Comment on "Empirical determination of depth-distance corrections for mb and Mw from global seismograph network stations"

Abstract

This paper looks at the bases for the cited depthdistance corrections by Guust Nolet, Steve Krueger, and Robert M. Clouser (Paper 98GL01094, GRL, Vol. 25, No. 9, pp. 1451-1454, May 1, 1998), the historic curves of Gutenberg and Richter, and those given by Veith and Clawson (1972). It discusses the some of the problems associated with the establishment of such curves and suggests modes of strengthening both the current work and potential future work.
