A tsunami(海啸) is a series of(一系列) huge waves that can cause great destruction(毁灭) when they hit a beach. Most tsunamis are caused by underwater earthquakes, but not all underwater earthquakes cause tsunamis. About 90 percent of all tsunamis take place in the Pacific Ocean, most of them are in Japan. A strong earthquake in the ocean near Japan caused a deadly tsunami on March 11,2011. As of April 25, the number of death had been raised to 14,133, and more than 13,346 people were listed as missing. The word “tsunami” comes from the Japanese word.
Many tsunamis could be found before they hit land with the use of modern technology. If you see the water drawback (后退) quickly and unexpectedly from a beach, run toward higher ground or inland -- there may be a tsunami coming. Also, if you are on the beach and there is an earthquake, it may have caused a tsunami, so run toward higher ground or inland. The first wave in a tsunami is often not the largest; if you experience one unusually-huge wave, go inland quickly -- even bigger waves could be coming soon.
Do you know the story of the "angel(天使) of the beach"? Tilly, A 10-year-old English schoolgirl who saved the lives of hundreds of people in Phuket,Thailand in the Asian Tsunami of 2004 , by warning them a wall of water was about to strike(袭击), after learning about tsunamis in geography class. “Last term geography teacher Andrew Kearney taught us about earthquakes and how they can cause tsunamis,” Tilly said to the reporter.“I was on the beach and the water started to go funny. There were bubbles and the water went out all of a sudden. I recognised what was happening and had a feeling there was going to be a tsunami. I told mummy.”
