BackgroundPulau Weh island off the NW tip of Sumatra has been interpreted as the remains of a partially collapsed older center breached to the NW and filled by the sea. Pulau Weh was included in the Catalog of Active Volcanoes of the World (Neumann van Padang 1951) based on its geothermal activity. Volcanism was assumed to be of Pleistocene age (Bennett et al., 1981), but fumaroles and hot springs are found a NW-E-trending line along the summit of the island and near the western shore of Lhok Perialakot bay on the northern side of the island.
