What is a meteotsunami?

Meteotsunamis are large waves that scientists are just beginning to better understand. Unlike tsunamis triggered by seismic activity, meteotsunamis are driven by weather events, such as fast-moving severe thunderstorms, squalls, or other storm fronts with a change in pressure. The storm generates a wave that moves towards the shore, and it is amplified by a shallow continental shelf and inlet, bay, or other coastal feature.
