Sabancaya is a stratovolcano located in southern Peru. It is known for frequent moderate explosive eruptions producing ash plumes, pyroclastic flows, and minor lava flows. Volcanic hazards include ashfall that may affect nearby communities such as Arequipa, which is approximately 70 km (43 miles) to the southwest. Populations in the Colca Valley are also at risk from volcanic activity.
