“…Those structures branch from the western Dead Sea fault partly following older Turonian-Senonian faults (Ginat et al, 1998). Those assumptions are supported by studies by Freund et al (1968); Kafri and Heimann (1994) and Matmon et al (1999), who proved the adjustment of the drainage system to morpho-tectonic features in the study area. The northern-oriented (0-5 • ) morphological lineaments explicitly stem from lithological edges and align along the western fault of the Dead Sea, most likely relating them to the Dead Sea stress field.…”

Abstract. In this paper we present a semi-automatic method to infer groundwater flow-paths based on the extraction of lineaments from digital elevation models. This method is especially adequate in remote and inaccessible areas where in-situ data are scarce. The combined method of linear filtering and object-based classification provides a lineament map with a high degree of accuracy. Subsequently, lineaments are differentiated into geological and morphological lineaments using auxiliary information and finally evaluated in terms of hydro-geological significance. Using the example of the western catchment of the Dead Sea (Israel/Palestine), the orientation and location of the differentiated lineaments are compared to characteristics of known structural features. We demonstrate that a strong correlation between lineaments and structural features exists. Using Euclidean distances between lineaments and wells provides an assessment criterion to evaluate the hydraulic significance of detected lineaments. Based on this analysis, we suggest that the statistical analysis of lineaments allows a delineation of flow-paths and thus significant information on groundwater movements. To validate the flow-paths we compare them to existing results of groundwater models that are based on well data.

“…Lartet (1869) interpreted the movement along the Dead Sea Rift to be strike-slip as the major movement and normal as a minor one. This interpretation was subsequently supported by Quennel (1956 and, Freund (1965), Freund (1966 and1981), Freund et al (1968 and, Neev (1975), Bartov et al (1980), Garfunkel (1981) and Garfunkel et al (1981). Others (Vorman, 1961;Michelson, 1982;Bahat and Rabinovitch, 1983) claim that the rift evolved as a combination of vertical (dip-slip) and horizontal (left-lateral) movement.…”

Abstract. This work presents the first palaeostress results obtained from fault-slip data along the eastern margins of the Dead Sea Rift (also named Dead Sea Transform) in South-western Jordan. Stress inversion of the fault-slip data was performed using an improved Right-Dieder method, followed by rotational optimisation. Fault-slip data (totalling 2773) include fault planes, striations and sense of movements, obtained from outcrops ranging in age from Neoproterozoic crystalline basement to Holocene sediments. The data were inverted to determine 88 different palaeostress tensors. Eight palaeostress tensor groups (stages) have been identified, ranging from the Late Neoproterozoic to the Holocene period, and have been correlated with the tectonic evolution of the Dead Sea Rift.The new palaeostress data evidence a general clockwise rotation with time of the S Hmax axis from an E-W trend in the Cretaceous to a N-S trend in the Pleistocene. Two stages can be distinguished in this rotation. The older one marks the change of the S Hmax axis from E-W to NW-SE (about 50 • rotation), and took place in the Miocene. The second one illustrates the changes of the S Hmax axis from NW-SE to NNW-SSE to N-S (38 • rotation), taking place during the Pleistocene (the last 6 Ma). The data also show the appearance of E-W extension in the Late Pleistocene, superimposed on the Dead Sea Stress Field. We therefore suggest that the Dead Sea Rift system formed in a combination of strike-slip and dip-slip movements.

“…Global positioning system (GPS) observations provide rates of the present left-lateral displacement along the DST fault in the range of 3.5-4.0 mm per year (Wdowinski et al, 2004;Gomez et al, 2007), but geological data provide evidence for faster rates ranging from 5 to 10 mm per year of long-term displacements in the past starting from the initiation of the DST 20-15 Ma ago (Garfunkel, 1981;Chu and Gordon, 1998). On the basis of geological information, the total displacement in a segment of the DST between the Gulf of Aqaba and the Dead Sea has been estimated to be 105 km (Freund et al, 1968;Bartov et al, 1980;Garfunkel et al, 1981). To the north of the Dead Sea, the displacement is considerably less (Garfunkel, 1981).…”

Seismic structure beneath the Gulf of Aqaba and adjacent areas based on the tomographic inversion of regional earthquake data

Abstract. We present the first 3-D model of seismic P and S velocities in the crust and uppermost mantle beneath the Gulf of Aqaba and surrounding areas based on the results of passive travel time tomography. The tomographic inversion was performed based on travel time data from ∼ 9000 regional earthquakes provided by the Egyptian National Seismological Network (ENSN), and this was complemented with data from the International Seismological Centre (ISC). The resulting P and S velocity patterns were generally consistent with each other at all depths. Beneath the northern part of the Red Sea, we observed a strong high-velocity anomaly with abrupt limits that coincide with the coastal lines. This finding may indicate the oceanic nature of the crust in the Red Sea, and it does not support the concept of gradual stretching of the continental crust. According to our results, in the middle and lower crust, the seismic anomalies beneath the Gulf of Aqaba seem to delineate a sinistral shift (∼ 100 km) in the opposite flanks of the fault zone, which is consistent with other estimates of the left-lateral displacement in the southern part of the Dead Sea Transform fault. However, no displacement structures were visible in the uppermost lithospheric mantle.
