NATO SfP | Improvements in the Harmonized Seismic Hazard Maps for the Western Balkan Countries KICK-OFF MEETING & 1st PROJECT WORKSHOP SKOPJE 4-5 October 2012 S.Radovanović Unification of the magnitude scales and adding available earthquake metadata for the present earthquakes  General: The events makroseismic magnitude M m,M, M SK, up to 1970 are converted to M WU using the Scordilis relations ~50% of earthquakes occurred before 1971 ~1/3 of all Mwu are calculated based on Scordilis relations Aditional eforts to develop regional conversion relation for Mm,M, MSK, M WU is NECESSARY  Deadline end 2013 th

NATO SfP | Improvements in the Harmonized Seismic Hazard Maps for the Western Balkan Countries KICK-OFF MEETING & 1st PROJECT WORKSHOP SKOPJE 4-5 October 2012 S.Radovanović Providing a final earthquake catalogue compatible with international standards Basic postulates: 1.All data should have root reference as agreed in Format of the catalogue; 2.Relations adopted or developed for magnitude conversion should be documented (for the partners countries at list); 3.Earthquakes in the border zones of the countries should be attached to the national catalogue of the country with maximum makroseismic intensities 4.The sovereignty of states, in a manner that are internationally recognized, refers to the contents of catalogues and can not be subject to overruling
