At least 150 firefighters worked to extinguish the fire in a remote area of Malibu and were expected to remain on site most of the day to guard against lingering hot spots.
The wildfire started as one-fourth acre in heavy brush located off Tuna Canyon Road near Pacific Coast Highway just before 1 a.m., according to Los Angeles County Fire Department officials.
The fire was 50% and was surrounded by a line of cleared vegetation just before 10:30 a.m., but it was no longer spreading and the flames were out, officials reported.

No structures were threatened and no injuries were reported, fire officials said.
Footage from the scene showed a thick plume of smoke billowing into the sky. AIR7 HD was over the scene around 5:30 a.m. as some flames showed through white smoke.
Fire officials said the fire was initially difficult for crews to reach on the ground. Three water-dropping helicopters helped fight the fire from above, officials said.
The #TunaFire is burning in a remote area and has presented access challenges. From the road, firefighters have had to hike in approximately 2,000 feet + worth of hose to get to the area currently burning. This has been done via a narrow trail and in steep, rugged terrain. pic.twitter.com/tLfI9gChiR— L.A. County Fire Department (@LACoFDPIO) July 9, 2021
The California Highway Patrol issued a SigAlert, shutting down Tuna Canyon Road from Las Flores Heights Road to PCH.
Details on how the fire started were not immediately clear. However, there is increased fire danger across the Southland as another heat wave grips the region.
