← GeographyWhich outcome occurs when a megathrust fault locks near a transform boundary?
A)Increased incidence of shallow earthquakes✓
B)Episodic tremor and slip events
C)Accelerated orogenic uplift rates
D)Enhanced deep mantle convection rates
💡 Explanation
Seismic locking prevents plate motion via creep; therefore, energy accumulates because elastic strain builds faster than it's released via gradual slip, rather than constant smooth sliding, before episodic tremor; this stored energy leads to earthquakes.
