Geological Summary

The conical, glacier-clad Nevado de Longaví volcano is a late-Pleistocene to Holocene, dominantly andesitic stratovolcano constructed over a basement of Tertiary volcaniclastic and granitic rocks. Two edifice-collapse events modified the eastern and SW flank of a pre-Holocene volcano, and Holocene activity has been concentrated at the summit region and on the eastern flanks of the volcano. Andesitic-to-dacitic lava domes occupy the summit region, and a Holocene dome forms the 3242-m-high summit of Longaví. The last eruptions produced a lava dome in the upper part of the collapse scarp and summit region that partially collapsed to the east, forming block-and-ash flow deposits. No historical eruptions are known, although fumarolic activity continues.

The conical, glacier-clad Nevado de Longaví volcano is seen from the SE. In the foreground is a Holocene block-and-ash flow deposit. This late-Pleistocene to Holocene andesitic stratovolcano was constructed over a basement of sedimentary and granitic rocks. A small lava dome forms the 3242-m-high summit of Longaví. No historical eruptions are known, although fumarolic activity continues.

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.
