The Global Volcanism Program is not aware of any Holocene eruptions from Corvo. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Corvo 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.
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Caldiera||Caldera||718 m||39° 40' 0" N||31° 4' 0" W|
|A 2-km-wide caldera containing several small cinder cones and two shallow lakes is the most prominent feature in this NASA Space Shuttle image of Corvo Island with north to the left. Two pyroclastic cones erupted along a N-S-trending fissure outside the caldera fed lava flows that formed a platform that underlies the peninsula at the southern end of the island. The 3.5 x 6 km island of Corvo and its neighbor to the south, Flores (far right), are the only two Azorean volcanoes located west of the Mid-Atlantic Ridge.

|Agricultural fields line much of the walls of a 2-km-wide caldera centered on the north side of Corvo Island. The caldera floor contains several small cinder cones and two shallow lakes. The small 3.5 x 6 km island of Corvo is located at the NW end of the Azores archipelago, and along with Flores, are the only two Azorean volcanoes located west of the Mid-Atlantic Ridge. The youngest eruption on Corvo produced a fissure-fed lava flow that reached the sea near Punta Negra.

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.

|WOVOdat||WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
