Some of the world’s largest earthquakes and tsunamis have originated from the Cascadia Subduction Zone, a 1,127-kilometer (700-mile) stretch that runs from northern California up to British ...

The megathrust earthquake takes place due to the build up strain. The recurrence time of a megathrust earthquake heavily varies from one subduction zone to another. For instance, as many as 13 ...

FEMA estimates a Cascadia megathrust quake could result in tens of billions of dollars in damage and potentially 10,000 fatalities.

The sea change in megathrust earthquake and tsunami awareness came nearly five years after the 300th Cascadia anniversary when over 900 miles of the Sumatra-Andamans plate boundary ruptured in the ...

- With the Cascadia megathrust earthquake likely to hit the Northwest US in the next handful of decades, and the San Andrea's fault keeping Californians worrying about earthquake danger, it's time ...

Unlike other subduction zones on Earth, Cascadia presently experiences low levels of seismicity and has not generated a megathrust earthquake since January 26, 1700.

The boundary between the two is known as the megathrust, or the Cascadia subduction zone, fault.

Japan’s new earthquake-detection network lengthens warning times, and researchers in Wales have harnessed nuclear blast detectors to gauge tsunami risks. But the U.S. lags in monitoring the massive Ca ...

The Cascadia Subduction Zone is a megathrust fault or the meeting of two tectonic plates. The Juan de Fuca plate is being forced under the North American plate at a convergent boundary.

The Cascadia Subduction Zone is a megathrust fault or the meeting of two tectonic plates. The Juan de Fuca plate is being forced under the North American plate at a convergent boundary.

Cascadia megathrust earthquakes are caused by the Cascadia Subduction Zone that sits about 40 miles off the coast of the Pacific Northwest, where the edge of one tectonic plate is being slowly ...
