What are the sequence of events that occurs during a tsunami?

A tsunami typically begins with a significant underwater disturbance, such as an earthquake, volcanic eruption, or landslide, which displaces a large volume of water. This displacement generates a series of waves that travel rapidly across the ocean. As the waves approach shallower coastal waters, their speed decreases, but their height increases dramatically, leading to the characteristic towering waves. Upon reaching the shore, these waves can inundate coastal areas, causing widespread destruction and flooding.
