That blaze – called the Topanga Canyon Fire – scorched about four acres and forced the closure of Topanga Canyon Boulevard about one-half mile from PCH, which remained open, authorities said.
One firefighter sustained minor, heat-related injuries in the Calabasas fire as of 4 p.m. Thursday, according to Los Angeles County Fire Inspector Gustavo Medina.
About 195 firefighter personnel were on scene, Medina said.
Officials said no structures are threatened, as of 3:40 p.m.
Firefighters are battling a brush fire in heavy, dry vegetation on a Malibu hillside Thursday afternoon.
“[Both fires are] burning away from Malibu, so we’re monitoring them, we know that winds can be sneaky, so we always keep an eye on things even when at the moment it looks like it’s ok for Malibu, we’re keeping an eye on it”, Dueñas said.
The second-alarm fire, which became a third-alarm fire for a time, was reported at 3:09 p.m. and had burned about 20 acres as of 4:45 p.m.
Pacific Coast Highway had also been shut down in both directions in the Topanga Canyon area, but was reopened by around 6:30 p.m.
Topanga Canyon Boulevard was closed, he said. The fire started in the area of Topanga Canyon north of PCH. No structures were reported threatened in that fire.
