Which outcome occurs when stress overcomes friction along a subduction zone?

💡 Explanation

Seismic waves occur due to the mechanism of elastic rebound; stress builds up, then is suddenly released as the fault slips, because the rock's strength is overcome. This creates seismic waves rather than gradual creep, because creep involves a slow deformation.
