Which outcome occurs when locked fault slip exceeds friction?

💡 Explanation

An earthquake occurs because elastic rebound accumulates stress until it overcomes frictional resistance, causing a sudden release of energy. Therefore, rebound generates shaking, rather than steady creep or forces involving divergent boundaries.
