摘要

We investigated the dynamics of the continuous seismic signal recorded before and during the 2011-2012 El Hierro eruption (Canary Islands) using the innovative approach of the Fisher-Shannon method, a suitable statistical tool for detecting dynamic changes in complex systems. Our findings identify dynamic changes in the seismic signal that can be correlated with different stress states of the magmatic setting and the plumbing system in the volcano at El Hierro. The results contribute to the understanding of the fracturing pattern in the crust during a new intrusion and eruption of an overpressurized batch of magma.
