Tsunami’s effects in California offer clues about future
By Abby Sewell, Los Angeles Times
Although the effect of the tsunami was minuscule in California compared with Japan, the scattered damage is providing a rare opportunity to study how the waves work and to help officials better prepare for what could be a far more destructive seismic event along the state’s coast.
Teams of scientists combed the California coast all last week, comparing damage from port to port and harbor to harbor. The result will be a set of recommendations that could give better indications of which areas are most at risk and how to mitigate damage.
“This will be our best data set of response in California from a far-afield tsunami yet,” said Jose Borrero, a tsunami researcher with the consulting firm ASR Limited who traveled the length of the California coast.
The state has already published inundation maps that show which areas are believed to be at risk of flooding in various tsunami scenarios, but the new data will allow for a more detailed understanding.
The California Emergency Management Agency estimates that surges induced by the earthquake in Japan caused $44 million in damage to coastal California, with Crescent City and Santa Cruz being hardest hit. In Crescent City, one man died when he was swept out to sea while attempting to photograph the waves, and much of the town’s harbor was destroyed, crippling the local fishing industry.
