A local earthquake may generate tsunami waves that can reach shore in minutes. If you are on the beach or other low-lying area close to the ocean or bay, immediately evacuate by walking to higher ground if:

  • Officials issue a tsunami warning and order evacuations; 
  • You hear the Outdoor Warning System (and it’s not Tuesday at Noon);
  • The earth shakes so much that you can’t stand;
  • Shaking lasts longer than 20 seconds; and/or
  • You notice water receding from the shoreline.
