Mexico: Disruptions ongoing due to increased activity at Popocatepetl Volcano as of May 22 /update 1

Event

Authorities raised the alert level at Popocatepetl Volcano following further volcanic activity, approximately 72 km (45 miles) southeast of Mexico City, as of May 22. The active volcano has shown heightened levels of activity in recent days, and the current eruptive episode has led to ashfall being reported in several municipalities in Morelos, Puebla, and the State of Mexico states. Officials from the National Center for Prevention of Disasters (CENAPRED) have reported 31 exhalations, six explosions, and 1,136 tremors at the volcano May 20-21. CENAPRED increased the volcanic alert level from Yellow Phase 2 to Yellow Phase 3 May 21. The public is warned not to approach the volcano, especially the crater, because of the danger involved in the fall of ballistic fragments. An exclusion zone of 12 km (7 miles) is in place around the crater. During periods of heavy rainfall people are advised to avoid ravines due to the danger of mud and debris flows.

Benito Juarez Mexico City International Airport (MEX), Felipe Angeles International Airport (NLU), and Puela Hermanos Serdan Airport (PCB) all suspended operations for several hours on May 20 due to increased volcanic activity and ash fall in the area; operations at all three airports had resumed as of early May 22. Face-to-face classes in schools have been suspended in dozens of municipalities across Puebla and people are being advised to limit outdoor activities due to the threat posed by ashfall.

Volcanic events could result in further light to moderate ashfall in nearby towns and possible pyroclastic flows and mudflows. The volcano could produce additional ash and gas emissions, tremors, and explosions in the coming weeks. Any large-scale eruption at Popocatepetl could prompt transport disruptions in the surrounding area. Ashfall may reduce visibility and cause hazardous driving conditions. Continued flight disruptions are possible, including at Benito Juarez International Airport (MEX) and Felipe Angeles International Airport (NLU) in Mexico City, and Puebla Hermanos Serdan International Airport (PBC), if a significant eruption occurs and winds push ash clouds in the general direction of the airports. Officials may also restrict road travel between Xalitzintla and San Pedro Nexapa north of the volcano.

Advice

Plan for possible transportation disruptions if operating near Popocatepetl. Avoid areas near the volcano. In the event of a large eruption, use face masks and observe other precautions to avoid ash inhalation. Confirm flights via MEX, NLU, and PBC if volcanic activity intensifies.
