Popocatépetl volcano (Central Mexico) activity update: occasional small explosions, strong steaming
Monday Aug 20, 2012 12:05 PM | BY: T
The stronger explosions on 18 and 19 Aug produced ash plumes and ejected incandescent bombs, such as the ones at 11:16, 15:35, 16:34, 17:44 and 20:52 local time on 18 Aug and one at 04:36 on 19 Aug.
A strong SO2 plume was visible on yesterday's NOAA SO2-monitoring satellite image.

A sharp increase in activity has been observed at Popocatépetl since yesterday. During 17-18 August, 176 mostly small explosions were observed (compared to values of 10-20 for the previous week), and 74 alone during the following 9 hours, i.e. about 1 every 8 minutes. ... [more]

Activity remains low. About 1 weak eruption per hour has been observed during the past day by CENAPRED. SO2 emissions remain high (which is typical for Popo during phases of activity). [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.
