Overview
- Peru’s geophysical institute confirmed a volcanic mudflow descending the southwest flank of Misti through the Huarangal–Los Incas ravine toward the Chili River on the night of January 31.
- Cellphone alerts urged residents to stay away from the ravine and to avoid crossing bridges and fords in the area.
- COEN–INDECI cautioned that the flow could affect homes, crops, and transport routes near its path and advised residents to identify safe zones, evacuation routes, and prepare emergency kits.
- IGP stated it maintains continuous tracking of the event to report on the flow’s evolution and downstream risk.
- Technical reports describe the lahar as a cold mixture of water, ash, and rock mobilized by rains, noting it is not linked to an eruption.
