Cenapred has identified in the past 24 hours at Popocatépetl a hundred exhalations, accompanied by gas, small amounts of ash and incandescent fragments; a moderate explosion, around 2:59 am, produced an eruptive column 1,000 meters high dispersing to the south and the expulsion of incandescent fragments some 800 meters on the flanks.

Seismicity is further characterized by 129 minutes of low amplitude tremor.

During the day of the 22nd, a constant emission of gas and occasionally also a little ash is reported.

On March 23, around 12:41 am, a new explosion was accompanied by a plume of ash of medium height and ejection of incandescent materials up to 700 meters on the high flanks.

Seismicity is characterized by increasing volcano-tectonic earthquakes, the number of which reaches 25 / day.

Sulfur dioxide emissions are around 1,300 tonnes / day.

The last bulletin of March 23 reported bombs and pyroclastic flows likely to affect an area up to 2 km from the crater.
