2 types of tsunami
Tsunami "Wave Train" Many people have the mistaken belief that tsunamis are single waves. They are not. Instead tsunamis are "wave trains" consisting of multiple waves. The chart on this page is a tidal gauge record from Onagawa, Japan beginning at the time of the 1960 Chile earthquake.
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.

The most common cause of a tsunami is sea floor uplift associated with an earthquake. Tsunamis are also triggered by landslides into or under the water surface, and can be generated by volcanic activity and meteorite impacts. Tsunamis range in size from inches to over a hundred feet.
Earthquakes generally occur on three types of faults: normal, strike-slip, and reverse (or thrust). Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults.
Large tsunamis are significant threats to human health, property, infrastructure, resources, and economies. Effects can be long-lasting, and felt far beyond the coastline. Tsunamis typically cause the most severe damage and casualties near their source, where there is little time for warning.
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.'

A classic tsunami wave occurs when the tectonic plates beneath the ocean slip during an earthquake. The physical shift of the plates force water up and above the average sea level by a few meters. This then gets transferred into horizontal energy across the ocean's surface. From a single tectonic plate slip, waves radiate outwards in all

The three types of tsunamis are: Local Tsunami-It is a type of tsunami that covers an area of 100km or less. The time duration of this tsunami is less Regional Tsunami-The tsunami which causes destruction in the region covering an area of 1000km of its source is known as Distant Tsunami-The
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.
There are three distinct types of tsunami. The type you encounter depends on the distance you are from the place where it is generated. Distant tsunami: Are generated from a long way away, such as from across the Pacific in Chile. In this case, we will have more than three hours warning time for New Zealand.
