A new evaluation of seismic hazard for the northwestern part of Saudi Arabia

Potential Seismogenic Source Model for the Red Sea and Coastal areas of Saudi Arabia

“…Seismogenic source zones can be defined on various criteria. The basic division is done on the basis of present-day geological and tectonic setting, historical and recent seismicity, the location of known faults and heat flow measurements for crustal studies (Musson 2009, Burkhard and Grünthal, 2009, Pailoplee et al, 2010, Ares, 2010, Al-Arifi et al, 2013.…”

“…The northwestern regions of Saudi Arabia were assessed by Al Arifi et al (2013). The author divided study zone into twelve seismogenic source zones on the basis of earthquakes, spatial distribution and tectonic setting of the study area and vicinity.…”

Development and Validation of Software CRISIS to Perform Probabilistic Seismic Hazard Assessment with Emphasis on the Recent CRISIS2015

“…Figure 9 shows the screen of CRISIS2015 [48,49] where the geometry of the seismic sources is assigned. This image correspond to a seismic source defined to assess the seismic hazard of Barcelona, Spain [6]. In this screen of CRISIS2015 [48,49] is also available the option of see the seismic source in different planes as in Figure 8.…”

Preliminary probabilistic seismic hazard assessment for the Kingdom of Saudi Arabia based on combined areal source model: Monte Carlo approach and sensitivity analyses

“…At the same time, we avoid models that provide superfluous detailing for the zones [36]. The composed model covering almost the whole territory of KSA and neighboring regions has been compiled on the basis of the models described in the following studies, namely: Pascucci et al [59], Deif et al [37], Mohindra et al [53], and Al-Arifi et al [7]. These basic seismic source (BSS) models are presented in Fig.…”

“…Al Haddad et al [8,9] used these ground-motion models to estimate PGA for 10% of being exceeded in 50 years and suggested seismic zonation map for KSA to be used as a basis for seismic design. Seismic hazard for particular areas in KSA and the neighboring countries was analyzed by Deif et al [36] (Sinai Peninsula and Gulf of Aqaba area, PGA and spectral acceleration for rock sites, single GMPE); Deif et al [37] (area of construction of Makkah-Madinah high-speed rail, PGA and spectral acceleration for rock sites, consideration of several GMPEs in logic tree scheme); Osman [56] GMPE); Al-Malki and Al-Amri [11] (southwestern part of KSA, PGA and spectral acceleration were estimated for bedrock and sedimentary rock sites on the basis of semi-theoretical ground-motion models obtained by stochastic simulation); Al-Arifi et al [7] (northwestern part of KSA, PGA and spectral acceleration for rock sites, single GMPE).…”
