Additional file 3 of A quest for unrest in multiparameter observations at Whakaari/White Island volcano, New Zealand 2007–2018

Additional file 3: Figure S3. Compilation of the different observables during the time period studied (a) lake level height above the outlet (cyan; Christenson et al. 2017) and percentage of lake level (dark blue; see Hamling, (2017; 2020) for a description) (b) fumarole F0 (dark blue) and lake temperatures (cyan, Christenson et al. 2017) (c) SO2 flux measured with a DOAS (light blue lines and smoothed using a Hodrick Prescott filter in brown) and with a Cospec (magenta circles) (d) CO2 flux (red circles and smoothed line) and CO2/SO2 ratios (green circles) (e) RSAM (filtered between 2 and 5 Hz) computed using the seismic data at WIZ (black circles and smoothed version using a Hodrick Prescott filter in cyan). Each tick on the x-axis corresponds to 1 January of each year. Roman numbers correspond to different periods of reference described in the Chronology section.
