“…Global Positioning System (GPS) observations along the southern and central sections of the DSF reveal slip rates ranging between 3.8 and 6.0 mm/year (Al-Tarazi et al, 2011;Hamiel et al, 2016Hamiel et al, , 2018Le Beon et al, 2008;Masson et al, 2015;McClusky et al, 2003;Reilinger et al, 2006;Saleh & Backer, 2015;Sadeh et al, 2012;Wdowinski et al, 2004). Al-Tarazi et al (2011) used GPS measurements and calculated a locking depth of 9 ± 5 km and a slip rate of 4.7 ± 0.4 mm/year for the entire JVF.…”

Detailed field and geodetic observations of crustal deformation across the Jericho Fault section of the Dead Sea Fault are presented. New field observations reveal several slip episodes that rupture the surface, consist with strike slip and extensional deformation along a fault zone width of about 200 m. Using dense Global Positioning System measurements, we obtain the velocities of new stations across the fault. We find that this section is locked for strike‐slip motion with a locking depth of 16.6 ± 7.8 km and a slip rate of 4.8 ± 0.7 mm/year. The Global Positioning System measurements also indicate asymmetrical extension at shallow depths of the Jericho Fault section, between 0.3 and 3 km. Finally, our results suggest the vast majority of the sinistral slip along the Dead Sea Fault in southern Jorden Valley is accommodated by the Jericho Fault section.

“…South of Lebanon, geodetic measurements show ∼ 4-5 mm yr −1 sinistral slip rate (Masson et al, 2015;Hamiel et al, 2016Hamiel et al, , 2018a. Faulting in Lebanon is partitioned to a few branches (Fig.…”

“…At the northern section of the Jordan Valley long segment, section I is the least active part of the DST during the last ∼ 35 years. Shallow crust creep along the northern part of this segment at a rate of approximately half the total plate motion (Hamiel et al, 2016), and potential partitioning of the DST activity to the CTF (Sadeh et al, 2012;Hamiel et al, 2018b) might reduce the seismicity rate in section I (Fig. 6).…”

Abstract. We present a methodology for mapping faults that constitute a potential hazard to structures, with an emphasis on ground shake hazards and on surface rupture nearby critical facilities such as dams and nuclear power plants. The methodology categorises faults by hierarchic seismo-tectonic criteria, which are designed according to the degree of certainty for recent activity and the accessibility of the information within a given region. First, the instrumental seismicity is statistically processed to obtain the gridded seismicity of the earthquake density and the seismic moment density parameters. Their spatial distribution reveals the zones of the seismic sources, within the examined period. We combine these results with geodetic and pre-instrumental slip rates, historical earthquake data, geological maps and aerial photography to define and categorise faults that are likely to generate significant earthquakes (M≥6.0). Their mapping is fundamental for seismo-tectonic modelling and for probabilistic seismic hazard analyses (PSHAs). In addition, for surface rupture hazard, we create a database and a map of Quaternary capable faults by developing criteria according to the regional stratigraphy and the tectonic configuration. The relationship between seismicity, slip dynamics and fault activity through time is an intrinsic result of our analysis that allows revealing the dynamic of the deformation in the region. The presented methodology expands the ability to differentiate between subgroups for planning or maintenance of different constructions or for research aims, and it can be applied in other regions.
