View of the active flow area on the flank of Kilauea. Note how the lava drains from below a solidified crust. Radiating heat into the air above the hot flow creates a distorted view of flows in the distance. The dark area in the upper center is a small a'a flow descending amongst the pa'hoe'hoe flows. A'a forms when a lava flow has cooled enough that a thick crust of lava blocks congeal, break apart, and may mix and move with the still-partly-molten flow.
