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 2016 M5.8 Pawnee, Oklahoma earthquake is the largest earthquake to have been induced by wastewater disposal. We infer the coseismic slip history from analysis of apparent source time functions and inversion of regional and teleseismic P-waveforms, using aftershocks as empirical Green’s functions. The earthquake nucleated on the shallow part of the fault, initially rupturing towards the surface, followed shortly thereafter by slip deeper on the fault. Deeper slip occurred below the aftershocks and at greater depths than most induced seismicity in the region, suggesting that small- to moderate-sized earthquakes may not occur on deeper parts of faults in Oklahoma because they are further from failure than shallower...
The National Seismic Hazard Model (NSHM) and Seismic Design Maps are a suite of products primarily aimed at improving earthquake-resilient construction in the United States by providing information about potential ground shaking caused by earthquakes. The NSHM is updated every six years to provide the basis for the Seismic Design Maps used in building codes.

The dataset comprises information about the magnitudes, distances and periods of ground motion measurements from an analysis of earthquake ground motions from induced events in Oklahoma and Kansas. The data set also includes ground motion residuals from comparing earthquake ground shaking with commonly used models for predicting ground motions in the U.S.

Fragile geologic features (FGFs) are elements of the landscape that are vulnerable to destruction during sufficiently strong earthquake ground shaking. As result, the observation of extant FGFs on the landscape may constrain the maximum intensity of past earthquake shaking. McPhillips and Scharer (2022, Survey of fragile geologic features and their quasi-static earthquake ground motion constraints, southern Oregon, Bulletin of the Seismological Society of America 112 (1)) demonstrated the potential to derive useful ground motion constraints from rock towers, such as sea stacks, in the Pacific Northwest region of the United States. The data set presented here extends the survey of McPhillips and Scharer (2022) along...
