Diagrams showing the variation of selected major and trace elements plotted against SiO2 (wt.%) and Zr (ppm) respectively, together with selected incompatible trace element ratios for volcanic rocks erupted during the February–April 2017 activity. Compositions of the products erupted during the 2011–2013 activity at the NSEC6 and the 2015–2016 eruptions at VOR11 have been reported for comparison.
