← GeographyWhich condition causes increased earthquake risk within strike-slip fault zones?
A)Creep rates fall below average✓
B)Increased rate of sediment deposition
C)Decreased pore pressure in fault rocks
D)Elevated regional groundwater extraction
💡 Explanation
Decreased creep rate elevates earthquake risk because it promotes elastic strain accumulation rather than steady sliding, therefore stress builds up until brittle failure occurs rather than continuously releasing via aseismic slip.
