Research Projects

1. Understand the structure and deformation in the crust and upper mantle structure in southeastern Tibet from analysis of ambient noise and surface wave array data

Comparison of GPS velocity vectors (red arrows) with Vs azimuthal anisotropy at 10 km depth (black bars)

 

2. Ambient noise interferometry: recovery of surface wave green's function from correlation of direct waves, coda waves, and ambient noise (Yao et al., PEPI, 2009)

3. Ambient noise analysis and tomography: how to estimate uneven ambient noise energy distribution and its effect on dispersion measurements and tomographic models; other applications of ambient noise or seismic interferometry (Yao and van der Hilst, GJI, 2009)

 

 

Research Collaboration

In the past five years, I have been actively collaborating with scientists in the US, China, France, Italy, and the Netherlands to (1) develope new techniques for surface wave tomography and ambient noise interferometry, and to (2) understand the crust and upper mantle structure and deformation in the Tibetan Plateau, North China Craton, and Continental China, Taiwai and Taipei Basin, etc. The past and current collaborators are:
