TSUNAMI PREPAREDNESS SAFETY TIPS
Tsunami Safety Tips courtesy of NOAA, National Weather Service
Everyone, everywhere should know how to be prepared for tsunamis and how to stay safe. This is true for people who live or work near the ocean, as well as anyone who visits. Are you in the Tsunami Zone?
|Tsunamis are among Earth’s most infrequent hazards. But even though tsunamis do not occur very often, and most are small and nondestructive, they pose a major threat to coastal communities, particularly in the Pacific. A tsunami can strike any ocean coast at any time. There is no season for tsunamis. We cannot predict where, when or how destructive the next tsunami will be. However, while tsunamis cannot be prevented, there are things you can do before, during and after a tsunami that could save your life and the lives of your family and friends. Learn about tsunamis and what you can do to keep yourself and your loved ones safe in the event of a tsunami.|
BEFORE A TSUNAMI:
Even though tsunamis happen infrequently, it is still important to prepare for one if you live, work or play on the coast. Many of the things you need to do to prepare for a tsunami are the same as those you need to do to prepare for the other hazards that may impact your community. But some actions are unique to tsunamis since response time may be limited. It is not hard, and it is not expensive.
Here are 5 steps you should take now to help protect yourself and your loved ones in case a tsunami ever strikes your community.
1. Know Your Risk
- Find out if your home, school, workplace or other frequently visited places are in tsunami hazard or evacuation zones and if your community has had tsunamis in the past. Your local emergency management office, your state’s geologic or tsunami hazard website and your local National Weather Service Weather Forecast Office are good resources for information about your risk.
2. Understand the Warnings
There are two ways that you may be warned that a tsunami is coming: official tsunami warnings and natural tsunami warnings. Both are equally important. You may not get both. Be prepared to respond immediately to whatever you hear or see first.
- A tsunami warning will be broadcast through local radio and television, marine radio, wireless emergency alerts, NOAA Weather Radio and official NOAA Government websites such as Tsunami.gov. It may also come through outdoor sirens, local officials, text message alerts and telephone notifications.
- There may not always be time to wait for an official tsunami warning. A natural tsunami warning may your first, best or only warning that a tsunami is on its way. Natural tsunami warnings include strong or long earthquakes, a loud roar (like a train or an airplane) from the ocean, and unusual ocean behavior. The ocean could look like a fast-rising flood or a wall of water. Or, it could drain away suddenly, showing the ocean floor, reefs and fish like a very low, low tide. If you experience any of these warnings, even just one, a tsunami could be coming.
3. Practice All-Hazards Preparedness
- Get a battery-operated NOAA Weather Radio to receive official messages and other hazard information 24 hours a day, 7 days a week.
- Sign up for email and text message alerts from your local emergency management office and make sure your mobile devices are set to receive wireless emergency alerts.
- Make an emergency plan that includes a family communication plan and put together a portable disaster supplies kit that is easily accessible and contains basic items you and your family may need in any emergency. Include your pets in all your preparedness efforts. Since you do not know where you will be when disaster strikes, prepare emergency kits for work and your car, too.
- Meet with your family to discuss the plan and why you need to prepare for a disaster.
- Practice your plan and keep it up to date.
- Be a role model. Share your knowledge and plans with friends and neighbors so they can prepare themselves and their loved ones.
4. Plan for Evacuation
If your home, school, workplace or other frequently visited places are in tsunami hazard or evacuation zones, your emergency plan should include evacuation plans.
- Find out if there are evacuation routes and assembly areas identified for your community. This information may be on a tsunami hazard or evacuation zone map, or ask your local emergency management agency.
- If assembly areas are not identified, plan to evacuate to a safe place that is on high ground or inland (away from the water) and outside the tsunami hazard or evacuation zone. You may need to identify more than one safe place, depending on where you may be when you get a tsunami warning (e.g., home, work, etc.). You should plan to be able to reach your safe place on foot if you can because of possible road damage, closed roads and traffic jams. If you are concerned that you will not be able to reach a safe place in time, ask your local emergency management office about vertical evacuation. Some strong (e.g., reinforced concrete) and tall buildings may be able to provide protection if no other options are available.
- Map out evacuation routes to your safe place(s) from your home, workplace or any other place you visit often that is in a tsunami hazard or evacuation zone.
- Practice walking your evacuation routes, including at night and in bad weather. Familiarity with the routes will make evacuation quicker and easier if you ever need to evacuate for real.
- If you have children that go to school in a tsunami hazard or evacuation zone, ask about the school’s plans for evacuating and keeping the children safe. Learn where the assembly area is and where to pick up your children after the danger has passed.
- If you are visiting an area at risk for a tsunami, find out about local tsunami safety. Your hotel or campground may be able to provide you with tsunami warning and evacuation information. It is important to know this information before a warning is issued. You may not have a lot of time after a warning. You do not want to waste it figuring out what to do.
5. Plan for Safe Boating
If you are on a boat and you get a tsunami warning, your response will depend on the size of the tsunami, the currents it produces, where you are, how much time you have before the first wave arrives and the weather at sea. If you are a boat owner or captain:
- Make sure you have a way to receive tsunami warnings when you are on the water. The U.S. Coast Guard will issue urgent marine information broadcasts on your marine VHF radio’s channel 16. Additional information will be available from NOAA Weather Radio.
- Find out what to do if you get a tsunami warning when you are on a boat in a harbor and what to do if you are at sea. In general, if you are in a harbor, you should plan to leave your boat and move quickly to a safe place on land (high ground or inland, away from the water). If you are at sea, you should plan to move to a safe depth (which varies by region) and stay away from harbors under warning until officials tell you the threat has passed. Your harbormaster, port captain, the U.S. Coast Guard and local and state emergency management offices are the best sources for tsunami safety information and regulations for boaters in your area.
- Make a plan and put together a disaster supplies kit to keep on board your boat. Be aware that shore facilities may be damaged, so if you are at sea during a tsunami, you may not be able to return to the harbor right away. Be prepared to remain at sea for a day or more.
