This data release pertains to the December 20, 2022, Mw6.4 Ferndale, California, earthquake and complements the following publication: Shelly, D. R. et al. (2023) Subduction intraslab-interface fault interactions in the 2022 Mw 6.4 Ferndale, California, earthquake sequence. [insert publication info when available!]. This page contains: (1) Files pertaining to earthquake relocations, (2) Files pertaining to postseismic GNSS analysis, and (3) Input data and model results from the coseismic finite-fault inversions. See attached ReadMe.txt for details. The dataset includes broadband teleseismic data, regional strong-motion accelerometer data, high-rate Global Navigation Satellite System (GNSS) data, static GNSS offset estimates, and a centroid moment tensor solution in the formats necessary for input to the Wavelet and simulated Annealing SliP (WASP) finite fault inversion code (https://code.usgs.gov/ghsc/neic/algorithms/neic-finitefault). The broadband seismic data in this data release are from globally distributed seismometers from networks G (https://doi.org/10.18715/GEOSCOPE.G), GE (https://doi.org/10.14470/TR560404), GR (https://doi.org/10.25928/mbx6-hr74), GT (https://doi.org/10.7914/SN/GT), II (https://doi.org/10.7914/SN/II), IU (https://doi.org/10.7914/SN/IU), and US (https://doi.org/10.7914/SN/US). Strong-motion accelerometer data are from networks BK (https://doi.org/10.7932/BDSN), NC (https://doi.org/10.7914/SN/NC), and NP (https://doi.org/10.7914/SN/NP). Global Navigation Satellite System (GNSS) data are from the Network of the Americas, operated by the EarthScope Consortium (https://www.unavco.org/nota/). Please see Goldberg et al.
