Current early warning systems for tsunamis leave little time for coastal communities to prepare, but a warning system based on the magnetic fields the waves generate could sound the alarm earlier
International Federation of Red Cross and Red Crescent Societies
Usually, we use pressure gauges on the sea floor to tell us when a tsunami is moving over the sensors. But these pressure changes only tell usafter it has passed the sensors. Lin and his team instead used a set of sensors in the south Pacific Ocean to measure magnetic field and sea level change simultaneously for the two tsunamis in that area in 2009 and 2010. They found that the tsunamis were indeed preceded by changes in the magnetic field in the water.
