Abstract

The regression coefficient in the M-Io-log h relation were estimated on the basis of local magnitudes (M), epicentral intensities (Io) 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 + Io/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.
