Geologists map ocean floor to study fault near nuclear plant

Geologists map ocean floor to study fault near nuclear plant: Today a research vessel will finish mapping more than four square miles of ocean floor off Avila Beach so geologists can better understand an earthquake fault near Diablo Canyon nuclear power plant.
The marine research vessel Bluefin of Seattle has spent nearly most of December towing a sophisticated array of instruments in a grid pattern through the waters of San Luis Obispo Bay.
The result will be a detailed map of the southern end of the Shoreline Fault, which runs northwest from the bay, brushing the coastline just off Diablo Canyon.
