“…Moreover the analysis of the emitted gas species from degassing plume is usually performed trough ground networks of instruments based on the spectral behaviour of the gas species, although many volcanoes in the world do not have such permanent networks. The ASI-SRV system will produce information on the concentration and flux of sulphur dioxide (SO2) [Realmuto et al, 1994] water vapour and volcanic aerosol optical thickness [Spinetti et al, 2003] by means of ASTER, MODIS and HYPERION data on Etna test site. The analysis of ash clouds will be made by means of already consolidated procedures [Searcy et al, 1998, Corradini et al, 2006, Constantine et al, 1999 which uses low spatial resolution sensors with an high revisit time (eg.…”

“…The VAOT has been developed at INGV [Spinetti et al, 2003, Spinetti et al, 2004, Spinetti and Buongiorno 2007, and represents the first algorithm that has been developed following the theoretical basis of atmospheric aerosol estimated from space, published by ] Purpose of this algorithm is the estimation of the volcanic aerosol optical thickness (AOT) during the prevention and early warning phase therefore VAOT technique has been used in ASI-SRV to estimate AOT at medium-high resolution in early warning phase. The algorithm to estimate the AOT parameter is based on the inversion of the radiative transfer equation using the 6S ] radiative transfer code.…”

“…The analysis of these IR images allowed to detect, for the first time, the separation between SO 2 and volcanic ash. In addition, AVHRR images are elaborated by INGV, CNT-LABTEL of Rome for monitoring Etna volcanic plumes (Spinetti and Buongiorno, 2007) and delivered to INGV-CT every day.…”

Abstract. In this paper we describe the results of a project ongoing at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The objective is to develop and implement a system for monitoring and forecasting volcanic plumes of Etna. Monitoring is based at present by multispectral infrared measurements from the Spin Enhanced Visible and Infrared Imager on board the Meteosat Second Generation geosynchronous satellite, visual and thermal cameras, and three radar disdrometers able to detect ash dispersal and fallout. Forecasting is performed by using automatic procedures for: i) downloading weather forecast data from meteorological mesoscale models; ii) running models of tephra dispersal, iii) plotting hazard maps of volcanic ash dispersal and deposition for certain scenarios and, iv) publishing the results on a web-site dedicated to the Italian Civil Protection. Simulations are based on eruptive scenarios obtained by analysing field data collected after the end of recent Etna eruptions. Forecasting is, hence, supported by plume observations carried out by the monitoring system. The system was tested on some explosive events occurred during 2006 and 2007 successfully. The potentiality use of monitoring and forecasting Etna volcanic plumes, in a way to prevent threats to aviation from volcanic ash, is finally discussed.

“…Italy has many active volcanoes that are continuously monitored by the networks of instruments held by the Istituto INGV has been using hand-held thermal cameras since 2001 during both ground-based and helicopter-borne surveys for the surveillance and monitoring of Mt. Etna, Stromboli, Vulcano, Campi Flegrei and Vesuvius activity [3,[12][13][14][15][16][17]. Indeed air-borne surveys provide information crucial to get an overall view of the eruptive scenarios, especially in the case of wide active areas such as lava flow fields, crater fumaroles and hydrothermal zones [18].…”

Extreme environments like active volcanoes exhibit many difficulties in being studied by in situ techniques. For example, during eruptions, summit areas are very hard to be accessed because of logistics problems and/or volcanic hazards. The use of remote sensing techniques in the last 20 years by satellite or airborne platforms has proven their capabilities in mapping and monitoring the evolution of volcanic activity. This approach has become increasingly important, as much interest is actually focused on understanding precursory signals to volcanic eruptions. In this work we verify the use of cutting-edge technology like unmanned flying system thermally equipped for volcanic applications. We present the results of a flight test performed by INGV in collaboration with the University of Bologna (Aerospace Division) by using a multi-rotor aircraft in a hexacopter configuration. The experiment was realized in radio controlled mode to overcome many regulation problems which, especially in Italy, limit the use of this system in autonomous mode. The overall goal was not only qualitative but also quantitative oriented. The system flew above an Italian mud volcano, named Le Salinelle, located on the lower South West flank of Mt. Etna volcano, which was chosen as representative site, providing not only a discrimination between hot and cold areas, but also the corresponding temperature values. The in-flight measurements have been cross-validated with contemporaneous in-situ acquisition of thermal data and from independent measurements of mud/water temperature.
