There are no Holocene eruptions known for Sessagara. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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.

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.
