The database contains uniformly processed ground motion intensity measurements (peak horizontal ground motions and 5-percent-damped pseudospectral accelerations for oscillator periods 0.1–10 s). The earthquake event set includes more than 3,800 M≥3 earthquakes in Oklahoma and Kansas from January 2009 to December 2016. Ground motion time series were collected out to 500 km. We also relocated the majority of the earthquake hypocenters using a multiple-event relocation algorithm to produce a set of near-uniformly processed hypocentral locations. Details about data processing are reported in the accompanying article. First posted - October 11, 2017 Revised - December 18, 2017, ver. 1.1

The Fairview cluster is based on a sequence of small earthquakes near Fairview, Oklahoma, U.S.A., that began in 2014. After magnitude 5.1 and 5.2 events in early 2016 a temporary network was installed, which recorded continuing seismicity through the rest of 2016 and enabled very precise calibration of the cluster. Number of events: 55 Calibration type: direct calibration using data to 0.5 degrees; hypocentroid calibration level = 0.3 km Epicentral calibration range: 0 - 1 km Date range: 20140902 - 20170115 Latitude range: 36.247 - 36.547 Longitude range: -99.033 - -98.059 Depth range: 5.0 - 12.1 Magnitude range: 2.5 - 5.1
This ScienceBase entry contains three seismic catalogs supporting and described by the manuscript - Koper, K. D., Pankow, K. L., Pechmann, J. C., Hale, J. M., Burlacu, R., Yeck, W. L., et al (2018). Afterslip Enhanced Aftershock Activity During the 2017 Earthquake Sequence Near Sulphur Peak, Idaho. Geophysical Research Letters, 45. https://doi.org/10.1029/2018GL078196. These are included in three separate catalog files: the University of Utah Seismograph Stations (UUSS) absolute locations, the MLOC relocations, and the GrowClust relocations. The absolute USGS locations are available from the USGS ComCat (https://earthquake.usgs.gov/data/comcat/).
These data were used to train the Machine Learning models supporting the USGS software release "NEIC Machine Learning Applications Software" (https://doi.org/10.5066/P9ICQPUR), and its companion publication in Seismological Research Letters "Leveraging Deep Learning in Global 24/7 Real-Time Earthquake Monitoring at the National Earthquake Information Center" (https://doi.org/XXXXX). These data are formatted as python numpy arrays and readable by the python code used to generate deep-learning models that classify waveform phases, refine automatic pick timings, and estimate source distances. The cataloged picks and associated metadata were obtained from the USGS PDE catalog (https://earthquake.usgs.gov/data/pde.php)....
The dataset contains the catalog of 5446 events and arrival times resulting from subspace detection processing and relocation in the for the 2011 Prague, Oklahoma, aftershock sequence. Lines beginning with "E" contain event information in the following order: event ID, origin year, origin month, origin day, origin hour, origin minute, origin second, latitude, longitude, depth, and magnitude. Lines beginning with "P" contain phase information in the following order: event ID, network, station, phase, phase arrival year, phase arrival month, phase arrival day, phase arrival hour, phase arrival minute, phase arrival second.
This data release contains seismic and geodetic observations as well as finite-fault inversion results for the February 6, 2023, Mw7.8 Pazarcık earthquake. The dataset includes broadband teleseismic data, regional strong-motion accelerometer data, high-rate Global Navigation Satellite System (GNSS) data, static GNSS offset estimates, Synthetic Aperture Radar azimuth and range displacements, 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://github.com/slipinversion/WASP). These data follow the standard formats used by the National Earthquake Information Center (NEIC) for all finite-fault model products....

This dataset contains the supplemental information for the article "Oklahoma experiences largest earthquake during ongoing regional wastewater injection hazard mitigation efforts" published in Geophysical Research Letters (Yeck and others, 2017). Included is a table of relocated earthquake hypocenters and the velocity model used in the event relocations. These locations form the basis of the analysis presented in the article.

We used matched filter detection and multiple-event relocation techniques to characterize the spatiotemporal evolution of the sequence. Our analysis is from the 14 closest seismic stations to the earthquake sequence, which included seven permanent stations from the Montana Regional Seismic Network, one permanent station from the ANSS backbone network and three temporary seismic stations deployed by the USGS within four days after the mainshock. A catalog of 685 well-located earthquakes larger than M 1 occurring Between 5 July and 15 October 2017 were relocated using a hypocentroid decomposition (HD) multiple-event relocation approach. The resulting dataset had an average epicentral and depth uncertainties (90% confidence)...

This directory includes the SAR sub-pixel offsets fields at the full processed spatial resolution (~30 m per pixel) along with line-of-sight (LOS) vector files that span both the M7.8 Pazarcık earthquake (us6000jllz) and the M7.5 Elbistan earthquake (us6000jlqa), as well as all other aftershocks that occurred within the spanned date ranges. The included results were derived from Sentinel-1A image pairs acquired from three different relative orbit paths (path 14, path 21, and path 116). These data sets were processed using the standard workflows of the InSAR Scientific Computing Environment (ISCE) SAR processing package (Rosen et al. 2012, Agram et al. 2013), preliminary satellite orbits, and the 30 m Shuttle Radar...
