Earthquakes can generate tsunamis when the sea floor abruptly deforms and displaces overlying water. Large tectonic earthquakes beneath the sea can displace large masses of water from equilibrium, causing waves as the water attempts to regain balance under gravity's influence. Tsunamis often form when extensive areas of the sea floor are elevated or subside during quakes.

18. How do earthquakes generate tsunamis?
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water. Tectonic earthquakes are a
particular kind of earthquake that are associated with the earth's
crustal deformation; when these earthquakes occur beneath the sea,
the water above the deformed area is displaced from its equilibrium
position. Waves are formed as the displaced water mass, which acts
under the influence of gravity, attempts to regain its equilibrium.
When large areas of the sea floor elevate or subside, a tsunami can be
created
