Seismic Attenuation Extraction From Traffic Signals Recorded by a Single Seismic Station
Geophysical Research Letters, 2023 Seismic ambient noise contains rich information about the physical properties of the critical zone. From the motor vehicle noise, we extract the daily seismic attenuation by quantifying the linear relationship between the frequency and amplitude ratio of

Full wavefield inversion of ambient seismic noise [PDF]
Geophysical Journal International, 2018 We formulate a full wave field inversion for ambient seismic noise recorded by large and dense seismograph arrays. Full wave field inversion exploits the constraints on the gradients of the wave field that array data inherently possess. We pose full wave field inversion as a partial differential equation (PDE) constrained inverse problem resulting in a

Continuous isolated noise sources induce repeating waves in the coda of ambient noise correlations
Seismica, 2023 Continuous excitation of isolated noise sources leads to repeating wave arrivals in cross correlations of ambient seismic noise, including throughout their coda. These waves propagate from the isolated sources.

Seismic Periodic Noise Attenuation Based on Sparse Representation Using a Noise Dictionary
Applied Sciences, 2023 Periodic noise is a well-known problem in seismic exploration, caused by power lines, pump jacks, engine operation, or other interferences. It contaminates seismic data and affects subsequent processing and interpretation.
