← GeographyWhich geological hazard increases when groundwater extraction accelerates near a transform fault?
A)Induced seismicity from pore pressure change✓
B)Pyroclastic flows from magma decompression
C)Tsunami generation from submarine slides
D)Glacier surges from bedrock uplift
💡 Explanation
When groundwater extraction accelerates, pore pressure decreases because removal of subsurface fluids increases effective stress on surrounding rocks, which can trigger slip along the fault, inducing seismicity. Therefore, induced seismicity significantly increases, rather than pyroclastic flow, tsunami or glacier surge that require different geological triggers.
