Tsunamis are typically characterized by a series of waves that form in the open ocean following a significant underwater disturbance, such as an earthquake, volcanic eruption, or landslide. In the open ocean, these waves are often quite small and may go unnoticed by ships or boats. However, as the tsunami approaches shallow waters and nears the shoreline, it undergoes a process called shoaling, which causes a significant increase in wave height. This means that the waves become much larger and more powerful as they approach the coast, sometimes reaching heights of tens of meters or even more. Therefore, while tsunamis may start as small waves in the open ocean, they become much larger and more destructive near the shore.
