Fig. 3From: Local and regional minimum 1D models for earthquake location and data quality assessment in complex tectonic regions: application to SwitzerlandFinal P-wave velocity models after 1-D inversion (left) and focal depth distribution (right). Models and focal depth distributions for different data sets are shown in different colors as indicated. Dashed horizontal lines mark layering in depth. For each model the final RMS travel time residual after 1-D inversion is givenBack to article page
