Popocatepetl is one of Mexico's most active volcanoes. After almost 50 years of dormancy, "Popo" came back to life in 1994 and has since then been producing powerful explosions at irregular intervals.
In the past centuries befor European invasions, large eruptions produced giant mud flows that have buried Atzteque settlements, even entire pyramids.

Popocatépetl volcano (Central Mexico) activity update: 1-2 weak explosions per hour with glowing ejecta, strong SO2 emission
Wednesday Aug 29, 2012 14:05 PM | BY: T
Bluish gas emission from Popo on 29 Aug
Steam explosion with some ash early on 28 Aug
A slight increase in activity can be noted since yesterday. There is about 1 weak steam explosion per hour, with an increase in frequency last evening. Some of the explosions produce small amounts of ash and plumes up to 1.5 km high, such as one at 03:56 early yesterday. Glowing material can be seen ejected during such events at night.
A significant SO2 plume is visible as a bluish haze during clear weather and on satellite images.
Not much has changed at the volcano. A slight increase in the frequency of small explosions to about 1 or 2 per hour can be noted. Some of the explosions produce not only steam, but some ash, and the more powerful ones eject glowing material falling back into the crater. ...
Activity remains relatively low. About 1 weak steam explosion has been occurring per hour over the past day. Still, the volcano produces a large SO2 plume visible on yesterday's satellite image.
Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
