If you don't live on the West Coast of the United States, you might not have heard about the massive gas well leak that's been venting natural gas into the atmosphere at a rate of more than 100,000 pounds per hour for more than two months.
Infrared video that the Environmental Defense Fund captured in December shows that the natural gas is billowing like a volcano just above Burbank, California, on a hilltop in the Aliso Canyon area.
