Research Title: Crustal deformation modelling in the Krafla area based on realistic Earth properties


The objectives of this research project are: i) to constrain the parameters of Earth properties based on geodetic observations of crustal deformation (GNSS, InSAR, leveling, etc.) and other observations (borehole, seismic tomography, thermal structure, and resistivity data); ii) to evaluate the poro-elastic properties of the geothermal field and to develop a 3D model of the elastic, visco- and poro-elastic structure of the area; iii) to interpret shallow deformation signals and investigate their origins from geothermal utilization and natural processes; iv) to re-evaluate and improve the models of past and present deformation process, e.g., the Krafla fires and the post-eruptive period. Besides, the surface deformation maps from geodetic observations will be updated in this project this project.

Scientific Background

I graduated from Wuhan University, China, in 2018 with a BSc. in Geodesy and Geomatics Engineering. Motivated by a strong interest on earth sciences, I continued to take MSc. in Geodesy and Survey Engineering in Wuhan University, where I studied GNSS time series analysis and crustal deformation monitoring with deformation and strain maps. During my MSc., I participated in a Natural Science Foundation of China (NSFC) project (reconstructing continuous deformation maps with scattered GNSS stations), a National Key R&D project of China (modelling seasonal variations in GNSS time series, respectively based on mathematical methods and geophysical models) and a Natural Science Foundation of Hubei Province, China, project (robust trend estimation for GNSS stations with multisource time series). In Oct. 2021, School of Geodesy and Geomatics, Wuhan University, hired me as an assistant engineer to develop a software generating crustal deformation maps with GNSS data. I also have been working on the correlation analysis methods for non-stationary time series and the hydrological analysis of North China Plain.
