The small, triangular, 3-km-wide island of Uliaga, located at the NE end of the Islands of the Four Mountains archipelago immediately NW of Kagamil Island, is composed of a small, eroded stratovolcano. Uliaga volcano rises to only 888 m and is the smallest of the Islands of the Four Mountains volcanoes. There are no reports of historical eruptions from Uliaga, but the volcano was considered to have been active during the Holocene (Nye et al., 1998).

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

An eroded stratovolcano forms the small, trianglular, 3-km-wide island of Uliaga, located at the NE end of the Islands of Four Mountains archipelago immediately NW of Kagamil Island. Uliaga volcano rises to only 888 m and is the smallest of the "Islands of Four Mountains" volcanoes. Little is known geologically about this volcano, and there are no reports of historical eruptions.

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.
