Santo Tomas is a stratovolcano with numerous volcanic vents and fissures (Philippines Commission of Volcanology, 1981). There was a report of an eruption or "displacement" in the region on 4 January 1641, described as an outburst of water accompanied by an earthquake. That is also the date of the major eruption of Parker volcano in southern Mindanao that impacted much of the Philippines. The Asin Hot Springs are about 12 km NNW of the summit, but their connection to the volcano is unknown.
The Global Volcanism Program is not aware of any Holocene eruptions from Santo Tomas. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Santo Tomas 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 Global Volcanism Program has no photographs available for Santo Tomas.
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.
