Which event develops when seismic moment concentrates near fault asperities?

A)Sudden, high-magnitude earthquake rupture
B)Gradual creep along fault segments
C)Localized metamorphic mineral formation
D)Episodic tremor and slip propagation

💡 Explanation

A high-magnitude earthquake rupture develops due to increased elastic strain energy caused by **stick-slip friction** at asperities. Because segments are locked, strain accumulates, therefore episodic tremor is less likely, rather than initiating creep.
