Geological Summary

The Quimsachata (Kimsachata) volcano group, the northernmost young volcanoes in Peru, consist of two late-Pleistocene and Holocene monogenetic volcanoes lie at the foot of the Cordillera Oriental in an isolated area far east of the main volcanic front. Quimsachata is a high-potassium andesitic scoria cone surrounded by a compound lava shield that was erupted in flat terrain along the Vilcanota River about 11,500 years ago. Oroscocha is a rhyolitic lava dome with a short, thick lava flow erupted from a N-S-trending fissure about 6400 years ago.

The dark-colored lava flow just to the right and below the center of this NASA Landsat image (with north to the top) originated from the Quimsachata (Kimsachata) scoria cone about 11,500 years ago. The smaller lava flow directly to the north that deflects the E-W-trending Vilcanota River was erupted from the Oroscocha lava dome about 6400 years ago. These are the northernmost young volcanic centers in Perú and lie at the foot of the Cordillera Oriental in an isolated area far east of the main volcanic front.

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.
