Ambient Noise Interferometry and Applications for Environmental Monitoring

• Time-lapse dv/v tomography

• Low-frequency dv/v changes and surface temperature

• Ambient noise interferometry sensitivity

Hydrogeophysics

Hydrological processes, from rainfall to water storage and subsequent ground deformation, are still not fully understood. Combining observational data, modeling, and applied methods can provide a more comprehensive understanding of these complex processes and their environmental impacts. 

• Effects of mechanical loading and pore pressure on aquifers and seismic velocity changes

• Comparison of GWL change with surface displacement data

• Interaction of tidal strain with diurnal GWL variations

• Co-seismic GWL change

Distributed Acoustic Sensing (DAS) Applications 

• Milun Fault Drilling project: 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
