Quaking Corners of the Earth

Since Tuesday, November 14, 2007 earthquakes have been occuring in all four corners of the Pacific Ring of Fire. Not typically unusual since the majority of the world's seismic activity occurs here.

However, what is noteworthy is the increasing pattern of quake events that seem to be occuring in sets of two, three or more.

For example, a quake event off the coast of Japan seems to have a "twin" event in Chile. To watch this phenonema, click on the U.S. Geological Survey's map image above. The map lights up with quake activity around the world. Watch for the pattern of near simultaneous quake events. You can also visit the U.S. Geological Survey's recent quake page.
