Just twelve hours from the first eruption, a second was reported early Sunday morning, Minister of Civil Protection of the State of Mexico, Luis Felipe Puente, announced from his personal Twitter account.
"#Explosion of #Popocatépetl at 06:39 hours, with a height of 2,500 meters in a northwest direction with moderate ash content, the volcanic warning light continues in yellow phase 2," Puente tweeted.
Last week, volcanologists cautioned officials of the impending eruption as haunting flashes of light flickered around the mouth of the volcano which stands just 70 km from Mexico City.
As predicted, the first pyroclastic flows were expelled from the Popocatepetl volcano at 6:58 pm local time Saturday.
Experts are recommending residents abstain from all outdoor activities and wear a mask when outside. Other suggestions included keeping patios, roofs, and water tanks clear of ashes to prevent accidents.
In a statement, the National Center for Disaster Prevention (CENAPRED), “urged not to approach the volcano and especially the crater, the danger of falling ballistic fragments and in case of heavy rain away from Barrancas funds by the danger of landslides and mudflows."
The Popocatepetl volcano is subject to frequent eruptions, the most recent occurring on December 5. So far, no damage has been reported from this most recent disturbance.
