Seismic symphonies of minor earthquakes may affect grand movements on major faults.

It’s called the Cascadia Subduction Zone. 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 ...

The vertical fault vents the fluids from the plate boundary – the megathrust fault where the tectonic plates meet – to the seafloor. At the plate boundary, liquid acts like a lubricant – and ...

Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images reveal features of the fault ...

For decades, scientists have warned about the potential of the Cascadia Subduction Zone, a megathrust fault that runs offshore along the coast from northern Vancouver Island to Cape Mendocino ...

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 ...

Here, the Pacific Ocean floor is subducting under North America – and when the fault periodically locks and releases, it can unleash devastating megathrust earthquakes and record-breaking waves.

The Cascadia Subduction Zone, a 700-mile-long megathrust fault where the Juan de Fuca Plate dives beneath North America, has a well-documented history of “great earthquakes” events of ...

It’s called the Cascadia Subduction Zone. 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 ...
