Essentially, they are dynamically equivalent to seismic tsunamis, the only differences being 1) that meteotsunamis lack the transoceanic reach of significant seismic tsunamis, and 2) that the force that displaces the water is sustained over some length of time such that meteotsunamis cannot be modelled as having been caused instantaneously.

Tsunamis. Tsunami refers to a series of enormous waves with long wavelengths and lengthy periods generated in an ocean or a large lake by abrupt vertical movements of the ocean floor that leads to a displacement of a large volume of water within a short time. The name has been derived from the Japanese term 'tsunami,' where 'tsu' means 'port' and 'nami' means 'wave.'

There are two types of tsunami generation: Local tsunami and Far Field or distant tsunami. The coastal areas in the Philippines especially those facing the Pacific Ocean, South China Sea, Sulu Sea and Celebes Sea can be affected by tsunamis that may be generated by local earthquakes.
