PMEL Models April 1 Chilean Tsunami Event


Immediately following a magnitude 8.2 earthquake off the coast of Chile on April 1, scientists at PMEL began modeling the event using real-time data from DART® moorings that measured the tsunami 30 minutes after the earthquake struck. They accurately predicted wave arrival times and heights for US coastal communities like Hilo, Hawaii, where a tide gauge recorded a 50 cm tsunami wave.
