The source model combines well-known identified faults (i.e North Anatolian Fault, Dead Sea Fault, Chaman Fault) with seismogenic segments or sections compiled within the region. The total number of database entry: 3397 fault segments; total Km: 91551km, However, not all the compiled faults were used to derive the fault source model. From the entire dataset the selection was based on the following criteria:
- Active in Quaternary (1 million years) with a slip-rates of about 0.1mm/year
- Late Quaternary active faults (observed or assigned fault movement during the last 50000 to 130 000years)
- Geological feature (section, segment or faults) have a slip rate at least 0.10mm/year corresponding to 1m in Holocene (~10 000years).
- Maximum magnitude equal to 6.20
The faults were ranked based on the information availability, accuracy and confidence. Top ranked faults were used for hazard assessment. The fault source map presents the selected faults as a function of their slip-rate as well as their 3D geometry. Each fault source is defined as a composite source; they are fully parameterized, including parameters of geometry, slip rate, moment rate etc. together with uncertainties, defined as maximum and minimum values. Activity on fault sources is computed by converting the geological slip rates into seismicity.
