What is tsunami pdf

During a Tsunami Earthquakes are often a precursor to a tsunami. If you feel strong shaking, drop, cover and hold on. Then move to higher ground or, in some communities, a pre-identified safe area. Never go to the beach to watch the waves. A tsunami can move faster than you can run. Follow the evacuation order issued by authorities and evacuate immediately.

Take your animals with you. Move inland to higher ground immediately. Pick areas feet 30 meters above sea level or go as far as 2 miles 3 kilometers inland, away from the coastline. If you cannot get this high or far, go as high or far as you can. Every foot inland or upward may make a difference. Stay away from the beach. Never go down to the beach to watch a tsunami come in. If you can see the wave you are too close to escape it. You should move away immediately.

Save yourself - not your possessions. Remember to help your neighbors who may require special assistance - infants, elderly people, and individuals with access or functional needs. After a Tsunami Return home only after local officials tell you it is safe. A tsunami is a series of waves that may continue for hours. Do not assume that after one wave the danger is over.

The next wave may be larger than the first one. Go to a designated public shelter if you have been told to evacuate or you feel it is unsafe to remain in your home. Avoid disaster areas. Your presence might interfere with emergency response operations and put you at further risk from the residual effects of floods. Stay away from debris in the water; it may pose a safety hazard to people or pets.

Check yourself for injuries and get first aid as needed before helping injured or trapped persons. If someone needs to be rescued, call professionals with the right equipment to help. Many people have been killed or injured trying to rescue others. Help people who require special assistance—infants, elderly people, those without transportation, people with access and functional needs and large families who may need additional help in an emergency situation.

Continue listening to your local radio or television station for the latest updates. Stay out of any building that has water around it. It can be generated by movements along fault zones associated with plate boundaries.

The region where two plates come in contact is a plate boundary, and the way in which one plate moves relative to another determines the type of boundary:. Most strong earthquakes occur in subduction zones where an ocean plate slides under a continental plate or another younger ocean plate.

All earthquakes do not cause tsunamis. There are four conditions necessary for an earthquake to cause a tsunami:. Although relatively infrequent, violent volcanic eruptions represent also impulsive disturbances, which can displace a great volume of water and generate extremely destructive tsunami waves in the immediate source area. One of the largest and most destructive tsunamis ever recorded was generated in August 26, after the explosion and collapse of the volcano of Krakatoa Krakatau , in Indonesia.

This explosion generated waves that reached feet, destroyed coastal towns and villages along the Sunda Strait in both the islands of Java and Sumatra, killing 36, people. Tsunamis caused by extraterrestrial collision i. Scientists have calculated that if a moderately large asteroid, km in diameter, should strike the middle of the large ocean basin such as the Atlantic Ocean, it would produce a tsunami that would travel all the way to the Appalachian Mountains in the upper two-thirds of the United States.

On both sides of the Atlantic, coastal cities would be washed out by such a tsunami. An asteroid kilometers in diameter impacting between the Hawaiian Islands and the West Coast of North America, would produce a tsunami that would wash out the coastal cities on the West coasts of Canada, the U.
