When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. west coast could shake violently for five ...

Along this fraught stretch, called the Cascadia subduction zone, two pieces of the Earth ... they used the data to construct a comprehensive map of the underwater geology in a study published ...

Subduction zones produce the world's largest earthquakes. These quakes occur when friction between the two plates causes them to become locked, and stress begins to build along the border between them ...

1. Figure 1: Map of the northern Cascadia subduction zone showing the distribution of earthquakes in the subducting Juan de Fuca plate and the locations of seismic cross-sections. Green dashed line ...

Schematic figure of the subduction zone underneath the Kanto region (left) in Japan and the spatial distribution of magnitude 2 to 6 earthquakes on the subduction zone at 60 to 70 kilometers below ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.

"This is the first large scale ocean bottom seismic experiment conducted at an Atlantic subduction zone," said Dr. Catherine ... it now has a new claim to fame in the world of plate tectonics." ...
