Matched Field Processing of train vibrations for opportunistic surface wave tomography Open
Railways are exposed to geotechnical hazards such as sinkholes or subsidence because they encounter many geological settings. Railway subsurface imaging is thus important in order to detect small anomalies in the elastic properties of the …

Characterization of train kinematics and source wavelets from near-field seismic data Open
SUMMARY Train traffic is a powerful source of seismic waves, with many applications for passive seismic imaging. Seismic signals were recorded a few metres away from the railway track. These records display harmonious waveforms below 15 Hz…

Permanent passive seismic monitoring of the near-surface ground beneath railways using trains as sources Open
The deformation or collapse of tracks, due to sinkhole formation beneath railway platforms, is a natural hazard that can affect train traffic regularity, cause extra maintenance costs, but also lead to crucial safety issues.In this paper, …

A case study for railway underground imaging using trains as seismic signal for sinkhole and subsidence phenomena prevention Open
Railway tracks are particularly exposed to the danger represented by sinkholes, a type of naturally forming underground cavity.Preventing the potentially severe outcomes through early detection represents a challenge for underground imagin…

Seismic emissions from a passing train: turning ambient noise into a controlled source Open
Train traffic is a powerful source of seismic vibrations. Recent studies have shown that trains illuminate geological structures both at the crustal and the geotechnical scale. Existing works have been able to reconstruct approximately the…

Ambient seismic noise processing to monitor sea dikes: the case of Noirmoutier, France Open
The use of ambient noise for passive seismic imaging has evolved into a cutting-edge, low-cost, and environmentally acceptable method of exploring the subsurface. This technique dispenses with active seismic sources, alternatively uses amb…

Characterization of ambient seismic noise sources for long term monitoring of a sea dike: preliminary results of the SEEWALL project. Open
Protection against sea submersion is a key point for the management of coastal areas. Operators need tools to monitor the aging of the sea dikes in order to reduce the risk of catastrophic events such as the Xynthia storm that occurred in …
