The elongated island of Motlav, also referred to as Mota Lava, is comprised of at least five Pleistocene basaltic stratovolcanoes capped by two well-preserved late-Pleistocene to Holocene pyroclastic cones, Tuntog and Vetnam. Tuntog is a largely pyroclastic composite cone at the SW end of the island with a 500-m-wide summit crater. Vetman, in the center of the island, is a pyroclastic cone truncated by a summit crater that is breached on the southern side. The 411-m high point of Motlav is a remnant of older volcanics along the central ridge of the 12-km-long, NE-SW-trending island.

The Global Volcanism Program is not aware of any Holocene eruptions from Motlav. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Motlav 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.

The elongated island of Motlav, also referred to as Mota Lava, lies in the northern Banks Islands of Vanuatu. The 12-km-long island is comprised of at least five Pleistocene basaltic stratovolcanoes capped by two well-preserved late-Pleistocene to Holocene pyroclastic cones, Tuntag and Vetnam. The low peak with a shadow above it at the lower left (SW) part of the island is Tuntog, a largely pyroclastic composite cone with a 500-m-wide summit crater. Vetnam pyroclastic cone lies in the center of the island.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
