Aldea del Fresno Wildfire Stabilized at 330 Hectares After Evacuations in Madrid

Ignition and emergency orders

The wildfire started at 14:30 on Wednesday, 19 August 2026, at kilometer 52 of the M-510 road near the municipality of Aldea del Fresno. Strong wind gusts accelerated the spread of the flames through the southwestern sierra of Madrid, creating difficult operating conditions for local emergency services. Regional authorities initially ordered the confinement of Aldea del Fresno, a town of 3,500 residents, alongside the neighboring municipality of Villamantilla, which has 1,660 residents. As flames approached residential sectors, emergency teams evacuated the Palomeque, Manga de la Pedrera, and Carbajo urbanizations, as well as multiple houses in the María Elena development. Movement between the towns was restricted, preventing residents in Villamantilla from traveling toward Aldea del Fresno during the initial response.

Emergency mobilization and infrastructure cuts

The rapid advance of the fire prompted the regional government of Madrid to activate Operational Situation 2 under the Infoma civil protection emergency plan. This level applies when fires threaten population centers or non-forest property, enabling the coordination of national state assets and extraordinary intervention teams. The Ministry of Defense dispatched personnel from the Military Emergency Unit (UME), based in Torrejón de Ardoz, to assist regional brigades in containment efforts. Ground operations involved 20 terrestrial firefighting crews and forest agents working alongside five aerial aircraft. Road authorities closed the M-510 between kilometers 50 and 54, while the M-507 was shut between kilometers 9.5 and 17, forcing the Madrid Regional Transport Consortium to suspend bus line 548.

Very attentive to the evolution of the fire in Aldea del Fresno that has prompted the activation of Operational Situation 2 of the INFOMA plan. Please exercise extreme caution in the area and always follow the instructions of the security and emergency services.

Containment and status downgrade

Emergency operations progressed through the late afternoon as dropping temperatures and weakening winds aided firefighting crews on the ground. Following an assessment at the Integrated Operational Coordination Center (Cecopi), regional authorities stabilized the fire and downgraded the response to Operational Situation 1. The provisional assessment established that the wildfire affected 330 hectares of land. Confinement measures for surrounding towns were subsequently lifted, allowing residents to resume movement under localized safety advisories. Firefighters and forest brigades managed to halt the active spread before the blaze could reach additional residential infrastructure.

Overnight consolidation and origin inquiry

After stabilizing the main perimeter, emergency services adjusted their deployment to maintain control over the burn zone during the night. A team of 17 firefighter crews remained stationed in the affected territory to reinforce boundary lines and douse interior hotspots. The Government Delegate in Madrid, Francisco Martín, thanked the Civil Guard and deployed personnel across all administrative levels for their joint extinction work. Martín confirmed that the formal investigation into the physical cause of the fire at the M-510 roadside remains open. Regional emergency officials advised the local population to continue following official alerts while cooling operations proceed.
