Abstract
The March 2, 1987 Edgecumbe, New Zealand earthquake had a magnitude (M1) 6.3 and seismic moment 7.0*1018 N*m. Later aftershocks, from March 15 to 27, were monitored with 10 portable smoked paper recorders operated by the United States Geological Survey, and by seven digital event recorders from the University of Nevada, Reno. Two magnitude scales for these aftershocks were established by calibration of amplitudes and coda durations with seismic moments determined from digital records for 18 events. Most events analyzed have magnitudes between 1.0 and 2.8.
