The Jordan-Dead Sea Transform (JDTZ) is an active tectonic zone which is located between the Dead Sea in the north and the Gulf of Aqaba in the south and extends approximately 245 km. The JDTZ has a complicated geomorphological setting and varied geology and it contains a number of active faults that were associated with several significant destructive earthquakes in the region. This research was initiated to develop a morphometric digital approach to examine the mountain front geomorphic form along the Jordan-Dead Sea Transform Zone to obtain intensive analysis of its potential as an indicator of seismic activity.

520 $a The Jordan-Dead Sea Transform (JDTZ) is an active tectonic zone which is located between the Dead Sea in the north and the Gulf of Aqaba in the south and extends approximately 245 km. The JDTZ has a complicated geomorphological setting and varied geology and it contains a number of active faults that were associated with several significant destructive earthquakes in the region. This research was initiated to develop a morphometric digital approach to examine the mountain front geomorphic form along the Jordan-Dead Sea Transform Zone to obtain intensive analysis of its potential as an indicator of seismic activity.
520 $a Four ASTER scenes were used as a visual digital data reference to locate geomorphic forms along the mountain fronts in the study area. Using the ASTER generated DEMs of +/-10m vertical accuracy as a base elevation reference layer, several significant mountain fronts and valley profiles were digitized using GIS technology to precisely determine their morphometric indices. The mountain front sinuosity (Smf) and the ratio of valley floor width to valley height (Vf) morphometric indices were utilized to analyze the several mountain fronts and valleys in the JDTZ to determine their tectonic activity.
520 $a The final morphometric analysis of Smf results indicated two major tectonic activity classes within the JDTZ. The active tectonic class 1 values range from 1.00 to 1.30 while the moderate to less active class 2 values are >1.30. On the other hand, the Vf analysis results suggest the existence of three tectonic activity classes. The active tectonic class 1 values range from ≤0.09 to 0.50, the moderate to less active class 2 values range from 0.51 to 1.88, and the less active (inactive) class 3 values are >1.88.
