Geological Summary

Masaraga is a sharp-topped, forested stratovolcano that rises to 1328 m NW of Mayon volcano. Thick lava flows occur on the flanks of this andesitic-to-ryholitic volcano. Masaraga was classified as Holocene by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI, 1973), and K-Ar dates of zero age were obtained from this volcano.

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

Masaraga is a sharp-topped forested stratovolcano that rises to 1328 m NW of Mayon volcano. This view from near the summit of Mayon also shows Mount Iriga (upper right), with its large breached crater. Little is known of the geologic history of Masaraga volcano.

Forested Masaraga volcano, seen here from the south, is a 1328-m stratovolcano NW of Mayon volcano. An eroded volcanic ridge extends to the NW from Masaraga. Thick lava flows occur on on the flanks of Masaraga, but little is known of its geologic history.

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.
