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]
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.

Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...
The warnings were put to use on Thursday when people in the northern portion of California were sent tsunami alerts moments after a 7.0 earthquake struck just off the coast of Humboldt county at ...
A 2021 map shows the impact of a tsunami hitting the San Fransisco area - and the devastation it could cause. The map was thrust back into the spotlight Thursday when a 7.0-magnitude earthquake ...

Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the Earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position ...
Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, [1] [a] and particularly "the determination of parameters for the next strong earthquake to occur in a region". [2]
