Keywords: Gyumri city (Leninakan city), soil model, earthquake, earthquake scenario, seismic hazard and risk assessment, vulnerability, losses and damage
Аnnotation: The degree of damage and losses caused by the Spitak earthquake (1988) and its magnitude ( M = 6.9) were not commensurate. It is very important to know what the real level of seismic risk in Gyumri city (former Leninakan city) is now, and what losses the city could expect if a similar or stronger earthquake occurred nowadays. To answers this question the scenarios of the most probable earthquakes for Gyumri city has been developed based on a comprehensive assessment of seismic hazard. Based on the analysis of real data on losses and damages caused by Spitak earthquake, the correct values of the required parameters used in ELER software for assessing the vulnerability of buildings and structures of the region have been selected. For the three selected earthquake scenarios of the Gyumri city the expected losses and varying degrees of damages have been calculated using ELER software.
