← GeographyWhich mechanism significantly alters aftershock frequency following increased magnitude earthquake displacement?
A)Rate and state friction evolution✓
B)Mantle convection reorganization
C)Hydraulic fracturing propagation velocity
D)Chemical weathering erosion threshold
💡 Explanation
Increased stress from displacement triggers rate and state friction evolution, changing frictional properties because this governs aftershock initiation and frequency, therefore aftershocks evolve as friction stabilizes, rather than resulting from fluid or mantle dynamics.
