- Abstract
The article presents information on oceanic tsunami warning system. Earthquakes are detected within two minutes by seismic monitors all around the country. Seismic information is quickly fed into a computer simulation that contains 100,000 precalculated outcomes for earthquakes of various magnitudes and depths at 4,000 different locations. One minute later, one of six regional centres, staffed around the clock, can disseminate warnings by TV or radio. The Pacific Tsunami Warning Center in Hawaii, a US system consisting of six seafloor pressure sensors, which triggers alarms for Pacific nations is the only oceanic tsunami warning system currently in place.
