Popocatepetl volcano news & eruption update

Popocatépetl volcano (Central Mexico) activity update: steaming, weak explosions

Montag Sep 10, 2012 10:05 | VON: T

Steaming Popocatépetl on 9 Sep
Steaming Popocatépetl on 9 Sep
No change has occurred at Popo. CENAPRED recorded 28 weak explosions during 24 hours. When the volcano is not hidden in clouds, a strong steam plume is visible.
Vorherige Nachrichten
SO2 plume from Popocatépetl on 8 Sep 2012 (NOAA)
Sonntag, Sep 09, 2012
The number of weak steam explosions has increased to slightly more than one per hour again, but direct observations were not possible due to cloud cover. NOAA's satellite images show a significant SO2 plume from the volcano as usual. [mehr]
Samstag, Sep 08, 2012
Over the past 24 hours, weak mostly steam explosions occur at an rate of 1 every 2-3 hours. At night, glowing material ejected during such explosions can be sometimes seen. [mehr]
SO2 plume from Popocatépetl on 3 Sep 2012 (NOAA)
Mittwoch, Sep 05, 2012
Activity has remained stable with about 1 weak mostly steam explosion per hour. The crater is weakly glowing at night suggesting that slow growth of the lava dome continues. A significant SO2 plume is being emitted. [mehr]
Sonntag, Sep 02, 2012
Activity has been stable with relatively few and weak explosions of mostly steam (about 1 per hour). CENAPRED decreased the alert level of Popocatépetl to Yellow Phase 2. [mehr]
Popo with glow from the summit seen early on 31 Aug (CENAPRED)
Freitag, Aug 31, 2012
Weak steam explosions occur at frequencies of about 1 per hour. The largest reach 1 km height and contain small amounts of ash, such as at 22:03 on 29 Aug, 00:57 and 02:38 local time on 30 Aug. Glow from the crater is visible at night suggesting that the lava dome is continuing to grow slowly. CENAPRED also registered 3 small volcano-tectonic quakes at 19:51, 19:58 local time on 29 Aug and 10:37 on 30 Aug. [mehr]

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.
