2.Destructiveness: It can lead to a large number of casualties and huge economic losses.

3.Wide-ranging impact:It not only causes casualties and economic losses but also severely affects social stability and people's normal lives.

4.Strong chain reaction:Earthquakes can trigger a series of secondary disasters, such as fires, floods, tsunamis, and so on.

5.Unpredictability:Earthquake forecasting is still in the research stage, and most earthquakes cannot be accurately predicted.

6.Instantaneity:Earthquake disasters occur in a short period, making it difficult for people to organize effective response actions quickly.

A shallow depth large earthquake is a prerequisite. Global typical tsunami statistics analysis shows that only earthquakes above magnitude 7.0 on the Richter scale can potentially cause a tsunami, with a shallow depth usually less than 20-50 kilometers. It is worth noting that large earthquakes often occur in the ocean, but not all deep-sea earthquakes generate tsunamis. The generation of tsunamis is related to the seismic physical mechanisms such as the magnitude of the earthquake, the seismic source mechanism, the depth of the seismic source, and the rupture process. Generally, tsunamis can be triggered by large earthquakes with mainly thrusting (up and down movement), long-lasting rupture processes, and shallow seismic sources.

Secondly, the source area of the tsunami has a large water depth and is mostly found in the deep sea. If the energy released by the earthquake is to be converted into the energy of the wave motion of a huge body of water, then the earthquake must occur in the deep sea, as only the deep sea has a huge body of water. Earthquakes occurring in shallow seas cannot generate tsunamis and often result in ocean swells.

Thirdly, the coastal conditions must have an open and gradually shallowing coastline. For a tsunami to cause damage in the coastal zone, the coastline must be open and have gradually shallowing conditions. When tsunami waves propagate in the open ocean, the wave height is less than 1 meter and does not cause damage. However, when entering shallow waters, the sudden shallowing of the water depth causes the front wave to slow down, while the high-speed water behind continues to surge forward, resulting in a rapid increase in wave height and tremendous destructive power. Especially for those wide outer and narrow inner "triangular bays", the further into the bay, the easier it is for the tsunami waves to intensify and cause greater destruction.

2.Long wavelength:Tsunamis have wavelengths of several hundred kilometers, enabling them to travel thousands of kilometers with minimal energy loss.

Great energy. Tsunamis are not easily detectable in deep ocean waters, but when they reach shallow coastal areas, the wave height increases dramatically, forming a "wall of water" containing enormous energy and causing immense destruction.

3.Fast velocity:Tsunami waves travel very quickly in deep ocean waters, but when they reach shallow coastal areas, the wave height increases rapidly, forming a "wall of water" with tremendous destructive power.

4.Short warning time: Tsunamis originating from earthquakes or other underwater disturbances near coastal regions result in very short or sometimes no warning time for the affected areas, typically only a few minutes or tens of minutes.

5.Wide-reaching impact:Tsunamis can affect regions far from their point of origin; for example, the 2004 Indian Ocean tsunami reached as far as several thousand kilometers away to Sri Lanka.

6.Destructiveness:Tsunamis can destroy coastal structures, inundate land, claim lives, and cause extensive damage to life and property.

Low-lying areas may be submerged.

There may be leakage of hazardous materials and pollutants.

2.Ability to navigate in water.

3.Disinfection and sterilization functions.

Install cameras to enable remote monitoring capabilities. When encountering flooded areas, tracks can flip and deform, releasing airbags to allow floating and driving on the water surface.

Equipped with spray nozzles on the top for spraying disinfectants.
