Why does Japan have so many earthquakes and tsunamis?
A powerful earthquake struck western Japan on New Year's Day, killing dozens of people, destroying homes and triggering fears of greater harm from aftershocks, tsunamis and landslides. Japan sits on top of four major tectonic plates, making it one of the most seismically active countries in the world. "The more plates you have and, more importantly, the more plate boundaries that you have adjacent to or crossing a country like Japan, the more interaction of those plates on which earthquakes occur," said Robert Butler, professor emeritus of geophysics at the University of Arizona. "So more plate boundaries mean more earthquakes."
