The Strain Shearing in the Collizion Zone of the Arabian and Eurasian Plates by the GPS Data and the Plate Rigidity Consideration
Journal Title: Հայաստանի գիտությունների ազգային ակադեմիայի տեղեկագիր․ Մեխանիկա - Year 2008, Vol 61, Issue 2
Abstract
By the FEA method it is defined the strain mode of the Arabian and Eurasian plate fragments in the zone of their Upper Cretaceous collision in Caucasus with consideration of the rigidity difference of those plates. The averaged ratio of elasticity modules of the plates is assessed by the comparison of the longitudinal wave velocity, known from the deep seismic sounding. The kinematics of the region is gained from GPS prospecting at 1988- 1997 on 37 points. The mode of the calculated strain sometimes corresponds to the behavior, anticipated by the other common data.
