A tsunami is a series of ocean waves generated by a large and sudden displacement of water, usually caused by underwater earthquakes, volcanic eruptions, landslides, or, in rare cases, meteorite impacts. Tsunamis can travel across entire ocean basins and cause devastating impacts when they reach coastal areas. Here are some key points about tsunamis: 1. Generation: Tsunamis are primarily generated by undersea earthquakes along subduction zones, where one tectonic plate is forced beneath another. When the seafloor is uplifted or displaced during an earthquake, it disturbs the overlying water column, leading to the formation of tsunami waves. Tsunamis can also be triggered by other events like volcanic eruptions that generate significant underwater explosions or landslides that displace large volumes of water. 2. Wave Characteristics: Tsunamis differ from regular ocean waves in several ways. They have much longer wavelengths, which means that the distance between successive wave crests c...
