where do tsunamis occur

The strongest tidal wave registered in Canada so far reached a height of 38 meters. Earthquakes happen when plates move with respect to each other because the friction and stress at the edges of plates prevent them from slipping smoothly at their boundaries. At this Tsunami on 12/04/2007 no losses of human lifes have been registered. They have caused damage and deaths in coastal areas all around the world. Tsunami waves are unlike typical ocean waves generated by wind and storms, and Tsunamis are ocean waves triggered by:Large earthquakes that occur near or under the oceanVolcanic eruptionsSubmarine landslidesOnshore landslides in which large volumes of debris fall into the water Scientists do not use the term "tidal wave" because these waves are not caused by tides. Tsunamis that cause damage or deaths on distant shores (more than 1,000 kilometers, 620 miles, away) occur about twice per decade. According to the National Ocean Service, these geographic events are defined as a series of waves that occur as the result of undersea earthquakes and volcanic eruptions.As these waves travel from the open ocean toward coastal land, they grow taller and taller. A […] Knowledge of the history of tsunamis in your area is a good indicator of what is likely to happen in a future tsunami event. Countries with long coastlines on the Pacific Ocean, such as Japan, Chile, and the United States, are all at risk of being hit by a tsunami. Tsunamis are just long waves — really long waves. In 1700 the fault ruptured, generating an earthquake of around magnitude 9, which triggered a massive tsunami that was destructive even as far as Japan. At this Tsunami on 08/29/1741 a total of 1,607 people have been killed. CASCADIA SUBDUCTION ZONE The Cascadia Fault extends northwards for more than 1,000km along the west coast of North America, from northern California to midway along Vancouver Island in Canada. Tsunamis are most commonly formed from undersea earthquakes that result in a sudden rise or fall of the Earth's crust under the ocean. Tsunamis in Japan In a total of 141 tidal waves classified as a tsunami since 684 a total of 130,974 people died in Japan. U.S. Department of Commerce Gold Medal in 2005 - for research and development leading to the creation of a tsunami forecasting capability U.S. Department of Commerce Gold Medal in 2004 - for the creation and use of a new moored buoy system to provide accurate and timely warning information on tsunamis The strongest tidal wave registered in Japan so far reached a height of 90 meters. See the percentages on the right for the geological events that cause tsunamis. It takes an external force to start a wave, like dropping a rock into a pond or waves blowing across the sea. Where do Tsunamis Happen? Tsunamis therefore occur comparatively often in this country. Tsunamis are some of nature’s most devastating phenomenons. Tsunamis can be generated in all of the world’s oceans, inland seas, and in any large body of water. Tsunamis can happen in any significant body of water but are most common in the Pacific Ocean, where there are loads of underwater earthquakes and volcanoes. Tsunamis in Canada In a total of 11 tidal waves classified as a tsunami since 1903 a total of 45 people died in Canada. Tsunamis are most likely to occur in the Pacific and Indian Ocean regions. Tsunamis do not have a season and do not occur regularly or frequently. 1.6 Where do tsunamis happen? Tsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. Pacific wide tsunamis are a rare phenomenon, occurring every 10-12 years on average. Earthquakes and tsunami generation. However, they do pose a major threat to the coastal populations of the Pacific and other world oceans. The most common cause is earthquakes. Note that 72% of tsunamis are generated by earthquakes. Sound waves, radio waves, even “the wave” in a stadium all have something in common with the waves that move across oceans. Compared to other countries, Tsunamis therefore occur rather rarely.
