Popocatépetl - ash emissions on 08/23/2020 at 8:01 am and 8:27 am - Doc. webcamsdeMexico

Over the past 24 hours, the Popocatépetl volcano monitoring system has identified 153 exhalations accompanied by volcanic gases and sometimes small amounts of ash, reaching up to 1,100 meters above the crater, drifting southwest

In addition, 840 minutes of low amplitude tremor associated with the constant emission of water vapor, gas and low ash content were recorded.

During the night, an incandescence was observed inside the crater, and the constant emission of water vapor and gas in a south-easterly direction, which continues in the morning of August 23.

The alert level remains at amarillo Fase 2
