Which mechanism triggers tsunami formation when a subducting plate rapidly slips?

💡 Explanation

When a subducting plate rapidly slips during an earthquake, vertical displacement of the ocean floor occurs because the overlying water mass is suddenly pushed upwards, creating a wave. Therefore, tsunami formation results, rather than isostatic rebound, liquefaction, or resonance effects, which are secondary.
