In mid-November 1944 lava broke out of the SSW base of the cone, below the south vent in the crater. Fresh black lava pours from the new vent in this view from the south. The Ahuán flow advanced over the earlier Taquí flows in the foreground. A small lava dike was exposed in the wall of the cone a short distance above the vent. Ahuán flows traveled around the east side of the cone to the north.
