The Popocatepetl volcano, just outside Mexico City, has erupted occasionally since 1994, but in the past week it has rumbled daily.
Scientists recorded hundreds of explosions and webcams aimed at the volcano showed it spewing out glowing material. From Mexico City, you can see a column of ash rising from the top.

Smoke, ash and molten rock poured into the sky from Popocatépetl on Sunday, posing risks to aviation and communities below. Two airports in Mexico City temporarily halted operations on Saturday due to ash fall.

Like Mount Vesuvius in Italy and Mount St. Helens in Washington State, Popocatépetl is a stratovolcano capable of catastrophic and explosive eruptions, the last of which occurred around the year 800.

Mexican scientists say it’s impossible to say how long this new activity will last, or whether recent activity could lead to such an explosion. But they say the 17,900ft volcano, known locally as El Popo, will give enough warning to evacuate the millions who could be in danger.
Mexico has deployed about 7,000 troops to the area to help prepare for an evacuation if needed. More than 25 million people live within 60 miles of the peak.
