Yuan-Kai Liu is a first year MS student in the Department of Earth Science and Engineering at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. Working as a member in Crustal Deformation InSAR Group, his current research focused on ground deformation analyses of several subsiding calderas e.g. Wolf Volcano in the Galápagos archipelago and to explain the overlapping long and short wavelength deformation signals. To further understand the geological mechanism, his work combines analogue experiments with numerical modeling. The EGU 2017 poster presented photogrammetry results from analogue experiments including deformation characteristics from time-resolved digital image correlation and 3D spatial data. It says the ring faults development is responsible for the complex deformation patterns, providing an alternative explanation of the magma source.
