Tsunamis are terrible disasters, but where are they prone to tsunamis?

Tsunami-prone places include the junction of tectonic plates, as well as coastal areas. Japan, for example, is at the junction of tectonic plates, and it is an island country surrounded by the sea, so there are frequent tsunamis. There are also areas with narrow coastlines that are prone to tsunamis in curved areas.

There are also few islands, and the lagoon area is also prone to tsunami.

Tsunamis are prone to occur in places like Japan because it is an island country and is close to the sea, and as the sea level rises, the waves can easily cause tsunamis and endanger the lives of people.

Tsunami prone areas include areas close to the sea, islands, and lagoon areas. Where the continental horizon is narrow and twisted, where the coastal plates meet, and where the coastal areas are relatively low, flat.

Coastal areas at the junction of plates have frequent geological activities and are prone to tsunami; **Volcanic eruptions are likely to occur in areas prone to volcanic eruptions, which indirectly affect the crust of the seabed and cause tsunamis, such as Japan.

Tsunamis are natural disasters that are destructive waves generated by seabed**, volcanic eruptions, submarine landslides or meteorological changes, with waves reaching speeds of up to 700 800 kilometres per hour and crossing the ocean in a matter of hours; The wavelength can reach hundreds of kilometers and can travel thousands of kilometers with little energy loss; In the vast ocean, the wave height is less than one meter, but when it reaches the shallow water area of the coast, the length of the wave slag is shortened and the wave height increases sharply, up to tens of meters, forming the "water zen cluster wall" of He Liang Ying, which contains huge energy.

Tsunamis are mainly controlled by the topography of the seabed, the geometry of the coastline and the characteristics of the waves, and the roaring waves and ice walls repeat every few minutes or tens of minutes, destroying the embankments, flooding the land, and taking life and property, which is extremely destructive. The global tsunami zone is roughly the same as the ** zone. There are about 260 destructive tsunamis recorded worldwide, an average of about 260.

It happens once every six or seven years. Tsunamis in the Pacific Rim accounted for about 80% of the total. The Japanese archipelago and its nearby waters account for about 60% of the tsunami in the Pacific Ocean, and Japan is the country that has suffered the most from the tsunami in the world.

Natural disaster.

According to the query encyclopedia, tsunami, subject: natural disasters and prevention Term: tsunami disaster English: tsunami disaster, tide bore disaster.

Tsunamis are waves with wavelengths of up to hundreds of kilometers caused by activities such as submarine volcanoes, submarine **, and submarine landslides and collapses. In Japanese, the tsunami is called tsunami. Tsunamis travel hundreds of kilometers per hour and typically take a few minutes.

In general, the wave height of the tsunami is very small and the wavelength is very large during the propagation of the vast ocean, so it is not easy for people to detect. However, when it spreads to shallow sea areas, the occurrence can be most concentrated, forming huge waves, rough waves or rough waves; When they reached the shore, the waves rose further and formed a huge wall of water of 10 to 30 meters, destroying the embankment and surging onto the land, engulfing towns, villages, and cultivated land. Immediately after that, the sea water suddenly withdrew, and often poured in again, sometimes repeatedly, causing huge losses of life and property in the coastal area.

A tsunami refers to a huge wave that occurs in the ocean, and it is a marine disaster. The main causes of tsunamis include**, volcanic eruptions, landslides, seabed**, etc. When these events occur, huge amounts of energy are released into the ocean, and tsunamis are created.

The harm caused by the tsunami to humans.

The harm caused by the tsunami to human beings is very great. It can cause the destruction of houses, buildings, and other structures in coastal areas. At the same time, a tsunami can also cause a large number of people** and even deaths.

In addition, the tsunami causes economic losses and destroys infrastructure such as ports in coastal areas.

How to protect against tsunami hazards.

Since the harm of tsunamis is very large, in order to prevent the damage of tsunamis and reduce losses, human beings have put forward many precautionary measures. First of all, residents of the coastline should regularly participate in disaster prevention drills to improve basic self-rescue and mutual rescue skills, as well as escape and self-rescue skills.

In addition, television, newspapers, etc. should timely release relevant information to the public through various forms, such as wave height, tide, wave width, etc., so that the public can understand the tsunami situation in a timely manner and take corresponding protective measures.

How to save yourself in a tsunami.

If we are unfortunate enough to encounter a tsunami, how can we save ourselves? First of all, once you receive a tsunami warning, you should quickly determine your position, enter a safe area from the coastline, or relatively high buildings and other high ground, and try to avoid escaping to the coastline of Haibeihu, which will be more dangerous.

Secondly, when the tide is low, you should evacuate quickly, and once you see a huge wave on the surface of the sea, you should immediately return to a relatively high building or a mountainous area to take refuge, and do not stay near the chart to prevent being swept away by the huge waves.

The impact of the tsunami on the ecological environment.

The tsunami also had a great impact on the ecological environment. It can destroy coral reefs, fish, seagrass and other ecological environments in the ocean, and have a negative impact on the marine ecological balance.

At the same time, tsunamis can also destroy the vegetation and fauna in coastal areas, disrupting the ecological balance of the coast. In addition, a large number of marine organisms washed up on the shore with the tsunami, which will cause a large number of deaths and have a short-term negative impact on the ecological environment.

Conclusion. As a disaster, the tsunami has brought great harm to mankind. We should raise our awareness of prevention, understand common sense and skills, and be fully prepared for our own safety and the safety of our homes.
