Ventura County hot spot puzzles experts
A patch of land in Ventura County's section of Los Padres National Forest where the ground recently heated up to 812 degrees continues to puzzle firefighters and geologists after weeks of monitoring.
"It's a thermal anomaly," said Ron Oatman, spokesman for the Ventura County Fire Department.
Firefighters responded to reports of a blaze there a month and a half ago, when observers noticed smoke rising from the parched scrub. But when they arrived, they found no flames.
The hot spot is in an area considered to be an active landslide that has shifted for more than 60 years. Several hundred feet below its cracked surface lie pockets of gas, tar and oil.
King said he suspects cracks along the landslide's slope allow oxygen to enter into the earth and hydrocarbon material to "seep out" of the fine-grain shale. The combination can create underground combustion, he said.
