Fig. 6From: Relating gas ascent to eruption triggering for the April 27, 2016, White Island (Whakaari), New Zealand eruption sequenceUnfiltered (blue) and filtered (red) displacement waveforms recorded at station WI04 for the large VLP just prior to eruption P4. The waveforms were band-pass-filtered between 0.03 and 0.1 Hz. Note the very-long-period noise/tilt present on the horizontal components, which makes the recovery of the static shift at these components impossibleBack to article page
