Tsunami Safety Rules

Warning 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.
Warning Not all large earthquakes cause tsunamis, but many do. If the quake is located near or directly under the ocean, the probability of a tsunami increases. When you hear that an earthquake has occurred under the ocean or coastline regions, prepare for a tsunami emergency.
Warning Tsunamis can occur at any time, day or night. They can travel up rivers and streams that lead to the ocean.
Warning A tsunami is not a single wave, but a series of waves. The largest wave may occur several hours after arrival. Stay out of danger until an "ALL CLEAR" is issued by a competent authority.
Warning Approaching tsunamis are sometimes heralded by noticeable rise or fall of coastal waters. This is nature's tsunami warning and should be heeded.
Warning Approaching large tsunamis are usually accompanied by a loud roar that sounds like a train or aircraft. If a tsunami arrives at night when you can not see the ocean, this is also nature's tsunami warning and should be heeded.
Warning A small tsunami at one beach can be a giant a few miles away. Don't let the modest size of one make you lose respect for all.
Warning Never go down to the beach to watch for a tsunami!
Tsunamis can move faster than a person can run!
Warning 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.
Warning 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.
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.
Warning If you are on a boat or ship, weather and time-permitting, move your vessel to deeper water (at least 150 feet). If it is the case that there is concurrent severe weather, it may may safer to leave the boat at the pier and physically move to higher ground.
Warning Damaging wave activity and unpredictable currents can effect harbor conditions for a period of time after the tsunami's initial impact. Be sure conditions are safe before you return your boat or ship to the harbor.
Warning 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.
