Quantification of gas and solid emissions during Strombolian explosions using simultaneous sulphur dioxide and infrared camera observations

摘要: We present simultaneous measurements of gas and solid emissions from Strombolian explosions acquired on Stromboli volcano 30 September 2012 using an SO2 camera infrared camera. find no significant correlation between masses, consistent with the postulated independence processes controlling bubble film rupture slug mass, which determine emitted masses respectively. Our observations demonstrate utility multi-parametric imaging volcanic events at different wavelengths to elucidate relationships disparate processes. also further in quantifying explosion dynamics, that by combining ultra violet images spectral we are able image spatial distribution absorbance plumes and, crucially, calibrate total while compensating for light dilution effects.
