The Causes of Tsunami 3 Pages 701 Words

Many people were worried about future troubles as the earth began trembling. A wave was suddenly formed, people on the west coast immediately received a warning. What is this? This is a tsunami, an earthquake occurring in the water. The ocean floor suddenly deforms and moves the overlying water from its equilibrium position. A wave is formed when a moving water mass trying to restore its equilibrium state under the influence of gravity. The main factor that determines the initial size of the tsunami is the amount of vertical seabed deformation. The tsunami may also be caused by the landslides of the ocean floor. During the submarine landslide, the equilibrium sea level will change due to the movement of sediment along the ocean floor. The result of this terrible storm is shocking. The cause of the tsunami is due to earthquakes, landslides and volcanic eruptions, which lead to an increase in mortality rate and injury rate.

The tsunami caused by the ocean bottom earthquake is also called seismic wave. Scientists can calculate the location and time of a particular ocean bottom earthquake and predict when the resulting seismic waves will reach the coast. Scientists calculate based on the data provided by seismic instruments. These instruments detect vibrations called seismic waves that are emitted by earthquakes through basement rocks (Phillip). Land earthquakes are very different from underwater earthquakes. The fact that it contains water makes it even more troublesome to deal with this situation. To find an earthquake in the water, it is sometimes impossible, waves may not have warnings, and waves may cause more death and damage than ground vibration.

In addition to earthquakes, similar ground vibrators are also an important part of the cause of the tsunami. A landslide is a slope where a lot of earth and sand falls. Landslides may occur when rainwater and snow melt sinks to the ground at the top of the slope.

Tsunamis are mostly caused by underwater earthquakes. Sometimes a volcano can cause a tsunami. When the water runs out, the tsunami will land. They are up to 500 miles per hour and the tower is up to 98 feet! Sometimes the tsunami is just a few inches! The size of the tsunami depends on the extent of the earthquake and volcanic eruption. The tsunami is mainly explained as the damage of a large amount of liquid. Even though they are irrelevant to the tide, people often call them tides. In most cases, the tsunami occurred in Japan, China, South Korea and other Asian regions. In the Indian Ocean, a tsunami called Indian Christmas Tsunami issued many dead, others injured and Christmas was ruined! Civilians noticed at that moment. Civilians suffer from tragedy. Tsunami has destroyed many people's lives

Outline of the Indian Ocean Tsunami If you would like to read the overview of the Indian Ocean Tsunami, please visit the Indian Ocean Tsunami http://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake Wikipedia website. Summarize the impact of the tsunami by creating a turn that shows the impact of the tsunami on humans and the environment. Please write the word tsunami in the middle of the wheel. Write down the core environment, society, economy, and politics - these will help you summarize the different results. Start with the first sequential result, then create the second and subsequent order results. I will continue to add information as I develop the wheel. Sample results based on Victorian gold discovery are on page 13 of the pdf file at http://www.qrc.org.au/ _ dbase_upl / explore_section_ 03.pdf.
