The earthquake catalog of the National Observatory of Athens (NOA) since the
beginning of the Greek National Seismological Network development in 1964,
is compiled and analyzed in this study. The b-value and the spatial and
temporal variability of the magnitude of completeness of the catalog is
determined together with the times of significant seismicity rate changes.
It is well known that man made inhomogeneities and artifacts exist in
earthquake catalogs that are produced by changing seismological networks and
in this study the chronological order of periods of network expansion,
instrumental upgrades and practice and procedures changes at NOA are
reported. The earthquake catalog of NOA is the most detailed data set
available for the Greek area and the results of this study may be employed
for the selection of trustworthy parts of the data in earthquake prediction
research. |
