A massive earthquake occurred early this morning (1:34 EST) off the west coast of Chile some 70 miles NNE of the city of Concepcion. The powerful 8.8 magnitude tremor released about 500 times the energy generated by the recent 7.0 earthquake in Haiti. At least 78 people are reported killed, a number which will no doubt rise as information trickles in. Tsunami warnings have been raised across the entire Pacific Basin, including in Hawaii, Australia, and Japan.

Earthquakes are frequent in this area of Chile because it sets on a subduction zone where the Nazca Plate is pushing beneath the South American Plate. The region is also the location of the most powerful earthquake ever recorded on Earth, a 9.5 tremor that struck in 1960.

Here's an interesting map model from NOAA's West Coast and Alaska warning center illustrating the calculated spread of wave energy across the Pacific basin from the Chilean earthquake.
