Activity remains low. About 1 weak eruption per hour has been observed during the past day by CENAPRED. SO2 emissions remain high (which is typical for Popo during phases of activity). ... alles lesen
Sonntag, Aug 12, 2012
Only 3 weak explosions were observed during 9 hours of recent observation. The volcano is emitting a significant steam and gas plume with lots of SO2. ... alles lesen

During the past day, activity has remained low. Popo produced about 1 weak explosion per hour emitting mostly steam. A significant SO2 plume was visible on NOOA's satellite image of yesterday. Seismic recordings are currently suffering malfunctioning, but don't suggest much activity. ... alles lesen

CENAPRED reportss a total of 15 small-intensity "exhalations" of steam and gas, and sometimes with minor amounts of ash. Tremor at high frequency occasionally occurs in the seismic signal. ... alles lesen

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.
