This volcano has been erupting off and on for years now. A few years ago they completely evacuated the resort town at its base, the army occupied it to prevent looting. Eventually it calmed down, and the inhabitants were allowed back in.
Its a picture perfect volcano.
At about the same time the volcano at the edge of Quito was acting up, and they were gearing up for an eruption there, which in the end didn’t happen. Lots of ash, though.
