The VSI reported two explosions at Peuet Sague on 25 December, and another the next day. The explosions deposited ash over a wide area including villages 20 km from the summit. As of about 8 January lava flows were visible at the volcano from Trans village, 7 km away. The volcano is at Alert Level 2 (on a scale of 1-4).
Geologic Background. Peuet Sague is a large volcanic complex in NW Sumatra. The volcano, whose name means "square," contains four summit peaks, with the youngest lava dome being located to the N or NW. This extremely isolated volcano lies several days journey on foot from the nearest village and is infrequently visited. The first recorded historical eruption took place from 1918-21, when explosive activity and pyroclastic flows accompanied summit lava-dome growth. The active crater is located NE of the Gunung Tutung lava dome and has typically produced small-to-moderate explosive eruptions.
