Tsunami means a tidal wave or sea wave caused by an earthquake. A tsunami itself is a large sea wave that suddenly hits a coastal area and comes quickly. Earthquake activity or volcanoes erupting under the sea cause tsunami waves. Large tsunami waves create flooding and damage when they hit the coastal land.

Tsunamis form when the surface of the seabed rises and falls along a fault during an earthquake. As a result, the balance of the sea is disturbed. The larger the fault, the greater the wave power generated. After an earthquake occurs, a few moments later the sea water will recede. After that, the sea water will return towards the land in the form of large waves. Tsunamis are not only caused by earthquakes, but also by volcanic eruptions at the bottom of the ocean. This causes high movement of sea water and surrounding waters.

Tsunamis are one of the disasters that cause loss and damage to humans. When a tsunami hits a residential area, the greatest damage occurs because the sea water will drag everything in its path. Therefore, in the face of this disaster we must always be vigilant and prepare ourselves.​
