Abstract

AbstractAverage and standard deviations of hypocentral distances to selected isoseisms are presented for Albania and Yugoslavia. The results apply for the Medvedev‐Karnik‐Sponheuer (MKS) intensity, provided that all data are corrected to a unified MKS equivalent intensity as defined by Shebalin et al.19 The results should be useful in general macroseismic studies in these two countries, but are essential for the development of microzonation maps when the seismicity is described in terms of the locally available intensity catalogues.The observed attenuation of the intensities versus the hypocentral distance is similar to the attenuation of the Modified Mercalli Intensity (MMI) in the western United States of America. This finding should facilitate the use of other empirical scaling relations, developed in California, for various predictions of the characteristics of strong earthquake shaking in Albania and Yugoslavia.
