If an earthquake meets certain criteria for potentially generating a tsunami, the pop-up window and the event page for that earthquake What are tsunamis?
Tsunamis are ocean waves triggered by: Large earthquakes that occur near or under the ocean Volcanic eruptions Submarine landslides Onshore landslides in which large volumes of debris fall into the water Scientists do not use the term "tidal wave" because these waves are not caused by tides.
