There are no Holocene eruptions known for Mount Morning. 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.

Mount Morning is a glaciated, undissected alkalic shield volcano in the Erebus volcanic province located SE of the south end of the Royal Society Range. An elongated 4.9 x 4.1 km wide caldera lies at the 2723-m-high summit, and numerous parasitic lava domes and flank cinder cones formed on fissures on the north, NE, and SE flanks. The latest volcanism associated with growth of the phonolitic central volcano was Potassium-Argon dated at about 1.2 to 1 million years, and late-Pleistocene to zero-age Argon/Argon dates were obtained for some of the volumetrically dominant basanitic fissure vents. More than 50 mophologically youthful flank vents occur on the flanks of Mount Morning.
