Tsunami Preparedness (Video)

A tsunami can strike any ocean coast at any time throughout the year. While they don’t happen very often, they pose a major threat to coastal communities. Check out this video for things you can do to prepare. https://youtu.be/x0GX_kc7JZo #TsunamiPrep

If you live, work or play on the coast, you should prepare for a #tsunami. https://youtu.be/x0GX_kc7JZo #TsunamiPrep

Tsunami Dangers

Facebook
A tsunami can be very dangerous to life and property on the coast. It can produce strong and dangerous currents, rapidly flood the land, and cause great destruction. Even small tsunamis can be dangerous. Strong currents can injure and drown swimmers and damage and destroy boats in harbors. weather.gov/safety/tsunami #TsunamiPrep

Prepare for a Tsunami

Facebook
If tsunamis are a threat in your community, you should include tsunami-specific preparations in your emergency plan. Learn the evacuation routes, identify safe places, and practice evacuating. weather.gov/safety/tsunami-before #TsunamiPrep

What is a Tsunami?

Facebook
What is a tsunami? A tsunami is not just one wave, but a series of waves caused by a large and sudden displacement of the ocean. Most tsunamis are caused by undersea earthquakes. There is no season for tsunamis. A tsunami can strike at any time along any coast and can be very dangerous to life and property. Learn more at weather.gov/safety/tsunami. #TsunamiPrep

Know Your Risk

Facebook
Do you live, work or play on the coast? Do you know your community’s tsunami risk? Your community may have identified and mapped tsunami hazard and evacuation zones. Find links to tsunami maps at http://nws.weather.gov/nthmp/maps.html or ask your local/state emergency management office or your local NWS forecast office for more info. #TsunamiPrep

U.S. Tsunami Hazard

Facebook
Did you know the tsunami hazard exists for all coastal U.S. states and territories? The hazard level varies, but given the large number of people who live, work and play on the coast, even where the hazard level is low, the consequences are high. Learn more about the hazard where you spend time: http://nws.weather.gov/nthmp/ushazard.html. #TsunamiPrep

U.S. Tsunami Alerts

Facebook
Official tsunami warnings are broadcast through local radio and tv, marine radio, wireless emergency alerts, NOAA Weather Radio, and NOAA websites. They may also come through outdoor sirens, local officials, text message alerts, and telephone notifications. Learn about the four levels of tsunami alerts for the U.S.: weather.gov/safety/tsunami-alerts. #TsunamiPrep

Tsunami alerts come from many sources like @NOAA websites & NOAA Weather Radio. weather.gov/safety/tsunami-alerts #TsunamiPrep

Natural Tsunami Warnings

Facebook
If a tsunami strikes, there may not be enough time for an official warning, so it is important to understand natural warnings. If you are at the coast and feel a strong or long earthquake, see a sudden rise or fall of the ocean, or hear a loud roar from the ocean, a tsunami may follow. Move quickly to high ground or inland, away from the water. weather.gov/safety/tsunami-before #TsunamiPrep

How to Respond to a Tsunami Warning

Facebook
In the event of a tsunami, some tsunami warnings will be official, others will be natural. Both are equally important. Official tsunami warnings will tell you what to do. Get updates from local radio/tv or your mobile phone. Follow instructions from local officials. weather.gov/safety/tsunami-during #TsunamiPrep

TsunamiReady

Facebook
Communication and education are important parts of the tsunami warning system. Through NOAA’s TsunamiReady program, a voluntary community recognition program, the National Weather Service works with communities to help them minimize the risk posed by tsunamis. Areas of emphasis include risk assessment, planning, education and warning communications. Becoming #TsunamiReady can improve public safety and reduce tsunami losses.

National Tsunami Hazard Mitigation Program

Facebook
Led by NOAA, the National Tsunami Hazard Mitigation Program (NTHMP) works to protect lives and reduce economic losses from tsunamis at the community level. The #NTHMP includes NOAA, FEMA, the USGS, and 28 U.S. states/territories. Through collaboration, coordination, and support to partner states/territories, the NTHMP focuses on three key functions: hazard assessment, warning guidance, and mitigation.

March 11, 2011: Tohoku, Japan Earthquake and Tsunami

Facebook
Large tsunamis, like the one produced by the magnitude 9.1 Tohoku, Japan earthquake on March 11, 2011, can travel across oceans and cause damage on distant shores. In Japan, the earthquake and tsunami displaced more than 500,000 people, caused approximately $243 billion (2017$) in damage, and resulted in a nuclear accident. Most of the 18,453 deaths were attributed to the tsunami. Outside Japan there was very little loss of life due to warnings and evacuations, but in the U.S. there was more than $94 million in damage and one death.

March 27, 1964: Great Alaska Earthquake and Tsunamis

Facebook
NOAA’s National Tsunami Warning Center was established because of the tsunamis produced by an earthquake in Alaska’s Prince William Sound on March 27, 1964 (Alaska time). This is the largest recorded earthquake in U.S. history (magnitude 9.2) and the second largest in world history. The tsunamis devastated coastal communities in Alaska and caused approximately $1 billion (2017$) in damage along the west coasts of the United States and Canada and in Hawaii. More than 130 people died in Alaska, Oregon, and California due to the earthquake and tsunamis. tsunami.gov https://youtu.be/Lac4Zs_CIdw #TsunamiPrep

April 1, 1946: Unimak Island, Alaska Earthquake and Tsunami

Facebook
NOAA’s Pacific Tsunami Warning Center is largely a result of the tsunami produced by the magnitude 8.6 earthquake off Alaska’s Aleutian Islands on April 1, 1946. The tsunami was observed throughout the Pacific. Most of the 167 lives lost and $352 million (2017$) in damage were in Hawaii where wave heights reached 55 feet. tsunami.gov https://youtu.be/8Bi3o1HK0Ks #TsunamiPrep

April 3, 1868: Hawaii Earthquake and Tsunami

NOAA’s Global Historical Tsunami Database has information about tsunami events from 2000 BC to the present. Today in tsunami history, April 3, 1868, a large earthquake off the island of Hawaii generated a tsunami that washed away 108 homes and drowned 47 people on the island.

May 22, 1960: Puerto Montt, Valdivia, Chile Earthquake and Tsunami

Facebook
Most tsunamis are caused by large undersea earthquakes like the one that struck off the coast of southern Chile on May 22, 1960. This quake, the largest ever recorded (magnitude 9.5), produced a tsunami that was observed around the world. Devastation was greatest in Chile where loss of life may have exceeded 5,000. Lives were also lost in Japan (142), Hawaii (61), the Philippines (21), and California (2). Worldwide, damage was estimated at more than $8 billion (2017$). https://youtu.be/oeKewmAoBEM #TsunamiPrep
