Sulfur dioxide flux observed during the 2011 Shinmoedake volcano eruption. Solid circles show average SO2 flux of the observation day. Error bars show the range of the SO2 flux observed on the day. Solid lines show estimated daily SO2 flux calculated based on the observed SO2 flux (solid circles) and other information (see the text). (a) Sulfur dioxide flux between January 2011 and March 2012. (b) Sulfur dioxide flux during January –March 2011. The sub-Plinian eruption, lava accumulation and CV stages are shown with dashed lines.
