During the last 24 hours, thanks to the monitoring system of the Popocatépetl volcano, 107 exhalations have been identified, accompanied by volcanic gases and sometimes small amounts of ash. In addition, 1095 minutes of tremor were counted, of which 550 minutes of low amplitude and 545 minutes of medium amplitude, accompanied by an emission of steam, gas and light ash, with heights of up to 1500 m in the west-northwest direction.
During the morning, an episode of tremor occurred accompanied by the expulsion of fragments a short distance from the crater and a column of gas and light ash with a height of about 1300 m in the north-west direction. There is no information on ash falls in nearby towns. Additionally, most of the nighttime glow was observed over the crater.

From the morning and during the day, a constant emission of water vapor is observed, to the north-west.

From 9 p.m. on the 26th, a constant emission of gas and ash is observed and the expulsion of incandescent fragments to a short distance from the crater.

The alert remains at Amarilla Fase 2.
