Researchers distinguish waves from mine collapses from other seismic activities

Researchers have devised a technology that can distinguish mine collapses from other seismic activity. Using the large seismic disturbance associated with the Crandall Canyon mine collapse last August, Lawrence Livermore National Laboratory scientists and colleagues from the Berkeley Seismological Laboratory at UC Berkeley applied a method developed to detect underground nuclear weapons tests to quickly examine the seismic recordings of the event and determine whether that source was most likely from a collapse.
