A quest for unrest in multiparameter observations at Whakaari/White Island volcano, New Zealand 2007–2018
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 potential in...
