A Bird's Eye View of the Chile Earthquake's Energy Distribution
It's easy to think of tsunamis as phenomenon that mimic the behavior of ripples on the surface of water; you toss a stone into a pond and the resulting energy from the splash moves out away from the epicenter in a series of even, concentric circles. But this NOAA energy distribution map from the 8.8 magnitude earthquake in Chile over the weekend tells a different story. Though the tsunami threat wasn't great - the reddest portions of the above map represent only 3-foot-plus waves - you can really see the way the energy pushed out away from the continental shelf, posing the same threat to islands in the mid-Pacific and all the way across the ocean in Asia as it did to nearby coastal regions along South America's northern Pacific coast (though the immediate coastal areas near the epicenter did experience some deadly waves, with the sea coming as far as...
