Aftershocks

I have heard just brief mentions about aftershocks from the quake that caused the tsunamis, but this list of current earthquake activity from the USGS National Earthquake Information Center shows what those places are experiencing--many earthquakes over five and several over six on the Richter scale.

I also learned while exploring this morning that you can get live seismograms of earthquakes around the world on your home computer using the Live Internet Seismic Server, although it looks pretty complicated. Fortunately, the Incorporated Research Institutions for Seismology (IRIS) have already used that data to put up a colorful interactive mapping tool, the Seismic Monitor.     #
