A series of relatively small but powerful eruptions from the snowcapped Popocatepetl volcano prompted Puebla state officials to suspend both public and private school classes at all levels across 22 towns due to falling ash, according to officials.Falling ash, plus gases spewed by the eruptions, can be harmful when inhaled, and in a worse case scenario could trigger the need for massive evacuations.
Images shared on social media in the picturesque colonial-era main plaza of the Puebla state capital showed many people wearing masks to protect themselves from ash in the air. Mexico's disaster prevention center Cenapred maintained its alert level for the volcano at yellow on Thursday, which indicates moderate risk.
