Tsunami Warning Buoy

Tsunamis are caused when an underwater earthquake causes massive waves which can devastate the coastlines of entire ocean basins, as happened with the 2004 tsunami which affected areas from Somalia to Indonesia.The first early warning systems developed in Hawaii, but it wasn’t until the late twentieth century that today’s tsunami warning system was developed and launched off the northwest coast of the US. Paired with a sensor on the ocean floor that watches for seismic activity, the buoy is the communications hub that transmits tsunami data to an international network and helping give affected populations a few precious minutes to prepare.
