← GeographyLarge earthquakes increase in frequency when the interseismic period ends due to which fault behavior?
A)Elastic Rebound releases accumulated strain✓
B)Creep deformation reduces asperities
C)Thermal weakening resets failure stress
D)Fluid injection promotes fracture healing
💡 Explanation
Elastic Rebound returns a fault to its mean frictional strength because accumulated elastic strain exceeds the fault's strength; therefore, large earthquakes follow rather than gradual release or restrengthening effects from creep or fluid activity.
