The blaze erupted Tuesday afternoon and rapidly swept through an area where Kern County fire authorities say there is no history of any fires on record, meaning vegetation hadn’t burned there in more than a century.

To the north, a fire that destroyed eight residences and a few outbuildings as it spread across about 25 square miles of the Sequoia National Forest in the Sierra Nevada was 20 percent contained, authorities said.

The cause of the fires is under investigation.
