Summary
A 2011 earthquake in Japan triggered a seismic wave that bounced off Earth's core and returned, causing the entire country to shift a few millimeters east. This phenomenon, reported in Science, represents the first recorded case of a seismic wave making a round trip to Earth's core and back, setting off fault slips along Japan's plate boundaries. The discovery reveals a previously unrecognized seismic hazard.
