The low-lying Sessagara Hills, located near the mouth of the Uiaka River, south of Collingwood Bay, is a small alkalic andesitic volcanic field in eastern Papua New Guinea. The age of the most recent eruption is not known, although the field clearly included Holocene volcanic activity (Smith, 1981). Two of the cones north of the Goropu Mountains display preserved summit craters and were probably active during the Holocene; other cones may be of Pleistocene age.

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