Geological Summary

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 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 morphologically youthful flank vents occur on the flanks.

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

Mount Morning shield volcano is seen in this aerial view from the NE. An ice-filled, elongated 4.9 x 4.1 km wide caldera lies at the 2723-m-high summit of the volcano. Numerous parasitic lava domes and flank cinder cones formed on fissures on Hurricane Ridge cutting across the NE flank at the middle right and on the Riviera Ridge beyond on the north flank.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
