Abstract

A new function for -logAo has been deduced, and parameters determined using nonlinear regression analysis of data from the Victorian seismograph network. The formula for local magnitude supplied within the article has been adopted for the Victoria region. The values of - logAo closely follow the trend of Richters values at medium hypocentral distances. The features of Bakun and Joyners (1984) formula at close range, which were found to be applicable in Victoria, have been retained. The formula is applicable for distances from a few kilometers, and the maximum distance has been extended from 600 to 1000 km. The value of logS is closely related to the seismometer foundation, varying from about 0.0 at a bedrock site to more than 0.7 at soft sedimentary sites. The determination and application of site corrections is examined in detail.
