Their work will give modelers a sharper view of the possible impacts of a megathrust earthquake there — the term for a quake that occurs in a subduction zone, where one tectonic plate is thrust ...

The Cascadia fault, where the Juan de Fuca plate slips beneath the North American plate, is capable of producing megathrust earthquakes. These events not only trigger devastating tsunamis ...

In a new study published in Nature Geoscience, researchers from The University of New Mexico and Nanyang Technological University provide evidence that so-called megathrust earthquakes beneath ...

The most destructive Cascadian earthquakes are likely to slam offshore of Washington state and Vancouver Island, new data reveal. The Cascadia megathrust is a massive fault thought capable of ...

Subduction zone faults build stress, and a so-called megathrust earthquake takes place when a locked fault slips and releases that stress. “Megaquake” is a shortened version of the name.

At the interface of these two plates is a massive fault zone called the Nankai megathrust, which hosts earthquakes of magnitude 8 or greater every 100 to 150 years. The most recent such quake ...

Earthquakes of this relatively small size are common in the Pacific Northwest, with most of them occurring out in the ocean. The last big, “megathrust” earthquake in the region, along the 600 ...

Known as a “megathrust earthquake,” the plates shifted by more than 20 meters, releasing enormous energy and causing tsunami waves up to 35 meters high – the height of a 10-story building.
