Aceh, Seulawah Agam Volcano


This forested peak is the most noticeable mountain near Banda Aceh. It has a large caldera, known as Lam Teuba, but it has not erupted since 1839. The traditional hiking route starts east of the peak, 2.5km north-west of Saree, which is itself one and a half hour’s drive (70km) from Banda Aceh. The hike can be done in one long day although there are places suitable for camping. There is a large cement pillar at the top.

Seulawah Agam at the NW tip of Sumatra is an extensively forested volcano of Pleistocene-Holocene age constructed within the large Pleistocene Lam Teuba caldera. A smaller 8 x 6 km caldera lies within Lam Teuba caldera. The summit contains a forested, 400-m-wide crater. The active van Heutsz crater, located at 650 m on the NNE flank of Suelawah Agam, is one of several areas containing active fumarole fields. Sapper (1927) and the Catalog of Active Volcanoes of the World (CAVW) reported an explosive eruption in the early 16th century, and the CAVW also listed an eruption from the van Heutsz crater in 1839. Rock et al. (1982) found no evidence for historical eruptions. However the Volcanological Survey of Indonesia noted that although no historical eruptions have occurred from the main cone, the reported NNE-flank explosive activity may have been hydrothermal and not have involved new magmatic activity.
