Table S1. Well-constrained earthquake relocations from bootstrap implementation of HYPODD using cross-correlation phase arrivals.
Well-constrained relocation results using differential travel-time cross-correlated phase arrivals from 5000 bootstrap iterations HYPODD (Waldhauser and Ellsworth, 2000). The cluster centroid is located at 34.55397, -97.42324, and 2.527 km depth with the variations of each earthquakes location for iterations of the bootstrap implementation of HYPODD. The average variations for all earthquakes are 20.1 m, 58.3 m, and 550.0 m for longitude, latitude and depth respectively. Mean NCCP is the average number of cross-correlated P-arrivals, and Mean NCCS is the average number of cross-correlated S-arrivals. Mean RMS is the average root mean squared residuals reported by each iteration of HYPODD. The event identification number is included for reference with events used as a template for phase correlations indicated in bold.
Table S2. Poorly-constrained earthquake relocations from bootstrap implementation of HYPODD using cross-correlation phase arrivals.
Poorly constrained relocation results using differential travel-time cross-correlated phase arrivals from 5000 bootstrap iterations HYPODD (Waldhauser and Ellsworth, 2000). Mean NCCP is the average number of cross-correlated P-arrivals, and Mean NCCS is the average number of cross-correlated S-arrivals. Mean RMS is the average root mean squared residuals reported by each iteration of HYPODD. The event identification number is included for reference.
