Plate tectonics: new findings fill out the 50-year-old theory that explains Earth's landmasses
Fifty years ago, there was a seismic shift away from the longstanding belief that Earth's continents were permanently stationary.

Super-computer modelling of Earth's crust and upper-mantle suggests that ancient geologic events may have left deep 'scars' that can come to life to play a role in earthquakes, mountain formation, and other ongoing processes ...

The southeastern United States should, by all means, be relatively quiet in terms of seismic activity. It's located in the interior of the North American Plate, far away from plate boundaries where earthquakes usually occur. ...

New geophysical data show that fault slip during the March 2005 magnitude 8.7 (Mw) earthquake off the west coast of northern Sumatra, Indonesia (also referred to as the Simeulue-Nias earthquake), was stopped by the topography ...

When tectonic plates collide, they produce earthquakes like the recent one in Nepal. Researchers at ETH Zurich are providing new ways to explain how and why earthquake supercycles occur in zones where one plate moves under ...

It may seem unlikely that a large earthquake would take place hundreds of kilometers away from a tectonic plate boundary, in areas with low levels of strain on the crust from tectonic motion. But major earthquakes such as ...

The Pacific and North America plate boundary off the coast of British Columbia and southeastern Alaska is a complex system of faults capable of producing very large earthquakes. The recent 2012 Mw 7.8 Haida Gwaii and 2013 ...
