Seismic waves bounced off Earth’s core and shifted Japan after massive 2011 earthquake
Researchers have identified that a seismic wave from the 2011 Japan earthquake reflected off the Earth's core, causing a measurable eastward shift.
📍 Where it landed
Researchers identified that a seismic wave from the 2011 earthquake traveled to Earth’s core before bouncing back to the surface. This process resulted in the eastward shift of Japan by approximately six millimeters.

Where it stands
During the 2011 magnitude-9 earthquake in Japan, seismic waves traveled approximately 2,900 kilometres to the Earth's core. These waves reflected back to the surface within 13 minutes, resulting in an eastward displacement of the country.
Coverage from outlets including Science News, Space Daily, CNN, and Scientific American emphasizes the specific geological mechanism behind this movement. Reports note that the entire country shifted by roughly six millimetres at the moment the reflected waves returned to the surface.
Future reports may clarify the broader implications of this seismic phenomenon for geological modeling. Current coverage does not specify if similar core-reflection events have been documented in other major global earthquakes.
