11.1: A Tsunami warning is sounded – what should you do?

  • A strong earthquake felt in a low-lying coastal area is a natural warning of possible, immediate danger. Keep calm and quickly move to higher ground away from the coast. 
  • Tsunamis can occur at any time, day or night. They can travel up rivers and streams that lead to the ocean.
  • A tsunami is not a single wave, but a series of waves. Stay out of danger until an “ALL CLEAR” is issued by a competent authority.
  • Approaching tsunamis are sometimes heralded by noticeable rise or fall of coastal waters. This is nature’s tsunami warning and should be heeded.
  • A small tsunami at one beach can be a giant a few miles away. Do not let modest size of one make you lose respect for all.
  • Sooner or later, tsunamis visit every coastline around the ocean.
  • All tsunamis, like hurricanes, are potentially dangerous even though they may not damage every coastline they strike. • Never go down to the beach to watch for a tsunami! • WHEN YOU CAN SEE THE WAVE YOU ARE TOO CLOSE TO ESCAPE.
  • Tsunamis can move faster than a person can run!
  • During a tsunami emergency, your local emergency management office, police, fire and other emergency organizations will try to save your life. Give them your fullest cooperation.
  • Homes and other buildings located in low lying coastal areas are not safe. Do NOT stay in such buildings if there is a tsunami warning.
  • The upper floors of high, multi-story, reinforced concrete hotels can provide refuge if there is no time to quickly move inland or to higher ground.
  • Stay tuned to your local radio, marine radio, NOAA Weather Radio, or television stations during a tsunami emergency – bulletins issued through your local emergency management office and National Weather Service offices can save your life.
