Over the past 24 hours, Cenapred has identified 696 low-to-medium intensity exhalations with the emission of gas and water vapor in the Popocatépetl.
Twenty-two explosions marked the volcano, accompanied by plumes moderately loaded with ashes, then dispersing to the north and northwest
The level of volcanic alert remains in Amarillo phase 2.

The Reventador always has a high and continuous internal activity.
At the end of June, a lava flow took place on the east-northeast flank.
In recent days, we can see on the thermal images of the webcam, the existence of two flows, on the south-south-west and south-east slopes, of several hundreds of meters long.
The IGEPN refers to nocturnal explosions, incandescence at the crater and falling of incandescent blocks on the flanks up to 800 meters below the crater.
