"A flame burning for almost a day at the Aliso Canyon natural gas facility [in Los Angeles] north was extinguished [but] it’s unclear what was fueling the fire"

LA Daily News:

The “small, low flame” was spotted Monday, days after the Saddleridge fire burned through the area. The wildfire, which was sparked Thursday night in Sylmar, was 45% contained by Tuesday morning and has burned 8,391 acres.

“There’s nothing logical there that’s burning,” . . . “It’s just fire that’s coming out of the dirt.”

...

The facility was the site of the 2015 gas leak, the largest such one in U.S. history, that kept Porter Ranch residents out of their homes for months.

SoCal Gas told residents in the Porter Ranch area last night that a fire is burning in their Aliso Canyon gas storage field. They don’t know what’s burning and apparently don’t know how to put it out. This is site of the 2015 blowout, largest natural gas leak in US history.@ABC7 pic.twitter.com/fLtjiMTVom
