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 latitude north). Note, hazard in the western U.S. (-125 to -115 longitude west) is taken from gridded hazard curve results of the 2014 National Seismic Hazard Model for the Conterminous U.S. (https://doi.org/10.5066/P9P77LGZ). Development of the 2016 One-Year Seismic Hazard Forecast for the Central and Eastern U.S. from Induced and Natural Earthquakes is documented in the USGS Open-File Report 2016-1035 (https://doi.org/10.3133/ofr20161035).
This dataset is considered a legacy dataset. The original dataset was uploaded to the USGS website at the time of publication of the seismic hazard model (2016) but was later moved over the the USGS ScienceBase Catalog (2019). The original dataset was assumed to be complete and accurate, but may contain inconsistencies when compared to more recent, actively maintained datasets.
