The Cascadia Subduction Zone is capable of generating "megathrust" earthquakes with magnitudes of 9.0 or higher. Such an event, which last occurred over 300 years ago, could trigger a tsunami ...

January 26 marked the 325th anniversary since the last earthquake struck the Cascadia subduction zone. Centuries later, the ...

Jan. 26, 2025, marks 325 years since the last great earthquake on the Cascadia subduction zone. It’s a time to reflect on what we’ve learned about this largest fault system in the lower 48 states ...

January 26 marked the 325th anniversary since the last earthquake struck the Cascadia Subduction Zone. Centuries later, the ancient quake has left clues for scientists to prepare for the next one.

Major earthquakes in the Pacific Northwest are fairly ... meaning two tectonic plates move horizontally against each other. The offshore Cascadia Subduction Zone is known as a megathrust fault — a ...

and used radiocarbon dating to determine when large or so-called megathrust earthquakes occurred on what is known as the Cascadia subduction zone. "The sediments preserved on the bottom of ...

The Cascadia Subduction Zone, which spans from British Columbia to Northern California, periodically experiences megathrust earthquakes M >8. During these ruptures, the last of which occurred in 1700, ...

The timing and location of such megathrust earthquakes depend on factors such as the shape, roughness, composition, and fluid content of the fault. Aside from the danger they pose, such ...

The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

It’s notorious for its megathrust earthquakes, powerful seismic events that occur where one tectonic plate is forced beneath another, releasing colossal quantities of energy. If the Nankai ...
