Volcanic activity alone can trigger major earthquakes of significant magnitude
Is it true that volcanic activity alone can trigger major earthquakes of significant magnitude?
Yes. Multiple studies demonstrate that volcanic activity, including magma reservoir inflation and subterranean dyke intrusions, significantly alters crustal stress fields and is fully capable of triggering major earthquakes.
Verdict: SUPPORTED · 4 sources for, 0 against · Last checked
The retrieved literature consistently supports the premise that volcanic processes (magma accumulation, movement, and reservoir inflation) alter local stress fields and cause substantial volcano-tectonic earthquakes, matching the claim.
