There are no Holocene eruptions known for Forecast Seamount.

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.

Forecast Seamount lies about 70 km west of the southern tip of Guam and about 19 km NW of Seamount X. Hydrothermal fluid temperatures up to 200 degrees C, one of the highest temperature vent systems known in the Mariana arc, were measured during a 2006 NOAA expedition. Vent community species that occur on Forecast Seamount include shrimp, snails, limpets, crabs, sulfide worms, and scale worms, and differ from those further to the north in the Marianas arc.
