Summary

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 [...]

Purpose

These data are a compilation of several earthquake source catalogs that are reformatted to a standardized record that lists basic information about each earthquake. The catalog has been declustered and lists natural and induced earthquakes without duplicates, restricted to magnitudes greater than or equal to 2.5.
