A megatsunami is a large and extremely destructive tidal wave that is generated by a massive displacement of water, often as a result of geological events such as volcanic eruptions, landslides, or underwater earthquakes. Unlike typical tsunamis, which are usually caused by seismic activity and can travel across entire ocean basins, megatsunamis involve much larger volumes of water being displaced in a very short time frame, leading to waves that can reach extraordinary heights—sometimes hundreds of meters.
