Fig. 3: Stress parameters of Campi Flegrei earthquakes.
From: Earthquake rupture velocity and stress drop interaction in the Campi Flegrei volcanic caldera
Three independent measured stress released parameters, a apparent stress \({\tau }_{a}\), b Arms stress drop \({\varDelta \sigma }_{{aRMS}}\), and c static stress drop \(\Delta \sigma\) versus the seismic moment (bottom axis) and moment magnitude (top axis). d comparison of the bin-averaged values for \({\tau }_{a}\), \({\varDelta \sigma }_{{aRMS}}\), and \(\Delta \sigma\). Freedman–Diaconis rule51 is used to bin the data.
