Online_Linkage: http://quake.geo.berkeley.edu/anss/catalog-search.html Process_Step: Process_Description: We utilize 35 years (1975-2009) of recorded earthquakes from the ANSS catalog, filtered to be consistent with the 25 years (1984-2008) of relocated NCSN catalog earthquakes. Specifically, we retained earthquakes recorded at a minimum of 6 stations, with locations having a maximum RMS of 0.5 s, between depths of 0-150 km, and ranging in magnitude from 0-7+. In addition, we eliminated events whose formal vertical (depth) error was 10 km or greater. Similar station, RMS, and vertical error data were not available for the 25 years (1985-2009) of CNSN data utilized in this study Process_Step: Process_Description: Metadata imported.
