During the last 24 hours, thanks to the monitoring systems of the Popocatépetl volcano, 225 exhalations have been identified, accompanied by emissions of water vapor, volcanic gases and small amounts of ash. In addition, 109 minutes of low amplitude tremor were recorded.
During the night, and in the morning, a light emission of water vapor and gas was observed, at the time of this report there is a partial visibility of the volcano, any emission will have a northeast direction.
CENAPRED urges not to approach the volcano and especially the crater, because of the danger posed by the fall of ballistic fragments and, in the event of heavy rains, to stay away from the bottom of the ravines because of the danger of flows mud and garbage.
