— James Webb, Mineral Point, Wis. A Chuck DeMets, professor of geophysics at the University of Wisconsin-Madison: Most earthquakes occur when a geological fault, a fracture within the Earth’s crust, ...

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

One of the strongest partnerships we have as emergency managers is with the science community. Without them we could not understand the many hazards that we have and what we need to do to prepare for ...

A deep earthquake in Chile surprised scientists by using heat to grow stronger far underground and cause serious surface ...

This video excerpt from NOVA: "Deadliest Earthquakes" shows how Earth’s crust is made up of rocky slabs, called plates, and how those plates are constantly moving. As molten rock rises from Earth's ...

Within the next 30 years, a highly destructive Nankai Trough megathrust earthquake is predicted to hit southwest Japan. Understanding long-term slow slip events that occur along the plate interface ...
