When does a tsunami apper?

Answer 1

A tsunami typically occurs following significant underwater disturbances, such as earthquakes, volcanic eruptions, or landslides, which displace large volumes of water. The most common cause is tectonic plate movements that lead to seismic activity. When the seafloor shifts abruptly, it generates waves that can travel across entire ocean basins at high speeds. As these waves approach shallow coastal areas, they can increase in height, resulting in potentially devastating impacts on shorelines.
