← GeographyWhich mechanism elevates pore fluid pressure near faults?
A)Dilatancy pumping increases pressure.✓
B)Frictional heating balances stress.
C)Creep reduces effective stress.
D)Seismic waves induce compaction.
💡 Explanation
Dilatancy pumping elevates pore fluid pressure because shear stress causes microcracks, pulling fluid in; therefore, pressure rises, rather than pressure decreasing from stress reduction or seismic influences.
