Monitoring lithospheric motions bySatellite Geodesy

In this project we studied the lithospheric motion and the Earth’s mass change in terms of gravity variation, using a combination of geodetic satellite data and non-geodetic observations.

Understanding global and local Earth’s dynamic processes are important to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). The processes are largely affected by the Earth's mass distribution and redistribution, which can be quantified and modelled using simultaneous and complementary data from various geoscience and environmental near earth-orbiting artificial satellites. In this PhD project (funded partially by J. Gust. Richert foundation), we studied the lithospheric motion and the Earth’s mass change in terms of gravity variation, using a combination of geodetic satellite data and non-geodetic observations.

Goals

  • To study the Earth’s gravity in terms of Groundwater storage change, associated e.g. to permafrost thawing and groundwater/ oil depletion.
  • To monitor and analyze the ground surface deformation associated with the sub-surface geology type and water/oil depletion using InSAR technique.
  • To determine sub-crustal horizontal stress and its temporal changes caused by geodynamical (mantle convection) using gravimetric approach.
  • To investigate the relationship between the isostatic state of the lithosphere and seismic activities.
