Most Recent Bulletin Report: March 1990 (BGVN 15:03)


No signs of recent activity

January 1990 fieldwork revealed no fumarolic ice towers or other signs of recent activity. A thick (<=4 m) sequence of tephra was found in blue ice at the foot of the volcano, but its vertical attitude suggested eruptions thousands of years ago.

Mount Waesche is the southernmost of a N-S-trending chain of volcanoes in central Marie Byrd Land. Mount Waesche is located 20 km SW of Pliocene Mount Sidley, Antarctica's highest volcano, and was constructed on the SE rim of the 10-km-wide Chang Peak caldera. Pre-caldera Chang Peak lavas were erupted about 1.6 million years ago (Ma) and the Waesche shield formed about 1.0 Ma. Waesche may have been active during the Holocene and is a possible source of ash layers in the Byrd Station ice core that were deposited during the past 30,000 years. The youngest lavas are too young to date by Potassium-Argon. Satellitic cinder cones, some aligned along radial fissures, are located on the SW flank.

The Global Volcanism Program is not aware of any Holocene eruptions from Waesche. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Waesche 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 Waesche, seen here from the SW, is the southernmost of a N-S-trending chain of volcanoes in central Marie Byrd Land. Mount Waesche is located 20 km SW of Pleistocene Mount Sidley, Antarctica's highest volcano. Waesche may have been active during the Holocene and is a possible source of ash layers in the Byrd Station ice core that were deposited during the past 30,000 years. Satellitic cinder cones, some aligned along radial fissures, are located on the SW flank.

Satellitic cinder cones on the flank of Mount Waesche are composed of black, vesicular lava flows and ejected pyroclastic material of basaltic composition. Numerous pyroclastic cones, some erupted along radial fissures, cover a broad area on the SW flank of Mount Waesche.

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.
