Popocatépetl is a stratovolcano located approximately 70 km (43 miles) southeast of Mexico City, one of the most populous metropolitan areas in the world. The volcano is known for its frequent ash emissions, explosions, and potential for pyroclastic flows. Populations at risk include those living in nearby cities such as Puebla and smaller settlements within 30 km (19 miles) of the crater, which are subject to hazards such as ashfall, lahars, and pyroclastic density currents.
