41,000 people evacuated the Popocatepetl volcano leashes a potentially deadly eruption
The Popocatepetl volcano has spewed out a mile-high plume of ash into the sky - putting scores of lives at risk.
The Mexican city - just 35 miles from Mexico City and 20 miles from nearby Peubla - is now on evacuation alert.
It last saw a major eruption in 2000, yet 41,000 people were evacuated in advance - averting catastrophe.
Activity has been increasing since 2012 following a minor eruption in 2005.
Now officials are so worried about a potential disaster they have issued an early warning.
The volcano has erupted 20 times in nearly 500 years.
Another volcano, the Colima, sent out a 1.8-mile high eruption earlier this month.
A report on wired.com said:
"Two Mexican volcanoes have been increasingly active.
"Popocatepetl produced a number of explosions as lava reaches the surface at the active vent, as evidenced by incandescence spotted at the volcano's summit.
"Most of the explosions produced ash-rich plumes that reached hundreds of meters over the volcano, "Some officials are saying that there is a heightened danger of a large explosive eruption from Colima because it has been over 100 years since that last large eruption.
"The heightened explosive activity at Colima has prompted preparations for evacuations if the restlessness continues or increases."
