About Tsunamis

Tsunamis, sometimes referred to as seismic sea waves or incorrectly as tidal waves, are abnormally large ocean waves that can reach heights of 100 feet tall and travel at speeds of up to 500 miles per hour. They are usually triggered by underground volcanic activity and earthquakes, but can also occur from undersea landslides or even nuclear explosions.

Tsunamis are difficult to detect at sea because they are only a few inches high. As a tsunami approaches land, the height of the wave increases while at the same time, the water at the shoreline recedes.

While tsunamis are difficult to detect, there are systems in place that provide some early indications that one is eminent or on its way. When a tsunami is detected, or if a possible trigger even occurs, a warning is issued to areas impacted by a possible strike.

Types of Tsunami Warnings

Advisory - An earthquake occurred in the Pacific Ocean, which might trigger a tsunami.

Watch - A tsunami was triggered, but is two hours or more travel time away from the area in Watch status.

Warning - A tsunami is most likely on its way that can cause damage; People in the warned area are advised evacuate.

Important Survival Tips for Tsunamis

  • Understand the terms that identify a tsunami hazard: advisory, watch and warning.
  • If an earthquake occurs, listen to your radio for Tsunami warnings.
  • If you notice a dramatic recession of costal water from the shoreline you should seek higher ground inland immediatly.
  • Following a tsunami, move inland and do not return to impacted areas until officials say it is safe.
