Paper Abstract

The Haiyuan fault is a major active left-lateral fault in the northeast edge of Tibet-Qinghai Plateau. Studying this fault is important to understanding current deformation of the plateau and the mechanism of continental deformation. IPTA (Interferometric Point Target Analysis) can be summarized as an iterative improvement of the model parameters to achieve an optimal match to observe interferometric phases. The analysis is done for a selected set of points which correspond to point target candidates, and is a collection of tools to exploit the temporal and spatial characteristics of interferometric signatures collected from point targets to accurately map surface deformation histories, terrain heights, and relative atmospheric path delays. Surface deformation in the Haiyuan fault is about 4-6mm/y.
