'Wobble' may precede some great earthquakes, study shows

The land masses of Japan shifted from east to west to east again in the months before the strongest earthquake in the country's recorded history, a 2011 magnitude-9 earthquake that killed more than 15,500 people, new research ...

6.4 magnitude quake leaves one dead in Puerto Rico: media

A strong 6.4 magnitude earthquake that struck south of Puerto Rico early Tuesday killed at least one person, according to local media, as a series of tremors caused widespread damage across the US territory.

Distinguishing earthquake foreshocks and aftershocks

Up to now, there was no way of predicting whether a powerful earthquake was likely to be followed by one of even greater magnitude. But the results of a study recently published in Nature by Laura Gulia and Stefan Wiemer ...

A seismologist present at the discovery of plate tectonics

As a young seismologist in the 1960s, Lynn Sykes made crucial observations of earthquakes under the ocean floors that helped solidify the theory of plate tectonics—the foundation of modern geology. Later, hoping to apply ...

Supercomputing dynamic earthquake rupture models

Some of the world's most powerful earthquakes involve multiple faults, and scientists are using supercomputers to better predict their behavior. Multi-fault earthquakes can span fault systems of tens to hundreds of kilometers, ...
