Bukit Amasing (Amasing Hill) is the largest and NW-most of a group of three small andesitic volcanoes of Holocene age (Yasin, 1980). They are located along a NW-SE line on central Bacan Island, west of the southern tip of Halmahera. Two smaller volcanoes, Cakasuanggi and Dua Saudara, were constructed to the SE, north of the metamorphic complex of the Sibela Mountains. These mountains separate the Amasing volcano group from another group of three andesitic Holocene volcanoes in SE-most Bacan Island.

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

Bukit Amasing (Amasing Hill) is the largest and NW-most of a group of three small andesitic volcanoes located just above the center of this NASA Landsat image (with north to the top). These volcanoes lie along a NW-SE line in central Bacan Island. Two smaller volcanoes, Cakasuanggi and Dua Saudara, were constructed to the SE, north of the metamorphic complex of the Sibela Mountains, the cloud-covered massif at the bottom center. Other young volcanoes of the Bibinoi group lie at the SE peninsula of Bacan Island (lower right).

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.
