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.
