Which mechanism is triggered when differential stress exceeds static friction along an existing fault line?

💡 Explanation

When differential stress overcomes static friction, elastic rebound occurs because the rocks suddenly slip releasing stored energy as seismic waves. Therefore an earthquake occurs, rather than creep, ductile flow or fracturing which require different stress conditions and material properties.
