I am interested in the interdisciplinary study of seismic hazard in the continental interior through a combined approach using remote sensing, seismology and geomorphology. My DPhil project is focused on the NE Tibetan Plateau, where the ∼1000-km-long strike-slip Kunlun and Haiyuan Faults and the thrust belt in the Qilianshan accommodate the ~15mm/yr shortening across the region. The aim of my project is to construct a regional earthquake rate map from a strain rate map using the Gutenberg-Richter Relationship. The high-resolution strain rate map will be derived from 5 years of Sentinel InSAR data. The strain-rate to earthquake-rate conversion will be hinged upon the magnitude of the 1920 Haiyuan Earthquake which has long been reported as M 8.7. However, this number is being challenged in recent literature. Hence, using offset measurements from the high-resolution Pleiades satellite data and modelling of the digitised 100-year old seismograms, I re-estimate the magnitude of this earthquake to be ~ Mw8.0 so as to improve the seismic hazard assessment of the region.
