At Fuego, weak, moderate and strong explosions were observed, expelling columns of ash at a height of 4500 and 4800 meters above sea level, extending west and southwest over a distance of about 20 kilometers. The explosions generate moderate and strong avalanches of incandescent blocks, some of which cause fires in the vegetation zone. Sounds similar to train locomotives are sustained for periods of 2-5 minutes.

Ash falls in the villages of Panimache, Santa Sofía, Morelia, Morelia. , Yucales and surroundings. The loud explosions generate moderate to loud rumblings that rattle homes and windows for a distance of 7 km around the volcano.
