Japan earthquake research identifies previously unrecognised seismic hazard
Researchers found that returning waves from Japan’s 2011 earthquake can cause tectonic plates near the surface to slip. The finding identifies a previously unrecognised mechanism of seismic hazard.

- Seismologists already knew big earthquakes send waves down to Earth's core and back, but Japan's 2011 quake was the first time those returning waves were shown to actually slip tectonic plates near the surface — a previously unrecognised source of seismic hazard. ↗terradaily.com · Recorded source date: Sep 9, 2026, 2:46 PM UTC
