Confined Aldea del Fresno and Villamantilla
The evolution of the fire has led authorities to order the confinement of the populations of Aldea del Fresno and Villamantilla. The measure implies that neighbors must remain inside their homes, close doors and windows, and avoid movements until new instructions are received.
For the moment, authorities have not communicated evacuations nor have they offered a first estimate of the affected area. There has also been no official information regarding possible personal injuries, affected homes, or the causes of the fire.
The activation of Operational Situation 2 allows for the coordination of regional resources to be reinforced and to request the incorporation of extraordinary means if the emergency requires it.
New fire in the Sierra Oeste of Madrid
The fire in Aldea del Fresno is a new blow for Sierra Oeste, which was already hit this summer by a giant fire between late July and early August.
The Community of Madrid declared those fires controlled on August 4 and then reduced the operation to Operational Situation 0 of the INFOMA. The official balance placed the affected area at approximately 27,000 hectares within the Madrid territory and indicated that the fire affected 17 municipalities in the Sierra Oeste.
Aldea del Fresno already directly suffered that emergency. Its approximately 3,500 inhabitants had to be evacuated due to the advance of the flames from the fire declared in Villa del Prado.
Three weeks later, the declaration of this new fire again forces the adoption of protective measures for the neighbors of the region.
What the Operational Situation 2 of the INFOMA means
The Operational Situation 2 is activated when a forest fire can seriously affect people, property, or infrastructure and requires mobilizing additional resources beyond those initially planned. The management of the emergency remains in the hands of the Community of Madrid, although this level allows for the request of resources from other administrations, including state support, if the evolution of the fire makes it necessary.
