There are two main types of tsunamis: local tsunamis and distant tsunamis. Local tsunamis are relatively small and occur near the source of the earthquake, volcanic eruption, or landslide that generated them. 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 tsunami is not a single wave but a series of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive. Tsunamis are not tidal waves. Tsunami waves
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 The earthquakes that caused these tsunamis are: Prince William Sound, Alaska, 1964, magnitude 9.2; Chile, 1960, magnitude 9.5; Alaska, 1946, magnitude 7.3; Puerto Rico/Mona Rift, 1918, magnitude 7.3 to 7.5; Virgin Islands, 1867, magnitude undetermined; Cascadia, 1700, magnitude 9; and Puget Sound, 900, magnitude 7.5.

Tele-tsunami/Ocean-wide tsunami/Distant tsunami: A tsunami originating from a source, generally more than 1,000 km or more than 3 hours tsunami travel time from the impacted coastline is called an ocean-wide or distant or tele-tsunami.

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. Mimr.
