Which consequence results when increased pore water pressure affects a continental subduction zone?

A)Shallower fault rupture depth occurs
B)Increased volcanic cinder cone formation
C)Faster buoyant plate upwelling rate
D)Decreased sediment accretionary wedge size

💡 Explanation

Shallower rupture occurs because increased pore water pressure reduces the effective normal stress on the fault, triggering brittle failure via Byerlee's Law. Therefore, faulting initiates at lower depths rather than deeper, more compressional regimes with less water involvement.
