“…Freund et al, ; Garfunkel, ). GPS measurements along the fault yield modern slip rate estimates of ~4–4.9 mm/yr (Le Beon et al, ; Masson et al, ). This value is intermediate in the estimated range of slip rates (1.5–8.5 mm/yr) calculated by various workers using geological and archeological evidence of offset (reviewed in Marco & Klinger, ).…”

Integrated Paleoseismic Chronology of the Last Glacial Lake Lisan: From Lake Margin Seismites to Deep‐Lake Mass Transport Deposits

Seismically disturbed sedimentary sequences (seismites) in the last glacial (70–14 ka) Lisan Formation are exposed in the marginal terraces of the Dead Sea and recovered from sedimentary core drilled by the International Continental Scientific Drilling Programs at the depocenter of the lake at water depth of 300 m. The core reveals various types of centimeter‐ to meter‐scale disturbed lake sediments: turbidites, homogenites, slumps, and other deformations, interspersed with undisturbed lamination. The transported sediments comprise a main source of the thickness tripling of the Lisan Formation at the depocenter of the lake compared to the margins. Excluding (mass transport deposits MTDs) from chronology yields a normal, event‐free age‐depth model for core. Moreover, time intervals of units missing at the exposed sections of the lake margin are synchronous with intervals of mass transport deposits (MTDs) at the deepest lake floors. In the deep core, the recurrence interval range of MTD with thickness > 1 cm is ~ 100–300 years, while that of the thick MTD (>50 cm) is ~ 2,500 years, twice the recurrence interval of the seismites at the lake's margins. The ~1,000 year recurrence at the lake's margins lies within the ranges that have been calculated for ~M6.5–7 earthquakes. The significantly higher figure shown by depocenter core suggests activity on various faults and the response of the lake sediments in the entire Dead Sea basin. Overall, an unprecedented chronology of seismic activity was achieved for the late Pleistocene Lisan Formation providing a framework of earthquake activity in the vicinity of the Dead Sea basin during the period of the last high lake stand.

“…These rates are found to be in general agreement with long‐term geological and geomorphological estimates [e.g., Garfunkel et al ., 1981, Joffe and Garfunkel , ; Klinger et al ., ; Ferry et al ., ]. All recent GPS measurements along the Arava Valley, in the southern part of the DSF, suggest a slip rate of ~5 mm/yr [ Le Beon et al ., ; Al‐Tarazi et al ., ; Sadeh et al ., ; Masson et al ., ].

“…Several attempts were made to geodetically measure the current slip rates along the DSF. Precise Global Positioning System (GPS) measurements reveal a relative slip rates in the range of 3.8–6.0 mm/yr along the southern and central parts of the DSF [e.g., McClusky et al ., ; Wdowinski et al ., ; Reilinger et al ., ; Le Beon et al ., ; Al‐Tarazi et al ., ; Sadeh et al ., ; Masson et al ., ]. These rates are found to be in general agreement with long‐term geological and geomorphological estimates [e.g., Garfunkel et al ., 1981, Joffe and Garfunkel , ; Klinger et al ., ; Ferry et al ., ].…”

We geodetically investigate the interseismic deformation along two neighboring sections of the Dead Sea Fault in Israel and present first clear evidence for shallow creep along this fault. We obtain the velocities of near‐fault GPS campaign stations across the northern section of the Jordan Valley Fault (JVF) and the Jordan Gorge Section (JGS) that were surveyed each year between 2009 and 2015. The JVF extends from the northern shore of the Dead Sea to the eastern shore of the Sea of Galilee, and the JGS extends from the Sea of Galilee to the Hula Basin. We infer a slip rate of ~4.1 mm/yr and a locking depth of ~10 km for both sections. Data analysis indicates that while the JGS is found to be fully locked above the locking depth, the northern section of the JVF is found to be creeping from a depth of 1.5 ± 1.0 km to the surface, with a creep rate of 2.5 ± 0.8 mm/yr. Our observations also suggest that the current slip rate of the fault at the western margin of the Jordan Valley is minor, less than the GPS velocities uncertainties.

“…The fault is the primary seismogenic structure of the plate boundary between the Sinai subplate and the Arabian plate (Salamon et al, 1996). Because of the low slip rates of the two plates (4-6 mm=yr; Masson et al, 2015), strong earthquakes (i.e., M w > 7) are fortunately rare, but not impossible (one approximately every 250 years). The last earthquake causing severe damage for large parts of the region was the 1927 Jericho event with a local magnitude M L 6.2 (Avni et al, 2002) that only the elderly in today's population remember.…”

We derive a probabilistic seismic-hazard model for the Dead Sea region to allow for seismic risk estimation, which will be part of a subsequent study. This hazard model relies as much as possible on data-driven approaches, utilizing a seismic catalog compiled for the region by integrating data from different sources. We derive seismicity models using two different smoothing approaches and estimate a hypocentral depth distribution from historical observations. We do not include paleoseismological evidence apart from the observed seismicity. Because ground-motion records are sparse in the region, we formulate the model in the European Macroseismic intensity scale from 1998. However, the collected macroseismic intensity data are still too few to derive a local intensity prediction equation (IPE). Thus, we choose among existing equations derived for different regions and combine them in a logic tree. Here, motivated by Scherbaum et al. (2010), we propose a two-step approach to select the IPEs for the logic tree. First, we cluster a set of 10 candidate IPEs to identify groups of models that can be considered similar with respect to the distribution of the predicted values for a selection of the explanatory variables (i.e., magnitude and distance), using a k-mean approach (Steinhaus, 1956). Then, we apply different ranking techniques (Scherbaum et al., 2009;Kale and Akkar, 2013) to identify within each cluster the most suitable model to be included in the logic tree. The resulting hazard models are consistent with existing probabilistic seismic-hazard models for the region. We estimate a moderate-to-high hazard of intensity grade VII-VIII with 10% probability of exceedance within 50 years in close vicinity to the Dead Sea transform fault, the dominant seismogenic structure in this region.
