Fig. 4.From: Composition of volcanic gases emitted during repeating Vulcanian eruption stage of Shinmoedake, Kirishima volcano, JapanScatter plots showing correlation of concentrations of different species. The same dataset as on Fig. 3 are plotted. The data are plotted after correcting the sensor time-lag differences shown on Fig. 3. Grey thick lines are regression lines whose slope and error are also given in the figures. Figures (c) and (d) show a large scatter and two regression lines are drawn to cover the range of the estimated ratios.Back to article page
