Article
Full-text available
Close to its southern end where it connects to the Red Sea rift, the Dead Sea strike‐slip fault (DSF) becomes trans‐tensional in the Gulf of Aqaba. Details of this transition, however, remain difficult to unravel as most of the active tectonic structures are located off‐shore. This study focuses on uplifted marine terraces located in the Gulf of Aq...

The largest (M8+) known earthquakes in the Himalaya have ruptured the upper locked section of the Main Himalayan Thrust zone, offsetting the ground surface along the Main Frontal Thrust at the range front. However, out-of-sequence active structures have received less attention. One of the most impressive examples of such faults is the active fault...

Strike-slip faults are generally described as continuous structures, while they are actually formed of successive segments separated by geometrical complexities. Although this along-strike segmentation is known to affect the overall dynamics of earthquakes, the physical processes governing the scale of this segmentation remain unclear. Here, we use...

Gulf of Aqaba is located at the southern end of the Dead Sea fault, which forms the boundary between the Arabian plate to the East and the Sinai micro-plate to the West. The Dead Sea fault accommodates mainly left-lateral strike-slip motion at a rate of about 5 ± 1 mm/yr. The 1995 MW=7.3 and the 1993 ML=5.8 earthquakes, both of which occurred in Gu...

Temporal distribution of earthquakes is key to seismic hazard assessment. However, for most fault systems shortness of large earthquake catalogues makes this assessment difficult. Its unique long earthquake record makes the Dead Sea fault (DSF) exceptional to test earthquake behaviour models. A paleoseismological trench along the southern section o...
Conference Paper
Full-text available
The Levant fault is a major tectonic structure located east of the Mediterranean Sea. It is a 1200 km-long left-lateral strike-slip fault, which accommodates the northward movement of the Arabic plate relatively to the Sinai micro-plate, with a ∼ 5mm/year slip-rate. This slip-rate has been estimated over a large range of time scales, from a few yea...
