“…During the Middle Ages it retained its strategic importance and over the years it fell within the borders of both the Bulgarian and Byzantine Empires. In the 14th century it was conquered again and fell within the borders of the Ottoman Empire In 1878, Plovdiv was made the capital of the autonomous Ottoman region of Eastern Rumelia, in 1885 it became part of Bulgaria with the unification of that region and the Principality of Bulgaria [1].…”

The assessment of the effects of strong earthquakes is based on procedures for integrating the seismic hazard and the seismic vulnerability of the load-bearing structures of the building stock. The analyses are made for seismic excitation, determined by the analysis of seismic hazard - a deterministic earthquake scenario (expressed in macroseismic intensity). The scenario takes into account the effects of soil amplification, using the geotechnical information for the considered urban area. Based on the collected information about the building stock and the performed analysis, an assessment of the direct damages and destructions is obtained. The distribution of the buildings is graphically presented, respectively by number and by total built-up area, at different degrees of damage. Economic losses are calculated based on the results obtained for damage and destruction in three main groups of buildings. The main task of this study is to quantify the effects of strong earthquakes for the city of Plovdiv based on an accurate assessment of seismic hazard. This information will enable the municipal administration to make informed management decisions about planning of rescue equipment and people, hospital beds, shelter for the homeless people and financial resources to restore the damaged buildings.

Among natural disasters, earthquakes dominate with regard to their social and economic effects on human life and the urban environment. Appropriate risk reduction strategies can be developed only with a better understanding of seismic hazards as well as the population and building growth rates in the corresponding region. In the present study, deterministic and probabilistic earthquake (seismic) ground-motion scenarios are developed and presented for one of the most earthquake-prone cities in Bulgaria, the city of Plovdiv. We apply a method for integrating the spatial distribution of seismic hazards with human exposure to assess hazard impacts. Earthquake scenarios and social vulnerability metrics are combined in a geographic information system (GIS) to identify the spatial vulnerability of the exposed population to seismic risk and the locations for targeting mitigation actions in areas with high exposure and vulnerability levels. The results of our study show that most of the territory of the city is classified at the highest seismic hazard level: PGA 0.2. High and major levels were estimated for the population exposure index (PEI) for nearly 60% of the residential buildings in the city (inhabited by approximately 96% of the Plovdiv population). The spatial distribution of the results is available in GIS format and can be used in scientific and practical applications to reduce the risk and consequences of possible strong earthquakes in future.
