Becker, and Debi Kilb Dates: 2026-07 Description: This dataset contains receiver function maximum A1 amplitudes for stations within 5 km of major surface fault traces of the San Andreas Fault and other key faults in California. These A1 values are computed via the method detailed in Schulte-Pelkum and Mahan (2014) and Schulte-Pelkum et al. (2020). References Schulte-Pelkum, V., & Mahan, K. H. (2014).

Becker, and Debi Kilb Dates: 2026-07 Description: This dataset contains values for the anisotropy of the spatial distribution of microseismicity hypocenters. They were calculated as ζ (isotropy of hypocenters) by Ross et al., 2022. Here, we use the complement, 1-ζ. A value of 0 means that the distribution is isotropic, and 1 means fully anisotropic. The values were assigned to geographic locations as follows: We geolocated the boxes in Ross et al. 2022, Fig. 3 and Fig. 4 (see table boxes.csv) and assigned their reported values from their Table 1. We then resampled the values in each box along the fault surface traces in the SCEC CFM 7.0 (Plesch et al., 2023). References Ross, Z. E., Ben-Zion, Y., & Zaliapin, I. (2022).
