A Giant Seismic Wave Bounced Off Earth's Core And May Have Shifted Japan
A new analysis suggests that seismic waves from the 2011 Tōhoku earthquake reflected off Earth's core and may have caused Japan to shift eastward by several millimeters. This discovery provides new insights into how major earthquakes affect the planet's crust.
Why it matters
This research enhances our understanding of seismic wave propagation and the long-term geological impacts of massive earthquakes.
