The Cascadia Subduction Zone is capable of generating powerful earthquakes. The study found compact sediments along the coast of Washington and northern Oregon, a result that suggests that the ...

One example of these areas is in the western Pacific, where the presence of a submerged plate should be impossible, as there’s been no subduction zone nearby in recent geologic history.

Oregon scientists are hoping to help the coastal communities survive a major inundation in various ways. One of those is detailed evacuation maps that anyone can access.

Megathrust earthquakes occur when stress at subduction zones is released, causing significant plate slippage. These events disrupt long-term tectonic changes, complicating modeling efforts.

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One ...

Most tsunamis around the Pacific Basin are caused by major displacements of the sea floor during very large subduction zone earthquakes ... America trenches, for example. The thinner and denser ...
