Sulfur dioxide (SO2(g)) is an important gas species in most common volcanic settings on Earth including subduction zones (Shinohara 2013). The relative abundances of SO2(g) may vary at a volcano over time with the highest rates of SO2(g) emissions occurring during eruptive degassing and lesser amounts emitted continuously during quiescent degassing, resulting in a large total amount of SO2(g) integrated over time of the order of 10 Mt/a (McCormick et al. 2013; Shinohara 2013; Henley and Hughes 2016). Much of the emitted SO2(g) is released at high temperatures....
