Tracking Tsunamis

For some interesting data about the tsunami that was generated by the recent earthquake off the coast of Chile, visit the NOAA Pacific Tsunami Warning web site that details the sequence of advisories and warnings.  Even though Hawaii was fortunately spared the kind of devasting tsunami that came ashore in Indonesia a few years ago, the NOAA site shows that sea level did rise at the locations they measure in Hawaii, in places up to three feet above normal.  Civil defense authorities in Hawaii acted on the tsunami warnings, successfully evacuating everyone from the areas at risk.  While this is the kind of “drill” you’d rather not have, it undoubtedly provided some valuable lessons learned for everyone involved and will hopefully make the response to the next warning even more effective.

New Tools for California Residents

Second-generation maps of tsunami impact zones for the California coastline are now available.  These maps show areas of the coast that would be vulnerable to giant waves generated by an undersea earthquake.  Also, California residents now have a site that they can enter their address and find out potential risks for their area.  For example, if you enter the address for the Regional Medical Library in Los Angeles you will find that they are vulnerable to earthquakes but that they are outside of a tsunami zone.  The site also lists preparedness steps that can be taken to mitigate the impact of identified risks.
