Sangay is a stratovolcano located in central Ecuador and is one of the country’s most active volcanoes, characterized by frequent ash emissions, lava flows, and pyroclastic activity. The volcano poses hazards including ashfall that can affect surrounding rural settlements and agricultural land to the east and southeast. Larger eruptions can produce lava flows, pyroclastic flows, and lahars, with the closest population centers over 30 km (19 miles) away.
