← GeographyWhich consequence results when a megathrust fault asperities rupture?
A)Formation of island arc volcanism
B)Increased frequency of aftershocks
C)Widespread coastal subsidence occurs✓
D)Decreased lithospheric plate temperatures develop
💡 Explanation
Megathrust asperities resisting tectonic stress cause the fault to lock; when this locking fails, elastic rebound occurs, therefore coastal subsidence occurs rather than volcanism. The mechanism is the release of stored elastic energy.
