There are no Holocene eruptions known for Mandalagan. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

The deeply dissected, dominantly andesitic-to-dacitic Mandalagan volcanic complex on northern Negros Island contains a vigorous solfataric area at a highly altered domed structure. The complex consists of seven volcanic centers, including at least five craters and/or calderas up to 2 km in diameter. One solfataric area emits a high-temperature (106 degrees C) plume to 30 m height with a roaring noise like a high-pressure geothermal borehole. The age of the most recent eruptive activity at the 1885-m-high volcano, which produced a thin basaltic lava flow, is not known.
