Precautionary Measures to Follow When a Tsunami Threatens. A tsunami can injure or kill thousands of people as well as buildings and infrastructure may be damaged and eradicated when waves enter or leave. A tsunami is a sequence of substantial ocean waves causing underwater land sliding, earthquakes, asteroids and volcanic eruptions. The tsunami can travel in between the speed of 15 miles to 35 miles per hour with up to 100 feet high waves. That causes floods, power, and disrupts transport, communications and the supply of water. There are tsunamis on the U.S. shores everywhere. The most dangerous coastline is bordering the Pacific Ocean or in the Caribbean.
Protect yourself against an earthquake first and foremost. Please ensure that you reach the heights as far inland as possible and are alert to tsunami indications, like sudden increase or drainage of the water in the ocean. Also, listen to emergency information and emergency SMS alert. Do not wait for any further for a tsunami or obtain an official tsunami notice - just leave instantly when you see natural indications of the tsunami. And when you are on a ship, go out to the sea with immediate effects.
You should learn about the danger of tsunami if you frequently visit coastal areas or live nearby. Some risk communities have maps with regions and routes for evacuation. You should ask about community plans if you are a regular visitor. Also, learn about the indications of a possible tsunami, like an earthquake, the usual behavior of the ocean or a loud sea roar, like the sudden rising or wall of water, or immediate ocean floor drainage. Get enough knowledge about the evacuation plans and exercise of your society and map your paths from work or home.
Develop a family communication emergency plan with a non-state contact. Plan a particular place where you can meet when you are separated. Don't forget to register for the warning system of your community.
The NOAA (National Oceanic and Atmospheric Administration) and EAS (Emergency Alert System) provide emergency alerts. Besides, some government departments do use different tools of software such as SMS broadcaster machine to alert the people as well. Consider the National Flood Insurance Program (NFIP) for earthquake insurance and flood insurance policy. The insurance of the standard homeowner, however, does not cover the damage of the earthquake and flood.
If there are an earthquake and tsunami, make sure you protect yourself properly against the shock. Put your arms in the head and neck and fall into the knees and hands. It's better to hold on any sturdy furniture until the earthquake stops. Moreover, only crawl when the cover is better, but not in the region with more debris. If there is a tsunami SMS warning or any natural sign, move with immediate effects to a safe place as high as possible. Do listen to the officials but waiting for the tsunami warning can lead to catastrophic consequences. Therefore, do not delay and evacuate instantly.
What to do if you are away from the tsunami risk area and still get a warning message? Well, in that case, you should not move and stay where you are unless you are told by the authorities to move. If you're told by the officials to move, leave instantly. Routes for evacuation are often marked with an arrow by a wave towards higher ground. Then grab something floating like a raft, a tree trunk or a gate if you are in the water. And if you go into a ship or boat, face the waves and go out to the ocean.
