Abstract

In this paper we describe the results of satellite monitoring of Mount Etna on Sicily from January to December 2015. According to data of The National Institute of Geophysics and Volcanology (Italy), INGV, there were three strong eruptions of Etna (31 January, 13 May and 03 December 2015). Satellite data of the retrieved concentration of sulphur dioxide was used for monitoring. The data was obtained from OMI instrument (Ozone Monitoring Instrument, AURA satellite) measurements in the ultraviolet band. According to OMI instrument data, the distribution maps of SO2 concentration in the atmosphere (up to 7 km and up to 17.5 km) were created, as well as maps of Aerosol Index values (AI). As a result of the analysis of the obtained SO2 concentration maps, the maximum concentrations of SO2 were recorded during the eruption of the Mt.Etna in the atmosphere at an altitude of up to 7 km and up to 17.5 km. The results of monitoring of strong Etna eruption (03 December 2015) showed exceeded sulfur dioxide concentrations on the next day (04 December 2015). We traced the Southeast propagation direction of SO2 cloud from the volcano. On 05 December 2015, SO2 cloud was recorded in the layer of up to 7 km above the territory of Egypt, but with a lower concentration.
