Abstract

Measurements of maximum trace amplitudes from 181 short- period vertical seismograms recorded at hypocentral distances of 3-1500 km from 36 earthquakes in the magnitude range 0.8 - 4.3 were used to derive a new preliminary ML scale for southeastern Australia ML = log A + (1.34±0.09)log(R/100) + (0.00055±0.00012)(R-100) + 3.13 + S where ML is local magnitude, A (mm) is equivalent Wood-Anderson trace amplitude not corrected for the measurement having been made on a vertical component, R (km) the hypocentral distance and S the station correction.
