean data buoy is alerting to an “event” in the Cascadia Subduction Zone off the west coast of Oregon. This is where a magnitude 9 earthquake hit in According to the data buoy, the water column height (depth) fell sharply within minutes.
The Cascadia Subduction Zone (CSZ) 'megathrust' fault is a Km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino California.It separates the Juan de Fuca and North America plates.

Area of the Cascadia subduction zone, including the Cascade Volcanic Arc (red triangles), site of recurring megathrust earthquakes at average intervals of about 500 years, including the Cascadia Earthquake of USGS
Cascadia subduction zone worse than San Andreas fault
The Really Big One An earthquake will destroy a sizable portion of the coastal Northwest. The question is when. The next full-margin rupture of the Cascadia subduction zone will spell the worst natural disaster in the history of the continent.
MEGATHRUST EQ Cascadia Subduction Zone-BE PREPARED for Destruction
The Cascadia Subduction Zone off the coast of North America spans from northern California to southern British Columbia. This subduction zone can produce earthquakes as large as magnitude 9 and corresponding tsunamis.
A team of international researchers, led by Monash University’s Associate Professor Wouter Schellart, have developed a new global map of subduction zones, illustrating which ones are predicted to be capable of generating giant earthquakes and which.
