Geological Summary

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.

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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
