Geological Summary

The Gayolesten fumarole field is located on the flanks of the Pleistocene Gunung Kembar volcano. The Kembar complex, located at the junction of two fault systems, is an andesitic shield volcano capped by a complex of craters and cones (Cameron et al. 1982). Gayolesten was included in the Catalog of Active Volcanoes of the World (Neumann van Padang 1951) based on its geothermal activity. Active fumaroles and hot springs are present at several locations.

The Global Volcanism Program is not aware of any Holocene eruptions from Kembar. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Kembar page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Kembar volcano, the small forested peak at left-center, is seen in this aerial view from the north. The Gayolesten fumarole field is located on the flanks of the Pleistocene Gunung Kembar volcano. Active fumaroles and hot springs are present at several locations. The Kembar complex, located at the junction of two fault systems, is an andesitic shield volcano capped by a complex of craters and cones. The parallel trace of the major Sumatra fault system forms the valley diagonally cutting across the image to south of Kembar.

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.
