← GeographyWhich crustal deformation occurs when a subducting oceanic plate's asperities overcome resistance along the plate interface?
A)Episodic tremor and slip (ETS) events✓
B)Formation of forearc basins via extension
C)Development of transform faults by shear
D)Crustal thinning through isostatic rebound
💡 Explanation
When asperities on a subducting plate overcome frictional resistance, episodic tremor and slip events (ETS) occur because accumulated elastic strain is rapidly released as slow-slip earthquakes accompanied by tectonic tremor. Therefore ETS occurs, rather than basin formation, transform fault generation, or crustal thinning which involve other mechanisms.
