... Ren et al. (2019) show the advantages of using interleaved envelope and least-squares misfit functions in shallow-seismic FWI. Borisov et al. (2022) show that the misfit function based on graph-space optimal transport is more robust against the poor initial model than the leastsquares misfit function in FWI. ...

... They show that ROWI is more robust and computationally more efficient than the conventional FWI. Borisov et al. (2021) confirm that using a single shot is more efficient than using more shots per iteration. Köhn et al. (2021) and Pan et al. (2021) prove the validity of ROWI in field-data applications. ...

... In addition, the data processing phase, which includes raw image combination, filtering, muting and the combination of dispersion images, is crucial for accurately interpreting the complex wavefield data into reliable geological information 14,17,22 . While existing literature provides a foundational understanding of these parameters in the context of both active and passive MASW 4,13,15 , there remains a gap in specific research dedicated to optimizing these parameters for passive roadside surveys in urban settings. ...

... The original research project was designed to evaluate the applicability of body-and surface-waves propagation to detect the presence of voids and delineate mines. In this effort we expand our preveous work from 2016, which analyzed seismic data using the multi-channel analysis of surface waves (MASW) and the backscatter analysis of surface wave (BASW) methods with two recently developed imaging methods for detecting tunnels, cavities, or other shallow anomalies (Peterie et al., 2021), the convertedsurface-wave imaging (CSWI) and the converted-surfacewave amplitude stack (CSWAS). ...

... In this paper, we present a novel method to detect underground cavities using crossborehole ground-penetrating radar (GPR). The problem of detecting underground cavities has been considered since before the Common Era, yet it remains relevant to this day [1]. Electromagnetic methods, and ground-penetrating radar in particular, have been shown to perform particularly well on this problem [2,3]. ...

... Shear (SH) wave propagation is not sensitive to pore fluids, therefore shear wave data is considered to provide reliable results for geological structure interpretation (Lellouch and Reshef, 2017). The S-wave data have the advantages of low attenuation and high resolution and can accurately describe near-surface geologic structures (Zhu et al., 2016;Chen et al., 2017;Peterie et al., 2020). With the continuous progress in seismic exploration technology and the upgrading of S-wave vibrators, seismic S waves (SV-SV and SH-SH waves) have been investigated for data acquisition, processing, and interpretation (Dai et al., 2022). ...

To date, however, FWT has only been used to study the near surface on a handful of occasions (e.g., Cai & Zelt, 2022;J. Chen et al., 2017;Köhn et al., 2018;X. Liu et al., 2022;Sheng et al., 2006;W.

Others have primarily inverted surface waves for archeological or engineering applications (e.g., Köhn et al., 2018;Pan et al., 2019;Smith et al., 2019;Wang et al., 2019c) or inverted surface waves extracted from ambient noise data to study CZ structure and weathering (W.

... In land seismics, a surface source generates high-amplitude surface waves. Although these are widely used in global and regional seismology (Simons et al., 1999) and shallow engineering (Smith et al., 2018) studies, they are typically treated as noise within the seismic exploration community. In this study, we use surface waves to obtain valuable information on the shallow velocity structure which, if recovered, may reduce the need for statics estimation. ...

... The disposal-induced earthquakes are commonly attributed to the direct pore-pressure buildup spanning over a large area of highly permeable matrix and fault zones (Peterie et al. 2018). Besides the direct pore-pressure buildup, spatiotemporal correlations between surface-felt earthquakes and hydrocarbon production or underground water extraction can be explained based on the more complicated poroelastic effect (Fan et al. 2016(Fan et al. , 2019Zbinden et al. 2017;Goebel and Brodsky 2018;Haddad and Eichhubl 2020;Zhai et al. 2021;Tiwari et al. 2021). ...
