Fig. 7

Whole-rock chemical compositions of ejecta (P pumice, B ballistics, L: massive lava, and A ash) from four Shinmoedake eruptive events: 1717, 2008–2010, 2011, and 2017–2018. Dashed areas indicate bulk ash compositions during specific activity phases in 2017–2018. Arrows indicate bulk ash composition trends, throughout the 2017–2018 event toward the historical Shinmoedake magma composition. The shaded area in the SiO2–K2O diagram shows the typical magma composition trend since 1717
