Mathematical Imaging and Geophysics Group

Develop advanced mathematical imaging tools to investigate the Earth’s interior

Mathematical Imaging and Geophysics Group (MIG) is primarily focused on developing advanced mathematical tools to better image the interior of the Earth at a variety of scales, namely, from the global map of the crust and mantle to the detailed subsurface structure of a hydrocarbon/geothermal reservoir. Through developing novel mathematical modelling tools and the state-of-the-art seismic imaging technology, analyzing the full waveform contents of high-quality seismic data, and relying on high performance computing, we aim to gain insight into the geodynamic processes of the Earth’s interior and provide advanced methods to solve realistic problems faced by modern oil-and-gas Exploration/Production companies and contractors.

  • December 20, 2021: LIU Yongsheng passed his PhD thesis defense. Congratulations.

Research

*
Mathematical Modelling and Inversion
We develope advanced numerical schemes to solve partial differential equations such as the eikonal equations and acoustic/elastic/visoelasitc wave equations to accurately model the propagation of seismic waves in complex media.
Earthquake Seismology
Earthquake seismology is one of the most powerful tools to study the interior of the earth.
Exploration Geophysics
Exploration geophysics is an applied branch of geophysics. It aims to explore the first few kilometers of the earth’s crust by identifying rock and/or fuild types and structures.

Softwares

Those softwares are still under development and to be released soon. Please feel free to request for them, improve the codes, and send your feedback!

Body-wave Traveltime Tomography
We develop ray-based and ray-free body-wave traveltime tomography methods to invert isotropic and anisotropic (azimuthal/radial anisotropy) velocities.
SEM-FK Hybrid Method
We develop a 2-D/3-D hybrid method that interfaces the spectral-element method (SEM) with the frequency-wave number (FK) technique to model the propagation of teleseismic plane waves beneath seismic arrays.
