Fingerprinting Slow Earthquakes

Posted by timothy on Thursday April 23, 2009 @07:33AM from the more-of-an-earthshrug dept.

CarnegieScience writes "The most powerful earthquakes happen at the junction of two converging tectonic plates, where one plate is sliding (or subducting) beneath the other. Now a team of researchers, led by Teh-Ru Alex Song of the Carnegie Institution's Department of Terrestrial Magnetism, has found that an anomalous layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic tremors. The presence of such a layer in similar settings elsewhere could point to other regions of slow quakes."

I'm confused, did I learn the wrong thing from all those old science clips that show Pangaea breaking apart and the Atlantic ocean forms as the Americas separate from Europe/Africa?
