Dataset for "Fault Network Geometry Modulates Earthquake Source Spectra Across Scales"

The datasets provided here are from the paper “Lee, J., Tsai, V. C., Trugman, D. T., Hirth, G., & Chatterjee, A. (2025). Fault network geometry modulates earthquake source spectra across scales. Geophysical Research Letters, 52, e2025GL115592. https://doi.org/10.1029/2025GL115592". They include earthquake stress-drop and fault misalignment (Rm) measurements from Southern California (Shearer et al., 2022), Japan (Oth, 2013) and Italy (Kemna et al., 2021). The SCARDEC datasets provide estimated corner frequencies, moment-rate roughness (Radiated Energy Enhancement Factor; REEF) and mean Kagan angles computed within proximity of each event (count#).
