Pulau 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.

The Global Volcanism Program is not aware of any Holocene eruptions from Pulau Weh. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Pulau Weh page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Pulau Weh, with its irregular shoreline, is the right-hand island in this NASA Space Shuttle image with the north to the upper right. The NW tip of Sumatra is at the bottom of the image. Lhok Perialakot bay at the north side of the island has been interpreted as the remains of a partially collapsed older center breached to the NW and filled by the sea. Volcanism was assumed to be of Pleistocene age, but fumaroles and hot springs are found at the SE part of the island and along the shores of Lhok Perialakot.

The elongated island of Pulau Weh lies off the NW tip of Sumatra. It has been interpreted as the remains of a partially collapsed older center breached to the NW and filled by the sea. Volcanism at Pulau Weh was considered to be of Pleistocene age, 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.
