← GeographyWhich outcome occurs when a creeping fault experiences heterogeneous frictional resistance?
A)Episodic tremor and slip (ETS) events✓
B)Continuous aseismic ductile deformation
C)Regular, predictable low magnitude earthquakes
D)Complete cessation of tectonic plate motion
💡 Explanation
Episodic tremor and slip occur because rate-weakening friction patches along the fault will suddenly slip, causing both tremor and slow slip events, therefore ETS characteristics result rather than continuous creep, because resistance heterogeneity prevents continuous stable sliding.
