Geological Summary

Larderello, one of the world's most productive geothermal areas, is located in the southern part of the Tuscany region of Italy. This extensive solfatara field lies in an area underlain by sediments of Eocene-to-Pliocene age. The geothermal activity is considered to be related to a cooling granitic pluton of Pliocene age beneath sedimentary and metamorphic rocks ranging from Paleozoic to Tertiary age, although the area is cut by faults with hydrothermal mineralization related to Pliocene-to-Quaternary Tuscan magmatism. The only surficial morphological manifestation of volcanism is a series of about a dozen explosion craters 30-250 m in diameter. The Lago Vecchienna crater, now filled by a 250-m-wide lake, ejected blocks and ash during a phreatic eruption in about 1282 CE (Marinelli, 1969).

Steam pours from cooling towers at Larderello, one of the world's most productive geothermal areas. Larderello is located in the Tuscany region of Italy, at a solfatara field in an area underlain by sediments of Eocene-to-Pliocene age. The only surficial morphological manifestation of volcanism is a series of about a dozen explosion craters 30-250 m in diameter. The youngest of these, the Lago Vecchienna crater, ejected blocks and ash during a phreatic eruption in about 1282 AD and is now filled by a 250-m-wide lake.

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.
