AB: Questions of assessment of earthquake economical losses on urban territories of Uzbekistan, taking into account damage forming factors, which are increqasing or reducing economical losses were discussed in the paper. Buildings and facilities vulnerability factors were classified. From total value (equal to 50) were selected most important ones. Factors ranging by level of impact and weight function in loss assessment were ranged. One group of damage forming factors includs seismic hazard assessment, design, construction and maintenance of building and facilities. Other one is formed by city planning characteristics and includes : density of constructions and population, area of soft soils, existence of liquefaction susceptible soils and etc. To all these factors has been given weight functions and interval values by groups. Methodical recomendations for loss asessment taking into account above mentioned factors were developed. It gives possibility to carry out preventive measures for protection of vulnerable territories, to differentiate cost assessment of each region in relation with territory peculiarity and damage value. Using developed method we have ranged cities by risk level. It has allowed to establish ratings of the general vulnerability of urban territories of cities and on their basis to make optimum decisions, oriented to loss mitigation and increase of safety of population. Besides the technique can be used by insurance companies for estimated zoning of territory, development of effective utilization schema of land resources, rational town-planning, an economic estimation of used territory for supply with information of the various works connected to an estimation of seismic hazard. Further improvement of technique of establishment of rating of cities by level of damage from earthquakes will allow to increase quality of construction, rationality of accommodation of buildings, will be an economic stimulator for increasing of seismic resistance of building.
