Figure 2. Results of numerical modeling experiments. Boundary conditions are plotted in red in Figure 1. Shorelines are in black. RMS zone is the root mean square calculated for global positioning system sites located in zone bound by the two dashed black lines. A: Northwestsoutheast Eurasia-Nubia transpression. Homogeneous rheology Young’s modulus E = 10 11 Pa (white domain) and Poisson’s ratio ν = 0.25. B: Northwest-southeast Eurasia-Nubia transpression including Alboran Sea weak zone. Shaded zone: E = 1010 Pa and ν = 0.25. C: Northwestsoutheast Eurasia-Nubia transpression including Alboran Sea weak zone and a horizontal basal traction. Rheology is the same as in B. Black hatched area is the horizontal traction patch with a velocity of 3.6 mm/yr, 214°N directed (open black arrow), applied beneath the elastic plate at 30 km depth.
