Ambient Noise Interferometry and Applications to Environmental Monitoring

• Hydrological processes with surface displacement data

• Seismic velocity changes and rock physics for shallow interaction with surface temperature

• Ambient noise interferometry sensitivity

• Ambient noise interferometry of borehole geometry (seismometer and DAS)

• Time-lapse dv/v tomography

Extracting wavefield from CCF of MiDAS 

• Applying ambient noise interferometry to DAS data from downhole cable sections and surface sections of the DAS array at Milun Fault.

• Investigating the wavefields in NCFs from high-resolution DAS data

• Monitoring temporal changes associated with near-surface processes

Seismological investigations in Thailand

Seismological studies in Thailand were sparked after the devastating 2004 Tsunami. The national seismic monitoring network under TMD consists of 50~ stations nationwide. 

• My goal is to use mature methods such as traveltime tomography, receiver function, etc. to investigate velocity structures in Thailand. The preliminary study from seismic methods would be valuable for understanding the geodynamics, seismotectonics, and disaster mitigation in this region.

• Refine the earthquake catalog by auto-picking and relocation in Thailand using machine-learning packages
