superquake
Massive seismic event
A superquake is an earthquake of extraordinary magnitude, typically above 9.0 on the Richter scale.
The term emphasizes catastrophic scale—events capable of reshaping coastlines, triggering tsunamis, and causing destruction across vast regions: Scientists warned that the fault line could produce a superquake.
The prefix super- intensifies beyond what "major earthquake" conveys.
