Research: Major fault near reactors links to 2nd crack

LOS ANGELES (AP) - Research has found that an earthquake fault near California's Diablo Canyon nuclear power plant is linked to another fault farther north, potentially making it capable of stronger shaking.

Sophisticated seafloor mapping led by federal agencies has determined what scientists speculated, that the Hosgri fault 3 miles from Diablo Canyon is connected to the neighboring San Gregorio fault.

The U.S. Geological Survey's Sam Johnson says it's not yet known whether the 250-mile strand might have breaks that could limit a full rupture during an earthquake.

Scientists advising owner Pacific Gas and Electric Co. have evaluated a potential rupture on the Hosgri fault linked with other cracks, including the San Gregorio fault.

They found the prospect of that occurring is extremely unlikely, and critical plant equipment could withstand potential additional stress.
