Which mechanism generates tsunamis after significant seafloor displacement?

💡 Explanation

Tsunamis often arise from seafloor displacement caused by earthquakes; elastic rebound on a thrust fault rapidlyuplifts/subsides portions of the seafloor. This movement displaces a large volume of water, therefore triggering the tsunami, rather than other phenomena like purely horizontal strike motions.
