Meteotsunami floods islands of Mallorca and Menorca, Spain

Meteorological tsunamis or meteotsunamis are rare but hazardous long ocean waves, which have the same frequencies and spatial scales as tsunami waves.

However, they are not related to seismic activity, volcanic explosions or submarine landslides, but to atmospheric forcing: pressure jumps, atmospheric gravity waves, frontal passages, squalls, etc.
