Which outcome occurs when lithospheric plates subduct irregularly?

A)Episodic tremor and slip events
B)Increased mantle plume formation
C)Rapid seafloor methane hydrate release
D)Widespread continental crust rifting

💡 Explanation

Episodic tremor and slip (ETS) can occur because irregular subduction causes varying stress accumulation at the plate interface, which is then released as slow-slip events accompanied tremors; therefore, ETS is the outcome, rather than plume formation which relates to mantle convection.
