Diaporama | |   Satellite images of Popocatepetl volcano (c)Google Earth View 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.

Bright glow is visible above the crater at night. No explosions occurred during the past 24 hours.
Actualités précédentesdimanche, mars 02, 2014 Current activity at the volcano is low with only occasional small puffs of ash. CENAPRED published an aerial picture showing the new (so far very small) lava dome in the crater. ... [details]jeudi, févr. 27, 2014 The volcano's activity increased yesterday. CENAPRED counted no less than 544 small to moderate emissions during the 24 hours between 25-26 Feb. ... [details]
lundi, févr. 24, 2014 Activity at the volcano has remained unchanged and is currently low. The number of explosive emissions of generally weak size is typically less than 10 per day. SO2 emissions remain elevated and glow at night is visible as a further indicator that magma continues to rise slowly to the crater. [details] lundi, févr. 17, 2014
No significant changes in the currently low activity of the volcano have occurred recently. The volcano produces a small number (less than 10 usually) weak explosive emissions of steam, gas and sometimes ash on a daily basis, and magma continues to rise slowly to the summit where a lava dome forms. This is evidenced by glow at night, and was confirmed during a recent overfly with the support of the Mexican Navy. ... [details]dimanche, févr. 02, 2014 Activity at the volcano has remained unchanged and weak. Only few (less than 10 per day) and generally weak emissions of steam, gas and minor amounts of ash have been recorded. Weak glow is visible at the crater at night. [details]Background: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.
