Within the module NA4: "A Distributed Archive of Historical Earthquake Data" (coordinator of the module Dr. M. Stucchi) of the EU-NERIES project, the "Macroseismic Database of the Southern Balkan area" was compiled on a joint effort of ITSAK (Ch. A. Papaioannou and A.S. Savvaidis), as module Partner, and the Geophysical Laboratory of the University of Thessaloniki (B.C. Papazachos, as principal researcher, and C.B. Papazachos) for the time period 1000-1999. The database is temporarily hosted by the INGV-MI.

The source of the data (macroseismic Intensity Data Points) are:

• for the historical (before 1900) earthquakes, the books of Papazachos and Papazachou (1989, 1997, 2003) and
• for the earthquakes of the instrumental era, the bulletins of the National Observatory, the books of Papazachos and Papazachou (1989, 1997, 2003) and individual studies.
