Answer:
Option (4)
Explanation:
Tsunamis are usually defined as the large and extensive wave that occurs in the oceans and seas due to the occurrence of an earthquake below the oceans, underwater landscape and other strong volcanic explosions.
They are mostly initiated by earthquakes, and these types of disasters are unpredictable. The movement of seismic waves is responsible for the generation of tsunamis over the ocean water body. The occurrence of tsunamis is somewhat predictable, by observing the changes that occur in terms of the height of sea level. By making these observations, immediate warnings are given, and the coastal areas are vacated at the earliest.
These tsunamis produce larger or smaller waves depending on the magnitude of the earthquake.
Thus, the correct answer is option (4).
