Meaning of Tsunami

What is Tsunami:

Tsunami, also known as a tidal wave, is a large wave that forms due to a volcanic explosion or an earthquake and moves at high speed across the surface of the sea. Tsunamis have enormous destructive power and gain strength when they reach the Coastal Region, forming waves more than 30 meters high.

The word tsunami is of Japanese origin, tsu means "port" and namis expresses “waves”, therefore, waves from the port, tsunamis not necessarily occur in the port but can be anywhere on the coast, especially in the Pacific and Indian Oceans, as well as in the Mediterranean Sea.

Despite how difficult it is to predict when a tsunami may occur, some countries with higher incidences and risks of suffering these phenomena are: Chile, the United States, Japan, Mexico, Ecuador, they have an alert center although it is not always possible to have the Certainty when it will happen does allow us to calculate the epicenter of a large underwater earthquake and the time it may take for a tsunami to arrive. To facilitate prevention, it is possible to use underwater sensors, radio telemetry, satellite, among other means to try to measure the behavior of waves and sizes.

Generally, the waves do not affect a single place, they move according to the sea currents, such as: the earthquake in Chile in 1960, it produced a tsunami that killed approximately 5000 people and 14 hours later it reached Hawaii where it killed more people and 9 hours later it arrived in Japan causing more deaths. Also, in 2004 in Indonesia, 11 countries suffered the ravages of the tsunami, such as: India, Indonesia, Thailand, Sri Lanka, among others.
