This area, called the Cascadia Subduction Zone, hosts a megathrust fault, a place where tectonic plates move against ...

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.

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.

Along this fraught stretch, called the Cascadia Subduction Zone, two pieces of the Earth’s crust slide against each other, building up stresses capable of unleashing a catastrophic 9.0-magnitude ...

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 ...

The new bridge will be earthquake-ready, so crews are digging a 10-foot-wide, 125-foot-deep hole to see how concrete supports react during a simulated seismic event.

Mayor McEnerny-Ogle said "Pressure is mounting for another (Cascadia Subduction Zone) megathrust," one that ... consequences if the tectonic plates shift before we have time to finish planning ...

Many earthquakes in Washington state are linked to the motion of the Juan de Fuca Plate and the North ... This is called the Cascadia Subduction Zone. According to the Washington State Department ...

Aside from the danger they pose, such earthquakes disrupt the slow, long-term changes occurring at subduction zones. The cycle of sudden earthquakes and slow plate movement makes it difficult for ...
