Unlike the mostly even dispersal of energy after a stone falls into a pool of water, the energy emanating from an earthquake travels in a somewhat unpredictable manner. The energy from a quake can't easily penetrate the earth's crust, which is the section of rock up to 18 miles below the surface. Trapped there, a lot of the energy bounces back and then travels horizontally as a surface wave for thousands of miles, Dr. Parsons said.wholesale cool gadgets store
To assess whether such waves can set off large, distant quakes, Dr. Parsons and a co-author in the Nature Geoscience paper, Aaron Velasco of the University of Texas at El Paso, Texas, studied a 30-year seismographic record of all possible quakes larger than magnitude 5 that might have been triggered by every quake of magnitude 7 or larger. wholesale Android-Tablets
Their conclusion: "There is not evidence for very large earthquakes promoting other very large earthquakes at a global scale," although big aftershocks can occur around the original rupture.
