Continental deformation in Asia from a combined GPS solution

After decades of research on continental tectonics, there is still no consensus on the mode of deformation of continents or on the forces that drive their deformation. In Asia the debate opposes edge‐driven block models, requiring a strong lithosphere with strain localized on faults, to buoyancy‐driven continuous models, requiring a viscous lithosphere with pervasive strain. Discriminating between these models requires continent‐wide estimates of lithospheric strain rates. Previous efforts have relied on the resampling of heterogeneous geodetic and Quaternary faulting data sets using interpolation techniques. We present a new velocity field based on the rigorous combination of geodetic solutions with relatively homogeneous station spacing, avoiding technique‐dependent biases inherent to interpolation methods. We find (1) unresolvable strain rates (
