Popocatépetl volcano (Central Mexico) activity update: slight increase of activity
Sunday Sep 16, 2012 14:05 PM | BY: T
The more energetic explosions were on at 12:36 h, 20:12 h, 22:13 h and 22:47 h local time on 14 Sep and at 06:50 h yesterday, and produced small ash plumes rising up to 1 km.
Episodes of volcanic tremor occurred as well, the observatory notes.

Weak steam and sometimes ash explosions continue about every 2-3 hours. Otherwise, a strong steam plume is being emitted and satellite imagery show that there is still a lot of SO2 production from the volcano. At night, glow from the crater is visible, suggesting that the lava dome continues to grow slowly. [more]

A strong SO2 plume could be seen on NOAA's satellite image yesterday. The activity remains stable and at low levels. CENAPRED reports steaming and about 10 small explosions per day. [more]

10 weak explosions were registered during the past 24 hours, but it was not possible to see whether they contained ash. The largest were at 20:01h, 20:42h yesterday and this morning at 10:39h local time. CENAPRED also recorded weak tremor pulses and some small quakes are visible on the current seismogram. [more]

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. [more]

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. [more]
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.
