Investigators are trying to determine if Monday's 4.5 magnitude earthquake in the Bay Area is linked to the explosion and fire at the NuStar Energy facility in Crockett. All operations have been suspended and shipments halted at the facility today.
One Chevron firefighter was injured battling the blaze. He was treated and is expected be ok, according to officials.
Firefighters remain at the scene to monitor flare-ups. They are keeping foam blankets over the area of the tanks that burned.
Crews have concerns about the structural integrity of a tank adjacent to the ones that burned in the fire, according to Contra Costa County Fire Protection District spokesman Steve Hill.
After a seven-hour battle, firefighters contained the blaze at the energy facility last night. Two tanks, one of which collapsed, caught fire sending large plumes of black smoke into the air that could be seen in the area and in other parts of the Bay Area. The fire broke out before 2 p.m. yesterday.
