A long deformation record (~16.5 ka) showing nonsteady earthquake recurrence is established for the Aksu thrust (Tianshan, China) on the basis of cosmogenic 10Be dating of faulted surfaces. Topographic leveling across the Aksu fault scarp indicates up to ∼10 m uplift across a moraine abandoned ~16.5 ka and similar uplift of ~6 m across two inset surfaces yielding ages of ~12.5 and ~5 ka....

Long-term elasticity in the continental lithosphere ; modelling the Aden Ridge propagation and the Anatolian extrusion process

In: Geophysical Journal International, 2003, vol. 153, p. 111-132

The evolution of the Gulf of Aden and the Anatolian Fault systems are modelled using the principles of elastic fracture mechanics usually applied to smaller scale cracks or faults. The lithosphere is treated as a plate, and simple boundary conditions are applied that correspond to the known plate boundary geometry and slip vectors. The models provide a simple explanation for many observed...
