Geological Summary

The monogenetic Huambo volcanic field lies SSE of the Andahua-Orcocampo volcanic field, west of Sabancaya volcano. The Huambo volcanic field is divided into two segments. The southern area contains several cinder cones and associated lava flows, some of which are inferred to be of early to late-Holocene age on the basis of morphological criteria. The northern part contains a single vent, the Cerro Keyocc cinder cone, which produced an extensive lava field that blanketed a plateau to the west during an eruption radiocarbon dated at about 2650 years ago.

Photo Gallery

The dark-brown area just north of the elongated black lake at the center of this NASA Landsat image is a lava flow from the northern segment of the Huambo volcanic field. The flows were erupted from the Cerro Keyocc cinder cone about 2650 years ago. The southern part of the volcanic field, the dark-brown area at the SW part of this image, contains several cinder cones and associated lava flows, some of which are inferred to be of early to late-Holocene age. The large glacier-covered massif to the east is the Sabancaya volcanic complex.

WOVOdat WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

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.
