Although body-wave magnitude mb (as well as surface-wave magnitude Ms) is rapidly being supplanted by moment magnitude MW as the magnitude of record for moderate to large earthquakes, the first, automatically determined teleseismic estimate of earthquake size is still mb. While efforts are underway to implement various automated estimates of MW, these have not, to date, proven entirely successful, nor are they rapid enough to satisfy the rapid reporting requirements of the National Earthquake Information Center (NEIC). For example, estimates of MWP, computed by integrating the broadband P-wave displacement...
