Investigating Subglacial Water‐Filled Cavities by Spectral Analysis of Ambient Seismic Noise: Results on the Polythermal Tête‐Rousse Glacier (Mont Blanc, France) Open
Polythermal glaciers can trap considerable volumes of liquid water with the potential to generate devastating outburst floods. This study aims to identify water‐filled subglacial reservoirs from ambient seismic noise collected by moderate‐…

Detection and localization of ice cavitiy using ambient seismic noise Open
Subglacial cavities may trap a considerable quantity of liquid water, causing devastating outburst floods in densely populated mountain areas. Dedicated studies aimed at identifying such intraglacial cavities at an early stage of their for…

Challenges in shallow target reconstruction by 3D elastic full-waveform inversion — Which initial model? Open
Elastic full-waveform inversion (FWI) is a powerful tool for high-resolution subsurface multiparameter characterization. However, 3D FWI applied to land data for near-surface applications is particularly challenging because the seismograms…

High-frequency ambient noise surface wave tomography at the Marathon PGE-Cu deposit (Ontario, Canada) Open
<p>Ambient noise surface wave tomography (ANSWT) is an environmentally friendly and cost-effective technique for subsurface imaging. In this study, we used natural (low-frequency) and anthropogenic (high-frequency) noise sources to m…

Full-waveform matching of VP and VS models from surface waves Open
SUMMARY The analysis of surface wave dispersion curves (DCs) is widely used for near-surface S-wave velocity (VS) reconstruction. However, a comprehensive characterization of the near-surface requires also the estimation of P-wave velocity…
