The Global Volcanism Program has no Bulletin Reports available for Forecast Seamount.

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.

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

Map showing the location and topography of Forecast Seamount and Seamount X. The bathymetry data are a combination of bathymetry collected on NOAA expeditions in 2004 and 2006, and the contour interval is 200 meters. Grid cell size is 50 meters.

A view from a submersible during a 2006 NOAA Vents Program expedition shows a glimpse of a biological community at a Forecast Seamount vent site. The species that occur here and in the Mariana backarc spreading center differ from those on the seamounts of the Mariana arc to the north. Hydrothermal fluid temperatures up to 200 degrees C, one of the highest temperature vent systems known in the Mariana arc, were measured.

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.
