The western flank of Popocatépetl is seen here in November 1994, a little more than a month prior to its eruption on 21 December 1994. A faint gas plume is dispersing to the NE by predominant winds. The peak halfway down the left flank is Ventorrillo, a remnant of an older volcanic center preceding the construction of the modern edifice.
