Abstract: The ongoing collision between the Indian and Eurasian plates has produced one of the most extensive regions of continental deformation on Earth, spanning from the Himalayas through the Tibetan Plateau to Central Asia. Continents deform through a combination of continuous distributed strain and localised deformation along lithospheric-scale faults. However, the relative importance of these processes – and the extent to which major fault zones control the overall deformation field – remain uncertain, partly due to the limited spatial resolution of previous geodetic observations. In this talk, I will examine earthquake-cycle deformation associated with the 2021 Mw 7.4 Maduo earthquake in eastern Tibet, revealing the behaviour of a low-straining fault throughout the earthquake cycle and the distributed nature of seismic hazard beyond major faults. I will then present new constraints on interseismic strain across southeastern Tibet, showing that total deformation is nearly equally partitioned between fault-localised and diffuse off-fault strain. Finally, I will introduce a faulted thin viscous shell model that explicitly represents discontinuities within a continuous medium, offering new insight into how major fault systems modulate the large-scale dynamics of the India-Eurasia collision.
