SAN LUIS OBISPO — PG&E provided live demonstrations Wednesday (July 27) of how ground-vibrating trucks will conduct advanced seismic tests later this year to gain a better understanding of earthquake faults near the Diablo Canyon Power Plant.
After an afternoon briefing at the PG&E Education Center here, about 50 people who wanted to learn more about the on-shore portion of planned testing donned earplugs and went into the parking lot. They watched as a caravan of four survey trucks emitted vibrations into the ground.
As part of its commitment to seismic safety, PG&E is conducting two-dimensional onshore seismic imaging to analyze the fault zones near the nuclear power plant and the greater San Luis Obispo area.
Last week, PG&E presented plans for off-shore, three-dimensional seismic studies off the San Luis Obispo County coast.
