Fig. 7From: A quest for unrest in multiparameter observations at Whakaari/White Island volcano, New Zealand 2007–2018Comparison DSAR (green) and percentage of lake level (blue) relative to full, i.e., elevated values correspond to higher lake levels (Hamling 2017). See Fig. 4 for the description of the vertical lines corresponding to key time periods. The 1-day DSAR data have been smoothed with a Hendrick Prescott filter, which prevents temporal aliasing (parameter = 104)Back to article page
