“…Based on seismic observatory data and historical practice, Felzer (2007) and Frankel and Mueller (2008) provided estimates of magnitude uncertainties and rounding errors for earthquakes in the CGS/WGCEP catalog, and we extend the guidelines given in her work to estimate magnitude uncertainty and rounding errors for earthquakes in the rest of the WNA catalog. As rough first steps to account for these effects, we assume standard errors of about 0.1 magnitude unit for earthquakes in 1972-2006, 0.2 for 1932-1971, and 0.3 for 1850-1931.…”
