The paper presents probabilistic seismic hazard analysis used for constructing the actual seismic hazard map of Romania. The new edition of the code for design of earthquake-resistant buildings and structures in Romania P100 was just issued in 2006 and follows the format and contents of Eurocode 8. Based on the available data obtained from more than 400 boreholes and using the GIS techniques, significant soil parameters were mapped for the territory of city of Bucharest and permit seismic microzonation of Bucharest to be used as a tool for urban planning and earthquake risk reduction. The paper also explains the synergy between national programs and international projects as: JICA Project “Seismic Risk Reduction for Building and Structures in Romania”, World Bank Hazard Risk Mitigation and Emergency Preparedness Project in Romania (2004-2009) - Component B: Earthquake Risk Reduction, RISK-UE Project “An advanced approach to earthquake risk scenarios with application to 7 European towns (2001- 2004) and European Project PROHITECH “Earthquake Protection of Historical Buildings by Reversible Mixed Technologies” (2007-2009).
