Tsunamis and Tsunami Hazards

Tsunamis are triggered by earthquakes, volcanic eruptions, submarine landslides, and by onshore landslides

Detailed Description

Tsunami Facts

  • Tsunamis are triggered by earthquakes, volcanic eruptions, submarine landslides, and by onshore landslides in which large volumes of debris fall into the water. All of these triggers can occur in the United States.
  • If a tsunami-causing disturbance occurs close to the coastline, a resulting tsunami can reach coastal communities within minutes.
  • Although many people think of a tsunami as a single, breaking wave, it typically consists of multiple waves that rush ashore like a fast-rising tide with powerful currents. Tsunamis can travel much farther inland than normal waves.
