A team of scientists led by the American Hermann Fritz (Hermann Fritz) started work on a kind of tsunami maps, which should contain the most complete information about this dangerous phenomenon.
At the beginning of his research assistants conducted laser scanning the northeastern coast of Japan, which last year hit one of the most powerful tsunami in the country's history. Using terrestrial laser scanners scientists estimate damage caused by the tsunami, and as a consequence — the maximum wave height, which was previously known only approximately.
Also, the wave height was estimated by video taken witnessed the terrible events. As a result, experts have determined that the average rate of outflow of water at the tsunami was nine meters per second — to survive in such conditions is almost impossible.
Based on measurements which are conducted by Fritz and his team in the future may be based plans to evacuate people, the scheme of building coastal areas and other documents governing the livelihoods of the regions in which a high probability of a tsunami.
"The ultimate goal in any case is to save lives — said Fritz. — In order that we can do this, you need to understand what a tsunami, and to determine how to protect themselves from it. For example, to construct a three-dimensional model of the coast and to understand whether the breakwater to reduce the force of the waves. "
The team notes that the results of his research can be applied in almost any country. Currently, Japan is one of the most protected from the tsunami States, but in South East Asia, there is, for example, Indonesia and Thailand, which can be adversely affected by the disaster. In the first place, based on the "map tsunami" will be to develop a system alert after escape from the elements only when a person is informed about it.
The study was conducted by experts from the University of Southern California, the University of Tokyo and the Tokyo University of Marine Science and Technology.
