How do tsunamis form?

Answer 1

When kids jump up and down in the water.

Answer 2

Tsunamis form from an underwater disturbance such as an earthquake or landslide. If the level of the sea bed changes drastically, it vertically displaces the water above it. That water has to go somewhere, so it washes outward from the site of the disturbance, carrying with it the energy that caused it in the first place. The energy continues to spread from the epicenter until it reaches land. There, the wave slows down, but it also gathers height. An incoming tsunami would look like a very rapidly rising tide, except the water would continue to rise far beyond the normal limits of high tide. Because of their resemblance to rapid incoming tides, many people mistakenly refer to tsunamis as "tidal waves". True tidal waves, however, are a completely different phenomenon unrelated to tsunamis.

Mega-tsunamis can form from an extremely violent event, such as a large meteor impact or an underwater volcanic explosion. Strangely enough, however, megatsunamis are generally a much more localized event; the disturbance greatly upsets water in the immediate vicinity but does not affect shorelines far away. Regular tsunamis, on the other hand, can travel across oceans, as did the Indian Ocean tsunami in 2004.

Answer 3

Most tsunami occur when there is a seismic shift underwater. Some also for as a result of a landslide that comes into contact with the ocean. some also form as a result of a volcanic eruption underwater. an even rarer occurrence is impact from an asteroid or meteor. This is very rare, but these tsunamis may be the most massive formed. If there happened to be a meteor strike in lake michigan, then yes there could be a significant tsunami formed. but the chances of a meteor hitting a lake is probably slim.

Answer 4

tsunamis can form several different ways: 1. An underwater earthquake 2. An underwater volcanic eruption. 3. A land slide that falls into a body of water 4. (The most unusual) A meteor impact

Answer 5

Tsunami ia tidal wave generated by an under-water upheaval of earth's crust(usually an earthquake deep inside the sea bottom).Such a wave moves out in all directions from the point of origin and is capable of causing great destruction on arrival at a coast.This wave travels under the sea surface unnoticed till it arrives near a coast.

Answer 6

A big earthquake under the ocean can cause a tsunami.

Answer 7

Underwater earthquakes cause a sudden jolt in the ocean level and a wave is sent thousands of miles until it encounters land with disastrous results.

Answer 8

Underwater Earthquakes, and Godzilla

Answer 9

it is something along the lines of an uderwater earth quake and that causes a big wave to come up?

Answer 10

earth shifting under water
