A massive column of dense, dark grey to black smoke billows upwards and across the sky over San Francisco Ocotlán (Ocotlán), Mexico. The upper left sky is light blue, transitioning to a muted yellow-orange near the horizon, which is partially obscured by the smoke. In the foreground, a row of multi-story, flat-roofed buildings with predominantly white facades and some orange architectural accents is visible. Solar panels are installed on several rooftops. A metal ladder rests against an elevated structure on one of the central rooftops. A tall, lattice telecommunication tower stands to the left, and another, partially visible tower is on the far right. A large, dark, conical or dome-shaped elevation is discernible in the distant background, partially veiled by the smoke. No persons are depicted. The scene indicates a significant emission of dark smoke.
