Catalogs and Data
From May 1997 through July 2013, the USGS/NEIC produced monthly catalogs of large routine explosions and planned roof collapses at mines and quarries in the United States. Events in these catalogs were not included in the regular USGS/NEIC catalog of seismic events. Beginning in August 2013, routine mining-associated events have been listed in the same on-line catalog as earthquakes, rather than in separate catalogs. The current on-line catalog also lists, for some regions of the U.S., mining events that were located by regional networks prior to August 2013 and that were not originally listed in catalogs produced by the USGS/NEIC.
Phase arrival times for months from May 1997 to July 2013 are available in the MCHEDR format, and arrival-times for months from October 1999 through July 2013 are available in the ISF format.
- Data in ISF Format (1997-July 2013) - file names are isfexpYYYYMM.dat.Z

Unusually large mining-induced events that are listed in regular earthquake catalogs of the USGS/NEIC are not listed in the catalogs of "Routine Mining Seismicity in the United States."
Goal and Scope of the Catalog
explains the seismological context in which the routine explosions and collapses are recorded and their locations calculated: we discuss uncertainties in the magnitudes of the cataloged seismic events and variations in the completeness of the catalog.
Evidence Used in Identifying Routine Mining Seismicity
explains the evidence that is used to identify routine explosions or planned collapses, and we note that in some areas a few natural earthquakes or unplanned rockbursts may be listed in the catalogs of routine mining seismicity.
Explanation of Catalog Listings
explains the parameters listed in "Routine Mining Seismicity in the United States".
State-by-State List of Mining Regions
summarizes what we know about mining districts from which we have recorded explosions, planned collapses, and rockbursts.
Funds for the development of this catalog were provided by the Verification and Compliance Division of the United States Arms Control and Disarmament Agency, the Defense Threat Reduction Agency of the U.S. Department of Defense, and the U.S. Department of State.
