Popocatepetl volcano (Mexiko) activity update: low-intensity exhalations, incandescence at the volcano

Tuesday Feb 21, 2012 11:05 AM | BY: T

In the last 24 hours the monitoring system of Popocatepetl volcano registered 21 exhalations accompanied by low-level emissions of steam and gas. The most important took place yesterday at 11:46 h, 16:21 h, 19:34 h, 20:24 h today at 02:53 h were accompanied by ash.
Also there was a spasmodic tremor lasting 2 min. During the night glow was observed on the volcano. Other monitoring parameters remain without important changes. (Source: CENAPRED)

Popocatépetl volcano's activity is increasing. On 25 Jan at 10:10 local time, an ash explosion produced a plume of 3 km height drifting NE. During the past days, strong degassing and steaming has been observed as well as periods of low-frequency tremor. At night (see webcam image), a constant glow can be seen from the summit crater, suggesting that the lava dome might have started a new phase of growth. ... [more]

CENAPRED reported that during 4-10 January steam-and-gas emissions rose from Popocatépetl; the plumes contained small amounts of ash during 4-5 January and 8-10 January. On 5 January two explosions generated incandescence in the crater. [more]

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.
