At Popocatépetl, 138 exhalations were identified during the last 24 hours, accompanied by water vapor, gas and light amounts of ash. In addition, two explosions were detected, the first on 01.11 at 22:03 and the second on November 2 at 8:41, with a plume of more than 2,000 meters. Similarly, 425 minutes of tremor were identified.

With low visibility on the volcano, in the early hours of the morning, it was observed with the emission of water vapor and volcanic gases dispersed in a northwesterly direction.

From 11:06, an episode of tremor accompanied by continuous emission of ashes. It has sometimes been possible to observe an incandescence in the crater. Small thermal anomalies, of the order of 5 MW, are reported by Mirova.

Ash falls have been reported from Amecameca, Juchitepec, Ozumba, Tepetlixpa and Atlautla, State of Mexico, and Ayapango and Cuautla, Morelos.

The VAAC Washington has issued a rating of ash dispersion at a flight altitude of 200 (over 6,000 m.)
