During the devastating April 1966 eruption, pyroclastic flows reached 9 km from the summit crater. These trees were blown down parallel to the travel direction of the pyroclastic flows near Bambingan, 5 km west of the crater. This 18 May 1966 photo shows Umbuk hill in the background and was taken about three weeks after the brief 26-27 April eruption that lasted about 7 hours.
