Ground temperatures exceeding 800 degrees (C? F? HOT!) are being recorded at the Los Padres Forest in Ventura County, California. Geologists are uncertain why, but a popular theory is that hydrocarbons in some form (petroleum, gas, coal) are being exposed to air through cracks formed in dry ground. (Fuel + Oxygen + Heat = Fire Triangle) The last thing California needs are forest fires from below, after so recently fighting off forest fires from lightning above, so firefighters are closely monitoring the area.
