Detecting and Locating Precursory Signals During the 2011 El Hierro, Canary Islands, Submarine Eruption

Forecasting and monitoring submarine volcanic eruptions represent a particular challenge due to the lack of direct surface observations. In the present study, we investigate the dynamics of the 2011 El Hierro submarine eruption using phase autocorrelation and cross-correlation from 2 years of contin...
