I really hope this is true but anyway the risk is too big for San Onofre ..

San Onofre nuclear plant can withstand up to 7.0 quake, is protected by a 25-foot tsunami wall, Edison says

Operators of the concrete-domed San Onofre nuclear plant Monday were trying to reassure jittery Southern California residents that the nuclear disaster unfolding in Japan won't happen here.
The 84-acre generating station in the northern corner of San Diego County is built to withstand a magnitude 7.0 earthquake, said Gil Alexander, a spokesman for the generation station's operator, Southern California Edison. That is greater than the 6.5 shaker that scientists predicted could strike the plant before it was built 42 years ago, he said. But it's less than the 8.9 quake that hit Japan last week.
A 25-foot-high "tsunami wall" of reinforced concete was also erected between the plant and the adjacent ocean, a height based on scientists' best estimates of the potential threat, he said. The geological fault most likely to directly threaten San Onofre lies about 5 miles offshore, Alexander said.
The Nuclear Regulatory Commission also sought to allay fears that small releases of radiation from Japan's crippled Fukishima reactors were a threat to the U.S.
Available information indicates that weather conditions have carried any radioactive vapors out to sea and away from the Japanese population. Given the thousands of miles between the two countries, Hawaii, Alaska, the U.S. territories and the U.S. West Coast are not expected to experience any harmful levels of radioactivity, the commission said.
