The objective of this research is a differentiated scenario-based seismic hazard assessment of the territories of oil and gas fields on Absheron peninsula through analysis of distribution of peak ground acceleration (PGA) and calculation of site amplification factor. Azerbaijan's hydrocarbon deposits are mainly located in the South Caspian oil and gas basin, as well as on the territory of the Absheron peninsula, where more than 80 oil and gas fields are located. By using probabilistic seismic hazard analysis and clustering of seismic events that occurred in the southern part of the Caspian Sea in 2000, the magnitude of the Caspian Sea (Mw 6.1; 6.2, 25.11.2000) seismic event for the current study as a scenario earthquake was assumed to be 6.3. To plot models of the PGA distribution in the study area, the values of the amplification factor of the site effect were calculated based on the analysis of boring data and lithological materials. Calculated values of PGA according to the macroseismic data of the Caspian earthquake vary within 100-380 gal in the field of  Balakhany-Sabunchi-Ramany oil fields, which is one of the first oil fields of  the Absheron  pe­ninsula and also is the territory of research.
