The paper represents a very detailed study of the geophysical precursors recorded before and during a major recent explosive eruption. Moreover, the results permit to partly validate and discuss recent models of volcano unrest and have large applications for the monitoring of hazardous volcanoes worldwide.
Short summary
Infrequent eruptions of acidic magma are one of the most dangerous natural phenomena, but almost none of them have been witnessed by modern science. We present the first systematic characterization of seismicity recorded near an erupting acidic volcano (Cordón Caulle 2011). We define different phases of unrest and eruption, which combined with previous findings allows us to discuss the main processes associated with this type of violent eruption, with implications for their volcanic hazard.
