Seismic precursors to the Whakaari 2019 phreatic eruption are transferable to other eruptions and volcanoes
Volcanic eruptions that occur without warning can be deadly in touristic and populated areas. Even with real-time geophysical monitoring, forecasting sudden eruptions is difficult, because their precursors are hard to recognize and can vary between volcanoes. Here, we describe a general seismic prec...
