Table 3: Seismicity parameters (average depths, annual rate of earthquakes above Mw 4.0, \(b\)-value, maximum observed/recorded and maximum expected magnitudes) and stress regime for the model by [PERSON] et al. [2]. The third alternative seismic source model is the one developed by [PERSON] et al. [65] that used before to assess the seismic hazard for the Arabian Peninsula. Among the 57 area sources defined by [PERSON] et al. [65] for the whole Arabian Peninsula, only twenty-two area sources (Figure 2c) have been considered, which can influence the seismic hazard in the studied region. The considered seismic sources, as labelled from the authors, are the following: from 1 to 18, and from 54 to 57 (see Figure 2c). Labelled sources \(Z\)-1 (Makran East), \(Z\)-2 (Makran Interplate), \(Z\)-3 (Makran West), \(Z\)-4 (Jaz-Murian), \(Z\)-5 (Zendan Fault), \(Z\)-6 (Jiroft Fault), \(Z\)-7 (Ali Abad), and \(Z\)-8 (Gowk Fault) are covering the seismicity along the Makran subduction zone. However, sources labelled as Z-9 (Arabian Gulf), \(Z\)-10 (Zagros Foredeep), \(Z\)-11 (Zagros Simple Fold), \(Z\)-12 (High Zagros), \(Z\)-13 (Sabz-Pushan Fault), \(Z\)-14 (Karebas Fault), \(Z\)-15 (Kazern Fault), \(Z\)-16 (Borazjan Fault), \(Z\)-17 (Dezful Embayment), and \(Z\)-18 (Mesopotamia) cover the seismicity along the Zagros region. Finally, an additional four sources (Z-54, Z-55, Z-56, and Z-57) were included by the authors to cover the seismicity along the Owen, Murry Ridge, Oman Mountains, and the Arabian Cratonic region, respectively. This last source (Z-57) is acting as a background zone in this assessment in particular, i.e., an area source without any identifiable fault sources, modeling the diffuse seismicity.
