Popocatépetl volcano (Mexico): moderately strong explosion on 6 Aug, ash to 9 km altitude

CENAPRED reports 9 small to moderate explosions during 11-20:00 on 6 Aug.
The largest of these was relatively powerful and occurred at 17:58 local time. It produced an ash and steam plume 4.5 km height and thus reaching flight level 300 (30,000 ft / 10 km altitude). The plume drifted SW and possibly caused light ash fall in that direction.
The Washington VAAC reports that the ash in the upper layers at 30,000 ft quickly dissispated, but maintains an alert for ash at flight level 230 (23,000 ft or 7 km altitude).
At night, a strong glow is visible from the summit.

Popocatépetl's activity is relatively low. Only 14 weak emissons of mostly steam were recorded on 31 July during 24 hours, and there appears to be no significant seismic activity. Glow is still visible from the summit, but less than before. [details]

SO2 plume from Popocatépetl on 29 July (NOAA)
lundi, juil. 30, 2012
Eruptive activity remains reduced at Popocatepetl, but the volcano continues to emit a significant amount of SO2, and volcanic tremor and lava glow are visible. In fact, Popo is known to be one of the top-performers of SO2 emission among all known volcanoes. [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.
