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 ...

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 ...

Abstract: The rapid detection and characterization of megathrust earthquakes is a difficult task given their large rupture zone and duration. These events produce very strong ground vibrations in the ...

Last summer, the Japanese weather agency issued a stark megathrust earthquake alert following tremors in parts of western Japan originating from the Hyuga-nada Sea – and where Monday’s ...

The 2010 Mw 8.8 Maule earthquake occurred offshore central Chile and ruptured ∼500 km along the megathrust fault resulting from the oceanic Nazca plate subducting beneath the continental South ...

This quake, known as a subduction megathrust earthquake, can cause massive tsunamis and is associated with seismic activity in the Nankai Trough, an undersea fault line off Japan's Pacific coast.

It concluded the scale of the earthquake was below a moment magnitude scale of 7.0, meaning it did not meet the criteria to issue an advisory with the phrase Megathrust Earthquake Attention. A ...
