A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.

A Caribbean-wide tsunami warning system was planned to be instituted by the year 2010, by representatives of Caribbean nations who met in Panama City in March 2008. Panama's last major tsunami killed 4,500 people in 1882. [7] Barbados has said it will review or test its tsunami protocol in February 2010 as a regional pilot. [8] [needs update]
National Oceanic and Atmospheric Administration's NOAA have placed Deep-ocean Assessment and Reporting of Tsunami stations in particular areas, areas with a history of generating large tsunamis, to be completely positive that the detection of tsunamis is to be as fast as possible. The year of 2001 was the completion of the first six tsunami ...
People watch the ocean after a powerful earthquake struck off the coast near Ocean Beach, in San Francisco, California, U.S., December 5, 2024. The word tsunami comes from the Japanese for "harbor ...
People living at a further distance from the epicenter and the detection point may be alerted before they are reached by the damaging waves of the earthquake. People can take part in the project by installing the Android application "Earthquake Network" on their smart phones. The app requires the phone to receive the alerts.
The Deep-ocean Assessment and Reporting of Tsunamis (DART® II) tsunami buoy.. The NOAA Center for Tsunami Research (NCTR), [1] located at the Pacific Marine Environmental Laboratory (PMEL) in Seattle, Washington, performs research in support of tsunami forecast models to increase the speed and accuracy of operational forecasts and warnings, tsunami inundation models to predict tsunami impacts ...
A 650-foot tsunami in Greenland was the result of melting glacial ice that caused a landslide. The waves it created bounced back and forth for nine days.
Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.
