Mexico's long-menacing Popocatépetl volcano has erupted again, continuing a pattern of activity that began in mid-April, and causing worry for the more than 30 million people that live within range of the Puebla-based mountain.

According to Volcano Discovery, the eruption began around 7:28 PM on Tuesday, with emissions of steam and ash and even a fiery explosion of burning fragments of rock, which were shot as far as 700 meters from the volcano.
