Popocatépetl volcano

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: steaming and strong SO2 emission, occasional weak steam and ash explosions

Friday Sep 28, 2012 11:32 AM | BY: T

5 weak explosions and tremor pulses were registered between 26-27 Sep by CENAPRED. Satellite data show a strong SO2 plume.

Tuesday, Sep 25, 2012

The frequency of explosions has drastically dropped to only about one every 3-4 hours, but lava glow above the crater and strong SO2 emissions indicate that lava continues slowly to rise at the volcano and build up the lava dome in the crater. [more]

Popocatépetl volcano (Central Mexico) activity update: strong steam and gas emission, small explosions

Saturday, Sep 22, 2012

Activity has not changed much during the past days. there are about 1-2 weak mostly steam explosions per hour, the larger of which produce small ash plumes. The volcano is emitting a strong steam and SO2 plume often visible on satellite. Night-time glow above the crater can be observed. [more]

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.
