Mexico's El Popo Volcano Explodes in Darkness

Popocatépetl, Mexico's most active volcano, has been spewing hot ash and gas into the atmosphere this week, prompting temporary closures of the airport at Puebla because of ashfall and a seven-mile exclusion zone around the mountain.

This footage shows the mountain's blast early Wednesday morning, March 30, before sunrise.
