The 10-km-wide Herbert Island, the SW-most of the Islands of the Four Mountains group, lies across a strait SW of Mount Cleveland. Herbert is a classic, symmetrical stratovolcano whose summit is broadly truncated by a 2-km-wide caldera that is breached to NW. No historical eruptions have been recorded from 1280-m-high Herbert volcano, which, like many other Aleutian volcanoes, has not been studied geologically.
The Global Volcanism Program is not aware of any Holocene eruptions from Herbert. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Herbert page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Herbert.
|Herbert Island, capped by the snow-covered peak in the right foreground, is a classic, symmetrical stratovolcano with a 2-km-wide summit caldera that is breached to NW. No historical eruptions have been recorded from 1280-m-high Herbert volcano, which, like many other Aleutian volcanoes, has not been studied geologically. This June 23, 1987, view from the WSW shows a steam plume originating from conical Cleveland volcano in background, whose slopes are darkened by ashfall from an eruption that began on June 19.

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.
