Which outcome occurs when increased pore fluid pressure reduces effective stress on tectonic plates near the San Andreas fault?

A)Induced earthquake slip tendency increases
B)Aseismic creep rate decreases abruptly
C)Fault gouge cohesion is significantly enhanced
D)Mantle upwelling cools surrounding rocks

💡 Explanation

Reduced effective stress increases the likelihood of fault slip because it diminishes the frictional resistance opposing tectonic forces; therefore, induced earthquake slip tendency increases rather than aseismic creep slowing or gouge cohesion strengthening in surrounding areas.
