In this paper we are presented brief overview of the project  "Evaluation of seismic hazard for Georgia and  seismic risk for city Mtskheta with modern aproaches". Seismic hazard and risk assessment is very importance in Southern Caucasus (SC) and particularly in Georgia. The goal of society is to create urban environment that is protected from destructive earthquakes and minimize the expected losses. However, complete elimination of expected losses is unreal. One of the reasons for it is deficiency of knowledge about real seismic hazard and vulnerability of urban areas and infrastructure. In this regard, the general purpose of this project was to provide a reliable seismic hazard assessment at the national level and risk assessment for strategically important objects (cities, critical facility, lifelines, cultural heritage and others) of Georgia. In our case Historic city Mtskheta was chosen as strategic objects. Historic city Mtskheta is located in eastern Georgia, and is the administrative centre of the region of Mtskheta-Tianeti and Mtskheta Municipality. Mtskheta is a city museum and in 1994 was listed as a UNESCO World Heritage Site. Mtskheta is characterized by increasing urbanization, population density and infrastructure. Also taking into account the current reality of high vulnerability, the results of this project allowed us to evaluate recommendations for a new strategy of urban planning of the city, by proposing specific mitigation actions in district with high seismic risk, as well as adequate protection of infrastructures in case of earthquake.
