An 8 year volcanic SO2 emission inventory for 2005–2012 is obtained based on satellite measurements of SO2 from OMI (Ozone Monitoring Instrument) and ancillary information from the Global Volcanism Program. It includes contributions from global volcanic eruptions and from eight persistently degassing volcanoes in the tropics. It shows significant differences in the estimate of SO2 amount and in...

New H2O, CO2 and S concentration data for basaltic glasses from ‘hotspot’, with temperature differences of 200°C or more between hotter upwelling plumes and the ambient mantle Loihi seamount, Hawaii, allow us to model degassing, assimilation, adiabat (e.g. White & McKenzie, 1989; Campbell, 1998; and the distribution of major volatiles within and around the Davies, 1998). In contrast, it has lon...

To investigate the relationship between volatile abundances and eruption style, we have analyzed major element and volatile (H2O, CO2, S) concentrations in olivine-hosted melt inclusions in tephra from the V2000 yr BP eruption of Xitle volcano in the central Trans-Mexican Volcanic Belt. The Xitle eruption was dominantly effusive, with fluid lava flows accounting for V95% of the total dense rock...

Purpose. To develop methods for calculating of the expediency to use mine degassing system, made current composites, improve safety in heavily loaded longwalls. Methodology. Solving problems involved analysis studies concerning methane-air mixture removal from stopes while mining gaseous coal seams. Standard schemes gas transmission systems have been considered as well peculiarities transportat...
