Mexico’s largest active volcano, Popocatépetl, erupted Monday afternoon, sending a plume of ash nearly nearly two-and-a-half miles into the air and sending glowing hot rock fragments into neighboring pastures as far as a mile away, starting several small wildfires, according to a report in the Spanish website informador.com.mx.
The 17,930-foot volcano is the second-tallest peak in Mexico, and has seen a number of large eruptions since 1994. In 2000, the volcano produced one of the most powerful eruptions in recent history, which prompted numerous evacuations.
After Monday’s eruption, the volcano alert level was raised to a Yellow Phase 2 (Phase 4 is cataclysmic), with 650,000 people living inside the zone of high risk.
While the situation seems stable at the moment, the Mexican government organization Protección Civil is helping nearby neighborhoods take precautions, according to informador.com.
