← GeographyWhich geological outcome characterizes oceanic-continental subduction boundaries near plate locking?
A)Megathrust earthquake rupture initiation✓
B)Abyssal plain sediment accumulation
C)Passive margin thermal subsidence
D)Mid-ocean ridge basalt extrusion
💡 Explanation
Oceanic-continental subduction causes strain accumulation because plate locking temporarily prevents slip; therefore, a megathrust earthquake ensues at the rupture point, rather than gradual creep or volcanic eruption, under specified stress conditions on the fault plane.
