How destructive is the tsunami, and what forces formed it?

The destructive power of the tsunami is quite great, which can set off huge waves as high as tens of meters and flood into coastal cities and island countries. A tsunami can cause hundreds of thousands of casualties, destroy a large number of houses, cars and infrastructure, and cause huge losses to human life and property. Moreover, plagues are prone to occur after disasters, causing secondary casualties of human beings. The main driving force for the formation of tsunami comes from the huge dynamic waves generated during the earthquake. Under the impetus of seismic dynamic waves, seawater will form waves of unstoppable tsunamis. In addition, volcanic eruptions and extreme typhoon weather will also form a powerful tsunami.

The destructive power of the tsunami is quite strong, and it is not weaker than the earthquake in many cases. Take the Indian Ocean tsunami in 2004 as an example. At that time, a 9.3-magnitude earthquake occurred on the seabed in northern Sumatra. The dynamic waves generated by the earthquake gave birth to huge waves with the height exceeding 10 meter, which attacked many island countries and coastal countries such as India, Thailand, Mauritius, Kenya and Singapore. The total number of victims reached 292,206, which brought profound disasters to mankind.

The formation of tsunamis Large tsunamis are generally caused by geological changes on the seabed, most of which are earthquakes or volcanic eruptions on the seabed, and sometimes extreme weather such as tornadoes and typhoons on the sea surface may also cause tsunamis. When the seabed crust vibrates violently, the seawater will surge upward and around when it is squeezed. This huge surge force will form a huge wave, which will rush to the coast at a speed of 700 to 800 kilometers per hour, thus forming a powerful tsunami and causing serious damage to coastal areas.

The negative impact of the tsunami not only directly destroyed the city, causing human and animal casualties, but also left a great negative impact after the disaster. After the sea receded, the environment was greatly destroyed, and the living environment of animals and plants became very bad. A large number of dead animals should be buried and disinfected in time to avoid the spread of plague.
