The Sangay Volcano in Ecuador has demonstrated increased eruptive activity. According to the Geophysical Institute of the National Polytechnic School, surface activity is rated as moderate with an upward trend, while internal activity is also trending upward.

Monitoring has recorded ash columns reaching heights of up to 2.5 kilometers, with wind patterns displacing material toward the northwest. Ashfall has been reported in Chimborazo and nearby localities, including the community of Columbe. Incandescent material has been observed descending the northwest flank up to 200 meters below the crater level. Authorities have advised mountaineers and hikers to avoid the crater area due to the risk of sporadic explosions.
