Popocatepetl volcano, 21 November 2009 (CENAPRED)

Popocatépetl volcano had an active 24 hours over 21 and 22 November, reports CENAPRED, Mexico’s Centro Nacional de Prevención de Desastres (CENAPRED bulletins for November can be found by searching via this archive page). A magnitude 2 volcano-tectonic earthquake was recorded and there were four small eruptive events during the 24 hours preceding 11:00 local time on 22 November, the most significant of which, occuring at 18:31 local time on 21 November, produced an ash column of 3.5 km altitude. The image above, from CENAPRED’s Popocatépetl webcam to the north of the volcano, shows the situation at 18:38 local time, with incandescence and ash emissions clearly visible.

Ashfall was reported to the north and east, across the state of Tlaxcala. The Mexican press (see links below) reports that ash covered vehicles and roads in 38 municipalities in Tlaxcala, but that ash quantities were ‘minor’ and that no problems resulted. Following this event, CENAPRED reports that the volcano returned to its normal conditions.
