Monitoring seismic velocity changes at Turrialba using ambient seismic noise interferometry

2023
Seismic Ambient Noise Interferometry (SNI) is a prevalent tool for monitoring volcanic and associated seismic hazards. Reconstructing Empirical Green’s Functions by cross-correlation (CCs) of continuous seismic noise recordings allows us to track variations in seismic wave velocity with time, providing ongoing insights into the stress state of the ...

Seismic attenuation from seismic ambient noise recordings

The eastern part of the Vienna Basin represents Austria's primary target for deep geothermal exploration. Effective geothermal resource assessment requires detailed knowledge of subsurface rock properties, including porosity, permeability, and fluid content.

Constraining 6C-observed seismic anisotropy from seasonal ambient seismic noise

Our recent theory shows that the 6C ground motion (three-component translation and three-component rotation) of ambient seismic noise is capable of measuring the local seismic anisotropy using azimuth-dependent 6C-based cross-correlation functions. However, seasonal variations in ambient seismic noise result in large uncertainties in local velocity ...

Elastic full-waveform inversion of seismic ambient noise

The Leading Edge
Elastic full-waveform inversion (FWI) is appealing for an enhanced integration of wave physics propagation and the resulting improved characterization of the subsurface due to the reconstruction of P- and S-wave velocity models. While the high computational cost of elastic FWI can be controlled using adequate numerical methods, the increase in the ...
