Large waves in the seas and oceans occur as a result of geological processes causing environmental disasters called.

Large waves resulting from geographic processes are called tsunamis. Most often, the causes of their occurrence are underwater earthquakes or sudden movements of underwater lithospheric plates. The most active part of the planet, where tsunamis often occur, is the Pacific Ocean.

These waves are not only very high, but also have a great length, therefore, when they hit the shore, they can cause catastrophic destruction over vast territories. The most powerful tsunami in recent years was recorded in 2004.
