This photo was taken the day after devastating pyroclastic flows swept down the south flank of Merapi in 1994. The lighter area to the left shows where the pyroclastic flows descended the flank. The darker-brown areas to the right of the pyroclastic-flow deposits are trees that were scorched by pyroclastic surge clouds. Sixty-four people were killed by these pyroclastic surges in a village near the location of this photo.
