MORE than a quarter of a million Californians live in coastal areas that could be hit by devastating floods from a major tsunami in the quake-prone US state, a new study says.
The US Geological Survey study, published to mark Tsunami Awareness Week, says tidal waves of eight meters or more could hit northern California following a quake of magnitude 8 or more from a well-known tectonic fault line.
"The tragic loss of life and property damage associated with recent catastrophic tsunamis has raised global awareness of tsunami hazards," the report said, listing the 2004 Indian Ocean and 2011 Japan tsunamis among others.
"Historical and geologic evidence indicate that the California coast has experienced similar large-magnitude tsunamis (and) is susceptible to tsunamis generated by multiple sources," including quakes far away or nearby.
The 60-page report, issued by the California Emergency Management Agency (EMA), included detailed maps showing the most vulnerable coastline areas, from San Diego in the south to Los Angeles and Oakland, near San Francisco.
Crescent City, about 560 kilometers north of San Francisco, was among the worst hit places in California from the Japan tsunami, with boats tossed on top of each other in the harbor, and one death.
