event" at the Diablo Canyon nuclear power plant in California due to a
tsunami warning, which is a normal operating procedure, a spokesman at the

Diablo is located in the middle of the Californian coast, about halfway
between Los Angeles and San Francisco.
San Onofre is on the Southern California coast between Los Angeles and
