For origin times after September 30, 2002, USGS computations of hypocenters and magnitudes for routine mining events are listed in this publication only for exceptionally large events and for events that are also listed in the Reviewed Event Event Bulletins (REB) of the International Data Center of the United Nations' Comprehensive Nuclear-Test-Ban Treaty Organization.
