.................... LOS ANGELES (KTLA) - Many more structures are believed to be destroyed as fire crews struggle to gain containment on the 17,000-acre Palisades Fire: the most destructive wildfire in Los Angeles history. Preliminary reports indicated the number of damaged or destroyed structures is "in the thousands," Los Angeles City Fire Chief Kristin M. Crowley said during a news conference Thursday morning. "It is safe to say that the Palisades Fire is one of the most destructive natural disasters in the history of Los Angeles." The Palisades Fire, which erupted on Tuesday afternoon, quickly swept through residential and commercial districts in this affluent coastal community, prompting tens of thousands of people to flee. Many of the structures lost are businesses and homes. A decimated neighborhood in the Pacific Palisades. Jan. 9, 2025. (KTLA)Sky5 view of the Palisades Fire on Thursday, Jan. 9, 2025.

(CalFire) Thursday morning, the fire was mapped at 17,234 acres with no containment. The cause remained under investigation. More than 800 firefighting personnel, with the help of fixed-wing aircraft and helicopters, are battling the blaze. However, the same winds that fueled the fire have limited the use of aerial resources. “Extreme fire behavior, including short and long-range spotting, continues to challenge firefighting efforts for the Palisades Fire,” CalFire said in a bulletin. “Winds gusts up to 60 MPH are expected to continue through Thursday, potentially aiding in further fire activity and suppression efforts.” The evacuation order extended throughout the Pacific Palisades to the Pacific Ocean and included areas of Santa Monica, Malibu and Topanga. Residents and businesses in Calabasas remained under an evacuation warning on Thursday. The Palisades Fire perimeter and evacuation zones on Thursday, Jan. 9, 2025. (CalFire) With 1,000 structures destroyed, the Palisades Fire is already far more destructive than the second-most destructive wildfire in Los Angeles history, according to statistics from the Wildfire Alliance, the Associated Press reported. Damage is believed to be in the tens of billions of dollars. The last most destructive fire was the Sayre Fire in November 2008, which destroyed 604 structures in Sylmar. The Palisades Fire was one of several large wildfires that have forced evacuations in the Los Angeles area this week. The Eaton Fire has claimed five lives and destroyed a still-undetermined number of homes in the areas of Altadena and Pasadena. Also, thousands of residents fled their homes Wednesday evening when a fast-moving brush fire erupted in the Hollywood Hills. The Sunset Fire charred around 40 acres before crews gained the upper hand and lifted most evacuation orders around midnight.
