Fig. 6

Chemical compositions of melt inclusions in products from the 1235, 1716–17, 2011 and 2018 eruptions. a Al2O3 vs. SiO2 contents; b MgO vs. SiO2 contents; c CaO vs. SiO2 contents; and d K2O vs. SiO2 contents. Large circles with error bars indicate chemical compositions of the groundmasses and the standard deviations, respectively (also shown in Fig. 4). Chemical compositions of groundmasses from the 2011 eruptions (2011-1PP, 2011-2SGP, 2011-2SWP, 2011-3SGP, 2011-4VB, 2011-5VL, 2011-6VA, 2011-7VL, 2011-8A, and 2011-9A) are denoted by gray circles. Chemical compositions of groundmasses from the 2018 eruptions (2018-1VGP, 2018-1VS, 2018-2VGP, 2018-2VS, and 2018-4L1 to L3) are represented by light red circles. Chemical composition of groundmasses in the form of gray pumices from 1716–17 are open circles. Whole-rock chemical compositions of products from the 2011 and 2018 eruptions and previous eruptions are also shown using the same symbols as in Fig. 4. Chemical compositions of melts (M1 and M2 magmas at pressure ranges of 50–500 MPa and F1, F2, A1, A2, B1, and B2 magmas at pressure ranges of 50–200 MPa) calculated using the MELTS program (Additional file 9) are also shown
