Brawley Zone Earthquake Swarm Erupts

August 27, 2012

Southern California’s Brawley Seismic Zone is expected to continue experiencing hundreds – if not thousands – of small to moderate earthquakes over the coming days as a swarm of temblors shake the region between San Diego and Mexic0. Seismologists say they do not expect the magnitude of the temblors to exceed 5.8, the largest ever [...]

Map of Earthquakes Since 1898

July 1, 2012

A data visualization expert has created a stunning map of the globe depicting all magnitude-4 or higher earthquakes since 1898 (for a total of 203,186 temblors). Each earthquake is connoted by a light, the more intense the hue the more intense the quake’s magnitude. Not surprisingly, the map offers a clear primer on the tectonic [...]

Looming Cascadia Earthquake Sends Tribes to Higher Ground

March 13, 2012

The small coastal community had just quieted for the night when a massive earthquake set the ground pitching and bucking like a wild horse. So great was the shaking that liquification transformed area marches into quicksand that swallowed homes whole. The violent shaking lasted for nearly a minute and when it was done, much of [...]

One Year Later, Megaquake Raises More Questions than it Answers

March 11, 2012

On the one-year anniversary of the modern world’s most powerful earthquake, seismologists, geologists, and other scientists note that the biggest lesson learned from the magnitude-9 Tohoku megaquake may be that we know even less than originally thought. The March 11 earthquake took the world’s most earthquake-savvy nation utterly by surprise. Temblors of that size were [...]
