Abstract

We have reappraised locations and surface wave magnitudes of earthquakes this century in the Eastern Mediterranean and the Middle East, between 10 and 44N and 18 and 70E. The results are presented in an improved parametric catalogue of shallow earthquakes (h <= 40 km), large enough (MS >= 6.0) to be of interest in seismotectonics and earthquake engineering. A considerable number of early events of 6 <= MS < 7.2, not included in other catalogues, have been identified and their magnitudes assessed. We find that ISS/ISC locations are systematically shifted by 10-30 km to the north or northeast of their macroseismic epicentres. Also we derived a regional average relationship between log M0 and MS. We show that the correlation of magnitude with epicentral intensity is very weak, as is expected, and a source of error in frequency relations.
