Tsunami Awareness And Preparedness
A tsunami is a series of potentially dangerous and destructive ocean waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite.
The recent February 27, 2010 earthquake off the Chilean coast generated tsunami waves and triggered a Tsunami Advisory for San Diego County and the entire California coast. The tsunami waves reached the coast of San Diego in the afternoon, causing perceptible and rapid tidal "draw backs" and surges, and unusual currents. While San Diego County did not experience significant inundation or damage as a result of these waves, this recent event serves as a reminder that tsunamis are a threat to the San Diego region. Please refer to the following resources and websites for more information about tsunamis, and for ways to prepare for, and keep safe from, tsunami dangers.
