Объяснение:

The world around us is fraught with many mysteries, and no matter how hard a person tries to subdue it, there is something that remains beyond our control. So, we can't influence the movement of lithospheric plates that provoke underwater earthquakes, which often become the cause of such a terrible natural phenomenon as a tsunami.

Giant waves suddenly burst onto the shore and destroy everything in their path. This occurs in earthquake-prone regions, where fluctuations and tremors of the earth's surface often occur.

Fortunately, tsunamis are rare in our country, and their occurrence is possible only in the Sakhalin region, Kamchatka or Primorye territory. But even such a terrible natural disaster shown on TV can not leave anyone indifferent.
