Los Angeles wildfires of 2025

Los Angeles wildfires of 2025, series of wildfires that scorched parts of the Los Angeles region in January to early February 2025. The episode was marked by the emergence of two major conflagrations—the Pacific Palisades Fire (also known as the Palisades Fire) and the Eaton Fire—and several other smaller wildfires, most of which began between January 7 and January 9. The severity of the wildfires was exacerbated by weather and climate factors, including the arrival of Santa Ana winds, which peaked during the wildfire outbreak, fueling the fires’ explosive growth and driving the fires through heavily wooded areas and into residential neighborhoods. The disaster claimed 30 lives and forced more than 180,000 people to flee their homes. Although early estimates of the total economic cost of the disaster topped $250 billion, later estimates reduced the figure to between $76 billion and $131 billion. Still, the Los Angeles wildfires ranked among the top 10 costliest disasters to strike the United States (see also tropical cyclone: Costliest hurricanes in the United States).

Causes and contributing factors

The outbreak of wildfires in the area was attributed to a number of causes. The careless use of New Year’s Eve fireworks is suspected of starting what would become the largest fire, the Palisades Fire, on New Year’s Day (see also New Year festival). This precursor event is thought to have burned fewer than 10 acres (4 hectares) before officials believed that it was extinguished, only to have its remnants flare up on the morning of January 7. The Palisades Fire became a conflagration that burned 23,448 acres (9,489 hectares) of forested slopes between the cities of Santa Monica and Malibu. Other fires, including the Eaton and Hurst fires—which scorched 14,021 acres (5,674 hectares) and 799 acres (323 hectares), respectively—may have been ignited by sparks from downed or idle power lines or other improperly maintained electrical utility equipment, which prompted some residents of affected communities to file lawsuits alleging negligence by the public electrical utility Southern California Edison. However, the causes of other fires remained unclear; the Kenneth Fire, for example, is suspected of being set intentionally (see arson) and the Auto and Lidia fires are subjects of ongoing investigations.

The rapid spread of the fires was heavily influenced by several factors acting concurrently. The effects of decades of excessive fire suppression built up the fuel load in forests and neighborhoods. The ongoing effects of climate change produced extreme rain events in 2023 and 2024 that drove the brisk growth of vegetation in the run-up to the fires. Climate change also hastened the onset of drier-than-normal conditions in late 2024, increasing by 35 percent the likelihood of the start of wildfires in the region, according to the World Weather Attribution organization. Climate-driven drought was also exacerbated by the arrival of the Santa Ana winds in late August or early September—and together both of these forces dried out vegetation throughout the fall. The Santa Ana winds reached peak frequency and intensity in December 2024 and January 2025, which coincided with the flaring of the wildfires.

Damage and destruction

Collectively, the wildfires burned more than 50,000 acres (20,200 hectares, or 78 square miles [202 square km]), according to several sources, and destroyed more than 16,000 homes, businesses, and other buildings, in addition to thousands of automobiles. The largest fires, the Palisades and Eaton fires, produced the costliest damage, in part because they cut across suburban landscapes. The Palisades Fire reduced much of the suburb of Pacific Palisades to ash, destroying 6,837 structures and claiming 12 lives. The Eaton Fire burned large parts of the unincorporated community of Altadena, including 9,414 structures, and caused the deaths of 18 people. In both areas, numerous injuries were reported among both residents and first responders.

Firefighting

Efforts to extinguish the blazes were hampered by the winds, which surpassed 100 mph (160 km/hr) in some locations, pushed fire lines down slopes into new patches of dried, combustible vegetation, and sent embers from burned materials into the air. Those embers later fell several miles away, starting new fires. To manage the chaotic, constantly changing situation, traditional firefighting methods were paired with innovative technologies. Firefighters on the ground approached fires from the flanks, while also drenching critical structures with water to prevent ignition and deploying bulldozers and other heavy equipment to create firebreaks. In addition, fixed-wing aircraft, such as modified C-130 transport planes, and rotary aircraft, such as the Sikorsky S-70 Firehawk and the Boeing CH-47 Chinook, dropped water and fire retardant, as drones equipped with infrared sensors and cameras directed by artificial intelligence provided real-time data of the location, pace, and movement of fires (see also unmanned aerial vehicles). On the ground, the StormCell—a vehicle that uses jet engines to create wind gusts up to 300 mph (482 km/hr)—was introduced to counter prevailing winds and beat back flames.

The backbone of the firefighting effort was provided by numerous local, state, and federal firefighters and other emergency personnel. More than 8,500 staff from California were assigned to the firefighting effort, which included several hundred firefighters drawn from local and regional municipalities. Roughly 800 incarcerated firefighters were also enlisted. On January 8, U.S. Pres. Joe Biden signed a federal emergency declaration for the state, which committed the federal government to send additional staff and resources—including tanker aircraft, firefighting helicopters, and U.S. Forest Service fire engines—to Los Angeles.

Firefighting efforts were also buoyed by assistance from the international community. Canada sent 60 firefighters and provided specialized equipment, including two tanker aircraft from Quebec, firefighting helicopters, and incident management teams from several provinces. Mexico sent a team of 72 personnel made up of firefighters, physicians, engineers, and search-and-rescue experts from the National Forestry Commission and the Ministry of Defense. Israel provided logistical support to help create fire zone maps and situational assessments for U.S. teams. Japan pledged $2 million to the American Red Cross to assist with food and counseling for victims relocated to shelters and other evacuation sites. Other countries, including Ukraine and Iran, also offered to send firefighters, the latter also offering to send financial assistance through the Iranian Red Crescent Society (see also Red Cross and Red Crescent).

Management response

The wildfires revealed significant challenges in firefighting and evacuation management across multiple levels of government. Prior to the fires, a public dispute between Los Angeles Fire Department (LAFD) Chief Kristin Crowley and Los Angeles Mayor Karen Bass had ensued over the LAFD’s budget. Crowley had warned that budget cuts, including reductions in overtime pay, would affect the department’s training and emergency readiness. Bass, however, had disputed Crowley’s claims, asserting that the cuts had not affected the LAFD’s readiness. As the fires escalated, communication breakdowns arose; for example, several evacuation text messages were sent to the wrong locations, confusing residents. Water pressure in the city’s pipes dropped several times because of water demand, leaving firefighters in some locations with inadequate resources to fight the fires at times. Relations between Crowley and Bass sank on February 21, when Bass dismissed Crowley from her post, blaming the chief for inadequate preparation and response to the wildfires.

Changes to federal policy stemming from the transition between the presidencies of Biden and Donald Trump threatened relief efforts. Despite Biden’s January 8 declaration, which released federal disaster aid through the Federal Emergency Management Agency (FEMA), two days after his January 20 inauguration, Trump threatened to suspend disaster aid until California Gov. Gavin Newsom and the state’s legislature adopted voter identification laws and turned over parts of the state’s water management policy by handing the power over to FEMA, which would allow the federal government to ignore California’s strict environmental regulations.

Trump also attempted to insert himself into the firefighting efforts directly; he claimed that releasing water from reservoirs in California’s Central Valley would flow to southern California and assist in firefighting efforts. Ignoring advice from state and local officials (who noted that there was no direct hydrological connection between the Central Valley and southern California and that southern California reservoirs were already providing adequate water to Los Angeles’s water system), Trump ordered the U.S. Army Corps of Engineers to release roughly 2.2 billion gallons (8.3 billion liters) of water. Water managers and farmers pointed out that the water release came too early in the season to help with agriculture; they also worried that the loss of this stored water would force them to make additional withdrawals from stressed underground aquifers to make up the difference later in the season.

Relief and recovery

Still, relief and recovery efforts mobilized substantial financial resources from public and private sources. By March 2025, federal payouts to disaster victims had surpassed $2 billion and insurance companies had provided more than $12 billion. The city’s music community also raised money for fire victims. Music industry moguls Shelli and Irving Azoff (in partnership with the entertainment enterprises of Live Nation and AEG Presents) sponsored a benefit concert on January 30. The concert, which featured a collection of well-known artists in American music, including Lady Gaga, Billie Eilish, and the Red Hot Chili Peppers, raised more than $100 million. In addition, more than $9 million was raised during the Grammy Awards, which aired on February 2, and the nonprofit organizations the Recording Academy and MusiCares reported that they had raised a combined $24 million during the same period.
