Classification of long-term very long period (VLP) volcanic earthquakes at Whakaari/White Island volcano, New Zealand
Abstract We have observed very long period earthquakes (VLPs) over the period 2007 to the end of 2019 at Whakaari/White Island volcano, New Zealand. The earthquakes exhibit similitude between waveforms which suggests repeating source locations and processes. VLPs recorded at two permanent stations w...
