Popocatépetl volcano (Central Mexico) activity update: frequent small explosions with ash up to 1.5 km altitude, crater glow, strong SO2 emission

The number of explosions has been increasing. During 15-16 Oct, 71 were recorded by CENAPRED. Some of these produced ash plumes rising up to 1.5 km above the crater, notably at 18:05 h local time on 15 Oct, 04:39 h and 09:43 h on 16 Oct.
Glow is visible above the crater at night, and a SO2 plume is visible regularly on NOAA's satellite images.

SO2 plume from Popocatépetl on October 14, 2012 (NOAA)
Monday, Oct 15, 2012
The number of explosions is on the increase again. CENAPRED recorded 48 exhalations of low to medium intensity during 14-15 Oct, some of which were accompanied by small emissions of ash. The largest produced plumes rising 1.5 km above the crater. ... [more]
Ash emission on 14 Oct
Sunday, Oct 14, 2012
23 exhalations of low to medium intensity with steam and sometimes ash emissions occurred during 13-14 Oct, the most important at 19:01 pm local time on 13 Oct and at 09:57 h today. The latter produced a column that moved 1.5 km west-southwest and was noted by VAAC. ... [more]
Ash explosion at 11:16 on 10 Oct
Thursday, Oct 11, 2012
The explosion frequency and size has been increasing over the past 2 days. ... [more]
Steam emission from Popocatépetl this morning
Monday, Oct 08, 2012
Activity has been very low compared to previous days. During the last 24 h, 4 low-intensity exhalations occurred and were accompanied by weak continuous emission of water vapor and gas. During the night, incandescence was observed on the crater. Additionally, yesterday at 17:32 h local time, a volcanic quake of magnitude 1.2 occurred. [more]
SO2 plume from Popocatépetl on 6 Oct 2012 (NOAA)
Sunday, Oct 07, 2012
No significant changes in activity: 18 weak explosions occurred between 5-6 Oct and the volcano produces a strong SO2 plume. [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.
