Tsunami DetectorsTsunami Detectors

Deep-ocean tsunami detectors, as depicted in this illustration, are being designed by the U.S. to take the surprise out of tsunami attacks. The detectors depend on sensorsstationed on the seafloor. When one of the instruments senses a tsunami wave overhead, it will send acoustic signals to a buoy at the surface, which will relay the warning via satellite to officials who willsound an alarm.
