A quest for unrest in multiparameter observations at Whakaari/White Island volcano, New Zealand 2007–2018
Abstract The Whakaari/White Island volcano, located ~ 50 km off the east coast of the North Island in New Zealand, has experienced sequences of quiescence, unrest, magmatic and phreatic eruptions over the last decades. For the last 15 years, seismic data have been continuously archived providing pot...

By combining our new set of observations with the long-term evolution of earthquakes, deformation, visual observations and geochemistry, we review the activity of Whakaari/White Island between 2007 and the end of 2018.

We finally put these results in the wider context of forecasting phreatic eruptions using continuous seismic records.
