WebA tsunami watch goes into effect if a center detects an earthquake of magnitude 7.5 or higher. Civil defense agencies are then notified, and data from tidal gauge stations are closely monitored. If a threatening tsunami passes through and sets off the gauge stations, a tsunami warning issues to all potentially affected areas. WebStrong ground shaking from an earthquake is the natural warning that a tsunami might be coming. If you are on the beach or in a harbor and feel an earthquake, immediately move inland or go to high ground. If strong shaking lasts for 20 seconds or more, everyone within the tsunami evacuation area should evacuate as soon as it is safe to do so.
