A tsunami is a series of waves with a long wavelength and period (time between crests). Time between crests of the wave can vary from a few minutes to over an hour. Tsunamis are often incorrectly called tidal waves; they have no relation to the daily ocean tides. Tsunami (soo-NAH-mee) is a Japanese word meaning harbour wave. Tsunamis can occur at any time of day or night. How are tsunamis generated? : How are tsunamis generated? Tsunamis are generated by any large, impulsive displacement of the sea bed level. Earthquakes generate tsunamis by vertical movement of the sea floor. If the sea floor movement is horizontal, a tsunami is not generated. Earthquakes of M 6.5 are critical for tsunami generation. Tsunamis are also triggered by landslides into or under the water surface, and can be generated by volcanic activity and meteorite impacts. Slide 4: How are tsunamis generated? How often do tsunamis occur? : How often do tsunamis occur? On the average, there are two tsunamis per year somewhere in the world which cause damage near the source. Approximately every 15 years a destructive, Pacific-wide tsunami occurs. The destructive tsunami on Dec 26th, 2004 on the Indian Coast seems to have occurred for the first time in the history. How fast does a tsunami travel? : How fast does a tsunami travel? Tsunami velocity is dependent on the depth of water through which it travels (Velocity equals the square root of water depth h times the gravitational acceleration g, V =g h). Tsunamis travel approximately 700 kmph in 4000 m depth of sea water. In 10 m of water depth the velocity drops to about 36 kmph. How is a tsunami different from a wind-generated wave? : How is a tsunami different from a wind-generated wave? Wind-generated waves usually have periods (time between crests) of 5 to 20 seconds. Tsunami periods are usually between 5 minutes and an hour. Wind-generated waves break as they shoal and lose energy offshore. Tsunamis act more like a flooding wave. A 6 m tsunami is a 6 m rise in sea level. Tsunami Disaster : Tsunami Disaster WHAT TO DO OR NOT TO DO UNDER RISK FROM TSUNAMI : WHAT TO DO OR NOT TO DO UNDER RISK FROM TSUNAMI You should find out if your home, school, workplace, or other frequently visited locations are in tsunami hazard areas. Know the height of your street above sea level and the distance of your street from the coast or other high-risk waters. Evacuation orders may be based on these numbers. Also find out the height above sea level and the distance from the coast of outbuildings that house animals, as well as pastures or corrals. Use a Weather Radio or stay tuned to a local radio or television station to keep informed of local watches and warnings. Talk to your insurance agent. Homeowners' policies may not cover flooding from a tsunami. Ask about the Flood Insurance Program. Protect Your Property : Protect Your Property Make a list of items to bring inside in the event of a tsunami. A list will help you remember anything that can be swept away by tsunami water. Elevate coastal homes. Most tsunami waves are less than 3 meters. Elevating your house will help reduce damage to your property from most tsunamis. Take precautions to prevent flooding. Have an engineer check your home and advise about ways to make it more resistant to tsunami water. These areas are more likely to experience damage from tsunamis, strong winds, or coastal storms. What to Do After a Tsunami : What to Do After a Tsunami You should continue using a Weather Radio or staying tuned to a Coast Guardemergency frequency station or a local radio or television station for updatedemergency information. The Tsunami may have damaged roads, bridges, or other places that may be unsafe. Check yourself for injuries and get first aid if necessary before helping injured ortrapped persons. If someone needs to be rescued, call professionals with the right equipment to help Tsunamis in India : Tsunamis in India During an earthquake in 1881 which had its epicenter near the centre of the Bay of Bengal, Tsunamis were reported. The earthquake of 1941 in Bay of Bengal caused some damage in Andaman region. During the earthquakes of 1819 and 1845 near the Rann of Kutch, there were rapid movements of water into the sea. Further west, in the Persian Gulf, the 1945 Mekran earthquake (magnitude 8.1) generated Tsunami of 12 to 15 metres height. Help people who require special assistance : Help people who require special assistance Avoid disaster areas. Use the telephone only for emergency calls. Stay out of a building if water remains around it. When re-entering buildings or homes, use extreme caution. Look for fire hazards. Check for gas leaks. Look for electrical system damage Check for damage to sewage and water lines. Watch out for wild animals Infants, elderly people, those without transportation, large families who may need additional help in an emergency situation, people with disabilities, and the people who care for them.
