← GeographyWhich outcome occurs when repeating moderate shear stress oscillations along tectonic faults reaching a critical instability threshold?
A)Aseismic creep acceleration✓
B)Increased geyser eruption frequency
C)Enhanced metamorphic rock formation
D)Reduced soil liquefaction potential
💡 Explanation
Aseismic creep accelerates because transient stress changes induce rate-and-state friction via elastic deformation along faults, encouraging slow slip rather than abrupt rupture. Therefore creep accelerates, rather than triggering seismic events or altering geological processes substantially due to slow movements.
