Whether you know, that:

In 1964, nearby to Alaska there was an earthquake which has caused a tsunami with waves in height in 3-6 m., destroyed coast in California, Oregon and Washington.

The centre of the prevention of a tsunami in risk zones carefully supervises disorders what can cause a tsunami. When there is a dangerous situation, the centre fixes it and gives out the prevention in case of need. Having seen a photo (tsunami waves, centre work and so forth), you can learn more about it the phenomenon.

It is a little about tsunami work

As we already spoke, from area where there is a tsunami, waves extend in all directions. Coming nearer to coast, the wave is formed, for its sizes the topography of a coastal line and an ocean bottom, often a tsunami can influence come not alone, and "groups" (look tsunami photos).

Any tsunami are potentially dangerous even if they do not cause a damage to coast. The small wave on one beach can mean the huge weights of water approaching on coasts, located nearby.

The earthquake caused by movement of ground breeds, most often causes a tsunami. In case of strong earthquake or the landslip which has occurred close from coast, the first wave from a series can reach a beach within several minutes, even before the prevention will sound. The tsunami leads to human death, the most widespread death - утопление, on the second place there are the traumas incompatible with a life. By the way, attempt to make unusual photos of a tsunami very often leads to death of the unlucky photographer. Apparently on a photo, tsunami waves destroy coastal structures, cause flooding, pollute potable water, destroy gas pipelines and so forth
