Popocatepetl volcano lies just 70 km from Mexico City (pop. 9 million; around 20 million in the metropolitan area) and 40 km from the city of Puebla (1.5 million). It has been in an active phase with ashfall events since 1994.

Currently, ashfall is light and localised around the volcano, where there is a large farming community.

Popocatepetl has been chosen as representative of the Latin American volcanoes within the Pan American Health Organization’s region of influence (our main humanitarian partner).
