The Global Volcanism Program has no Bulletin Reports available for St. Michael.
The St. Michael volcanic field, at the south end of Norton Sound, covers all of St. Michael and Stuart Islands with more than 55 cones and craters. Broad low shield volcanoes underlie the younger cones, and maar volcanoes are located at the SW part of the volcanic field, which covers >3000 sq km and extends inland along the Golsovia and Kogok rivers. The youngest activity is of Holocene age, and native tradition says that a village was submerged by lava three times.
The Global Volcanism Program is not aware of any Holocene eruptions from St. Michael. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the St. Michael 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.

|The St. Michael volcanic field consists of more than 55 cones and craters occupying Stuart Island (upper left), St. Michael Island (forming the apparent peninsula at left-center, and areas inland. Broad low shield volcanoes underlie the younger cones, and maar volcanoes are located at the SW part of the volcanic field, which covers >3000 sq km. Light-colored young lava flows can be seen at the lower right originating from "The Sisters" area. Native tradition says that a village was submerged by lava three times.

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.
