The magnitude-intensity-focal depth relation for the earthquakes in the wider Dinara region

Abstract

The regression coefficient in the M-I_o-log h relation were estimated on the basis of local magnitudes (M), epicentral intensities (I_o) and focal depths (h) of 50 earthquakes which occurred in the wider region of Dinara mountain, Yugoslavia. The relation is

                                    -M/3.18 + (log h)/1.72 + I_o/3.63 -1 = 0.

Since the three-axes regression was utilized the resulting expression is valid for estimation of any of the variants on the basis of the observations of other two.
