Overview
- The eruption began Monday morning and intensified through the night with lava fountains, frequent explosions and ash columns reaching 5,000–7,000+ meters, according to INSIVUMEH.
- INSIVUMEH reported multiple pyroclastic flows that ran 5–7 kilometers down ravines such as Barranca Seca and Ceniza, which officials say pose the immediate danger to flank communities.
- CONRED declared an orange-level national alert and ordered preventive evacuations and sheltering for villages including El Porvenir and Las Lajitas while authorities closed Route National 14 and suspended in-person classes.
- Ash plumes have drifted tens to more than 100 kilometers to the west and northwest, prompting aviation advisories and warnings to protect water, food and respiratory health in affected towns.
- Reported counts of evacuees and people affected vary across sources, no confirmed deaths have been announced, and officials continue round-the-clock monitoring because activity could change over the next 24–72 hours.
