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.
