Estimates of ETAS model (1) and non-stationary ETAS model (3). The models are fitted to a seismicity of M ≥ 1.0 in the R3, R4, R5, and R8 subregions, given from the top to bottom row. The first and second columns show the empirical (black) and theoretical (red) cumulative curves of the ETAS fitted to the data against the ordinary and transformed times of the ETAS model in the target period prior to the most significant change-point of the two-stage ETAS model. Beneath the empirical cumulative curves, the thick dashed light blue curves indicate the theoretical cumulative curves of the non-stationary ETAS model. The third column shows μ(t) in red and K 0(t) in blue with twofold errors estimated using non-stationary ETAS model (3). The rightmost panels show the spatial distribution of K 0(t) versus the locations of the earthquakes
