(a) YP21 nonparametric distance corrections (−log(A0)n, open squares) and the 95% confidence intervals from 1000 bootstrap replications (gray‐shaded region). Distance corrections of Richter (1958) distance corrections (R58, solid triangles) are shown for reference. R is hypocentral distance (Rhyp) for the YP21 corrections and epicentral distance for the R58 corrections. (b) A closer view of the YP21 distance corrections, with a bilinear geometric spreading model plotted for comparison along with Luckett et al. (2019), L19, parametric attenuation curves. The breakpoint of the hypothetical bilinear geometrical spreading model (dotted and dashed lines) is at Rhyp=15  km. The L19 models shown are for the United Kingdom (UK), Amatrice, Italy (Am), and northern Norway (NN). (c) Recovered YP21 ML values. Four events that had ML fixed to Mw in the inversion are highlighted by the red squares. The apparent decrease in ML around event 375 is likely due to a 2012 increase in the number of broadband stations available for picking amplitudes. (d) Recovered (empty triangles) and fixed (solid squares) YP21 Sj values. The 95% confidence intervals from 1000 bootstrap replications are shown as error bars, and the sum of YP21 Sj is in the top left.

Study area and velocity models. (a) Epicentral area of the 2016 Amatrice earthquake with 400 virtual stations (triangles) used for ground‐motion modeling with variable source scenarios. The black curves correspond to the Sibillini thrust separating different crustal regimes of the Norcia and Amatrice area. Colors distinguish velocity models used for stations in the Norcia (blue) and Amatrice areas (red). The black rectangles show the fault planes assumed in the scenario modeling, and focal mechanism plot shows the corresponding mechanism. A map of Italy with the study area depicted by a black rectangle is shown in the inset. (b) Velocity models were used to calculate Green’s functions for stations in the Norcia (blue) and Amatrice (red) area, with inset zooming in the uppermost 1 km.
