Manaus – Thick smoke from dozens of fires has turned Brazil’s largest Amazon city gray and left residents struggling for clean air. The crisis has lasted more than a month, with flames threatening homes, crops, and health across surrounding municipalities. Local accounts describe an emergency that escalated quickly after the first round of the presidential election.
Daily Life Under a Haze
Otacílio Farias, a 75-year-old farmer who has lived his entire life near the Autaz Mirim River, paused a recent conversation to read a fresh alert on his phone. A fire was burning near a friend’s house. Nearby Lake Miriti, he noted, appeared shrouded at dawn, yet the veil was smoke rather than mist. Farias said the municipalities of Autazes and Careiro da Várzea are enduring the worst fire season he can recall. His throat and nose remain irritated, and community WhatsApp groups fill with urgent requests to protect crops and evacuate elderly neighbors.
Numbers Reveal Rapid Surge
Brazil’s space agency INPE logged 1,921 fire hotspots across Amazonas state between October 1 and 19. That figure represents a 202 percent increase from the same period in 2025, while the daily average rose more than 51 percent compared with late September. Of those detections, 584 occurred inside the Manaus metropolitan region, including 197 in Autazes and 134 in Itacoatiara. The spike followed the first round of Brazil’s presidential vote, a pattern authorities are now examining.
Authorities Move Against Arson
On October 10 the Amazonas state government declared an emergency across 36 municipalities, unlocking federal support. Officials have since focused enforcement efforts on suspected arsonists believed to be setting fires for land clearing or other motives. The declaration came after community members had already spent days battling flames on their own.
Residents Organize Their Own Defense
On October 1, friends of Farias’s 18-year-old son arrived on motorcycles seeking help as fires approached homes. Roughly 100 neighbors joined the effort to protect property and livestock. Similar scenes have repeated across the region, with residents forming ad-hoc teams while waiting for larger government resources to arrive. The smoke continues to drift over Manaus, a key gateway for travelers and researchers heading deeper into the rainforest. Families remain on edge, monitoring wind shifts and phone alerts as enforcement teams pursue those responsible for igniting the blazes.
