There are no Holocene eruptions known for Crater Mountain. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

Crater Mountain, an arcuate chain of peaks 3000 m or more in height, is extensively eroded to the point that its volcanic origin is almost unrecognizable. However, steep-sided valleys to the north and east are floored by lava flows and other young volcanic features. The easternmost Agotu Valley contains several small craters, cinder cones, and maars of late-Pleistocene or Holocene age (Mackenzie and Johnson, 1984). Several small cones, lava domes, and associated lava flows north and NW of the Erun Anticline may in part be Holocene in age.
