The timing and location of such megathrust earthquakes depend on factors such as the shape, roughness, composition, and fluid content of the fault. Phys.org Story by Rebecca Owen ...

It’s notorious for its megathrust earthquakes, powerful seismic events that occur where one tectonic plate is forced beneath ...

Megathrust earthquakes are the most powerful type of earthquake, occurring at subduction zones -- where one tectonic plate is pushed beneath another. By contrast, slow slip events (SSEs) release ...

The U.S. Geological Survey says 13 temblors of magnitude 7 or more have hit coastal Chile since 1973. The latest quake occurred about 140 miles north of the largest earthquake ever recorded, a ...

Tremor occurs on megathrusts under conditions of near-lithostatic pore-fluid pressures and extremely weakened shear strengths. Although metamorphic reactions in the slab liberate large amounts of ...

The key to forecasting deadly megathrust earthquakes. THE force can twist the earth like a piece of ‘elastic’ with devastating consequences.

Analyses of Teotihuacan's three major pyramids show that the city was shaken by multiple catastrophic earthquakes — and this may have led to its demise.

Map of the epicenter of six earthquakes that shook the Mentawai-Siberut megathrust zone segment throughout early Sunday morning until morning, April 23, 2023. Its strengths ranged from M5.9 to the ...

A massive megathrust earthquake off the coast of B.C. — along with a tsunami — is a near certainty, experts say, but nailing down when it will hit is impossible to predict. It could be ...
