Assessment of Regional-Distance Location Calibration Using a Multiple-Event Location Algorithm

Velocity Models

The following two figures show travel time models used in this study. Only one was determined empirically [LLNL; Figure 1] from the travel-time picks also used for our location determinations.

Figures

Figure 1: Empirical travel time curves for GT0 events. Travel time model LLNL was determined from this data by linear regression.  

Figure 2: Depth versus p-wave and s-wave velocities for the travel time models used in this study.
