Catalog of natural and induced earthquakes without duplicates
The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (CEUS), and some have caused damage. In response, the USGS is now also making short-term forecasts that account for the hazard from these induced earthquakes. A uniform earthquake catalog is assembled by combining and winnowing pre-existing source catalogs. Seismicity statistics are analyzed to develop recurrence models, accounting for catalog completeness. In the USGS hazard modeling methodology, earthquakes are counted on a map grid, recurrence models are applied to estimate the rates of future earthquakes in each grid cell, and these rates are combined with maximum-magnitude models and ground-motion models to compute the hazard. The USGS published a forecast for the years 2016, 2017, and 2018. This data set is the catalog of natural and induced earthquakes without duplicates. Duplicate events have been removed based on a hierarchy of the source catalogs. Explosions and mining related events have been deleted. Within the catalog, a field within each event's record signifies whether the event is considered to be induced or natural. Another field also signifies if the event is considered to be a dependent or independent event.
