Canyon Fire Triggers Mass Evacuations in Ventura and Los Angeles Counties
Published Time: August 8, 2025, 17:45 (U.S. Pacific Time)
A fast-moving brush fire erupted Thursday afternoon in a mountainous region north of Los Angeles, prompting urgent evacuation orders for thousands of residents as extreme heat and dry weather fueled its rapid spread.
According to Ventura County emergency officials, the blaze—dubbed the Canyon Fire—has already consumed more than 2.3 square miles (6 square kilometers) within hours and remains entirely uncontained. Fire crews are working on the ground and in the air to control the flames, which are moving quickly through rugged terrain.
Fire Ignites Near Lake Piru and Lake Castaic
The Canyon Fire was reported around 1:30 p.m. near Lake Piru, a reservoir located in the Los Padres National Forest. The area lies just south of Lake Castaic, a well-known recreation spot that was scorched earlier this year by the Hughes Fire in January. That blaze destroyed approximately 15 square miles (39 square kilometers) within six hours, forcing evacuation orders and warnings for 50,000 people.
By late Thursday afternoon, officials said the new fire was advancing eastward under dangerous conditions. “This is a very dynamic situation,” Ventura County Fire Department spokesperson Andrew Dowd said. “Hot, dry weather, steep terrain, and heavy vegetation are making this fire extremely challenging to contain.”
Evacuation Orders Affect Thousands
In Los Angeles County, approximately 4,200 residents and 1,400 structures are now under mandatory evacuation orders, while another 12,500 residents remain under evacuation warnings.
The affected areas in Ventura County are less densely populated, though officials confirmed that 56 people were evacuated from the Lake Piru recreation area as a precaution.
LA County Supervisor Kathryn Barger urged residents to comply with evacuation orders immediately.

“Extreme heat and low humidity in our north county have created dangerous conditions where flames can spread with alarming speed,” Barger said in a statement. “If first responders tell you to leave, go—without hesitation.”
Firefighting Efforts Underway
As of Thursday evening, more than 250 firefighters were engaged in battling the blaze, supported by helicopters and fixed-wing aircraft dropping water and fire retardant.
Dowd noted that while ground crews are making progress in some areas, the combination of steep slopes, high winds, and dry fuel is complicating containment.
Canyon Fire Adds to Statewide Wildfire Crisis
The Canyon Fire is emerging just as California is already battling its largest wildfire of the year—the Gifford Fire—burning hundreds of miles away in the Los Padres National Forest in Central California.
The Gifford Fire has scorched 154 square miles (399 square kilometers) and is only 15% contained, according to the California Department of Forestry and Fire Protection (Cal Fire). It began as at least four smaller fires that erupted last Friday along State Route 166 near Santa Maria, leading to highway closures in both directions. At least four people have been injured, and the cause of the fires remains under investigation.
Heat Wave Intensifies Wildfire Threat
Fire officials warn that wildfire danger will remain high through the weekend across much of inland California due to an intensifying heat wave. August and September are historically the most active months for wildfires in the state.
“In Southern California, the threat is driven by persistent drought, high grass loads, and weakening coastal moisture,” Cal Fire said in its latest wildfire forecast.
Residents in high-risk areas are urged to prepare emergency evacuation kits, monitor official alerts, and take precautions to reduce fire hazards around their properties.
