Three-dimensional grid of properties used to analyze induced seismicity recorded from 1991 to 2012 at Paradox Valley, Colorado
Large numerical grid used for finite element and finite volume analysis of induced seismicity in Paradox Basin. The grid construction used the boundaries of three sub-horizontal surfaces; the topography, and the top and bottom of the production formation is determined from drilling and seismic reflection profiling, yielding the surface topography and thickness variations in these data throughout the domain. The cell dimensions in the north and east directions are 200 m and the horizontal gridlines are oriented north-south and east-west. There are 245 elements in the east west direction, 241 elements in the north south direction, and 31 elements in the vertical, extending from the surface to 15 km depth. The grid...
Airborne magnetic surveys were conducted in Oklahoma from August 11th, 2017-October 28th, 2017, by Goldak Airborne Surveys. Here we present downloadable flight line data from those surveys in comma-separated values (csv format). Three areas were flown along a draped surface with a nominal survey height above ground of 120 meters. The flight line spacing for these areas was 200 to 400 m for Area 123, in southwestern Oklahoma; 1000 m for Area 4, in northwestern Oklahoma, and 800 m for Area 5, in north-central Oklahoma. For each area control lines were flown at ten times the traverse line spacing. The surveys were flown to map subsurface geologic variations including ancient magmatic bodies, faults, and other geologic...

Data Release for the 2016 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes
Seismicity catalogs, gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2016 One-Year Seismic Hazard Forecast for the Central and Eastern U.S. from Induced and Natural Earthquakes. Probabilistic seismic hazard data and maps of the conterminous U.S. for peak ground acceleration (PGA) and 0.2 and 1.0 second spectral acceleration at a probability level of 1 percent in 1 year (annual probability of 0.0101), assuming firm rock soil conditions at 760 m/s, are available. Hazard was calculated on a 0.05 degree by 0.05 degree grid, defined by a bounding box encompassing the central and eastern U.S. (-115 to -65 degrees longitude west, 24.6 to 50 degrees...
