Table 3 Number of breaks ascribable to sources other than earthquakes. From left to right: total number of breaks detected by AIC method (\(\Delta t\) = 60 min, \(Th_{\mathrm{A}}\) = 3 TECU/h, \(Th_{\mathrm{R}}\) = 75%), number of breaks removed after each of the three steps, the overall percentage of ‘explained’ breaks.
