Description
Summary:The assessment of losses from strong earthquakes and the reduction in earthquake consequences are of great importance in maintaining seismic safety. Special attention is given to evaluating the magnitude of economic losses caused by earthquakes, particularly the assessment of different levels of seismic risk, in order to protect the population and territories located in seismically active areas. To ensure sustainable development of countries, it is essential to estimate the economic losses that will occur in regions due to strong earthquakes and forecast them within the specified return periods at given probabilities. Measures can then be implemented to mitigate the consequences of earthquakes. For the basis of seismic risk assessment, maps of seismic intensity increment and an improved map of seismic hazard have been developed, taking into account the engineering-geological conditions of the territory of Uzbekistan and the seismic characteristics of soils. For seismic risk map development, databases were created based on GIS platforms, allowing us to systematize and evaluate the regional distribution of information on seismic hazards, the number of buildings and construction types, the coefficient of the seismic vulnerability of buildings, the cadastral value of buildings, etc.
