Title: Integrating Satellite Observations and Modeling Approaches to Study Subduction Zone Hazards
Abstract:
Accurate estimates of interseismic coupling on a megathrust are critical for assessing seismic and tsunami hazards, yet are limited by near-trench geodetic coverage and challenges in modeling realistic subduction zones. In this talk, I present satellite geodetic observations from ALOS-2 spanning 2015 to 2022 to investigate the strain distribution across the overriding plate of the Rakhine-Bangladesh megathrust, including Bangladesh and the Indo-Myanmar Ranges. I will also present an alternative explanation for the apparent gap between the locked part of the megathrust and the location of episodic tremor and slip in Cascadia using models with realistic material properties, and show how seafloor geodesy can help resolve this problem.
Biography: Jeng Hann Chong is a recent PhD graduate from the University of New Mexico. He specializes in processing InSAR, along with modeling tectonic deformations and mass wasting processes. He obtained his Associate Degree in Science at Taylor’s University of Malaysia, then continued his studies at the University of Maryland with a degree in Geology, and later obtained a Master’s degree at California State University of Northridge. He recently obtained the Alexander von Humboldt Postdoctoral Fellowship to pursue a postdoctoral position at GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany.
