Which outcome occurs when a glacial moraine destabilizes a fault?

💡 Explanation

Increased seismic activity occurs because isostatic rebound accelerates fault slip via the mechanism of Coulomb stress transfer. When the glacier melts, this reduces normal stress; therefore, increased seismic activity occurs, rather than fault locking from higher friction on the fault plane.
