Regional and Teleseismic Observations for Finite-Fault Product

Metadata Updated: October 29, 2025

This data release complements the following publication: Goldberg, D. E., P. Koch, D. Melgar, S. Riquelme, and W. L. Yeck (2022). Beyond the Teleseism: Introducing Regional Seismic and Geodetic Data into Routine USGS Finite-Fault Modeling, Seismol. Res. Lett. XX, 1–16, doi: 10.1785/0220220047. Rapid finite-fault models are published by the US Geological Survey (USGS) National Earthquake Information Center (NEIC) routinely following large (M7+) earthquakes. Finite-fault models estimate the spatiotemporal evolution of heterogeneous slip across a fault. The type of data used as input to a finite-fault inversion affects the overall resolution of the model and the slip pattern itself. In the associated manuscript, we demonstrate the performance of joint regional and teleseismic finite-fault models in comparison to teleseismic-only models. This data release pertains to the July 29, 2021, Mw8.2 Chignik, Alaska, United States, the August 14, 2021, Mw7.2 Nippes, Haiti, the July 8, 2021, Mw6.0 Antelope Valley, California, United States, and the September 16, 2015, Mw8.3 Illapel, Chile, earthquakes. Data is provided in the input formats required for the Wavelet and simulated Annealing SliP (WASP) finite-fault inversion code (https://github.com/slipinversion/WASP). The release inludes preferred solutions for teleseismic-only inversions as well as preferred solutions for joint teleseismic and regional inversions. The broadband seismic data in this data release is from globally distributed seismometers from networks AI, AK, AT, AV, BK, C, C1, CC, CH, CI, CN, CX, CZ, DK, G, GE, GR, GS, GT, II, IM, IU, IV, IW, KO, LX, MN, MX, OE, PL, PM, RO, SC, SJ, SS, US, UW, and WM. Strong-motion accelerometer data is from networks AK, AY, C1, CC, NC, and NN. Global Navigation Satellite Systems (GNSS) data is from the Network of the Americas, the Mobile Array of GPS for Nevada Transtension network, and the Centro Sismológica Nacional GNSS network. Sentinel-1 Interferometric Synthetic Aperture Radar observations are from the European Space Agency.
