The 1960s economic boom led to spread construction of large transport infrastructures. Many of these steel reinforced concrete structures attain their end of lifespans on this and next decade. With no major renewing plan, repairing and retrofitting are explored alternatives. A good …

Indonesia faces a unique combination of exposure to tsunamis, with dense coastal populations, intense seismic and volcanic activity, and multiple tsunami-generation mechanisms that can threaten shorelines with very little time for reaction.BMKG which is in charge of monitoring tsunamis faces 2 limitations: …

Distributed Acoustic Sensing (DAS) has recently emerged in seismological monitoring, converting standard telecommunication fiber optic cables into dense linear arrays of virtual seismic sensors. This capability is particularly relevant in underground environments, where existing infrastructure can be reused.This study presents results from …

Distributed Acoustic Sensing (DAS) has become a key technology for downhole seismic monitoring over the past decade, owing to its dense spatial sampling, operational simplicity, and cost efficiency. By converting fibre‑optic cables into continuous seismic sensors, DAS enables full‑depth borehole measurements that …

Distributed Acoustic Sensing is now a proven solution to record seismic data over long distances and dense geometries. It fundamentally differs however from traditional geophone or hydrophone measurements as the wavefield is sampled on a non-zero length instead of a point. In …

Monitoring groundwater and near-surface processes at high temporal resolution remains challenging, particularly in urban environments. Recent advances in passive seismology have demonstrated the potential of anthropogenic seismic sources to act as stable and repeatable signals for monitoring temporal variations in seismic velocity. …

Abstract Distributed acoustic sensing (DAS) enables cost‐effective, dense detection of seismic activity. However, the vast amount of data produced by DAS systems presents a significant challenge for labeling and analysis. Traditional supervised machine learning approaches require extensive labeling, which is time‐consuming and …

Distributed Acoustic Sensing (DAS) of ambient vibrations is a promising technique in the context of structural health monitoring of civil engineering structures. The methodology uses Rayleigh backscattered light from small deformations at different locations of the sensed fiber-optic cable, turning it into …

Abstract Passive seismic methods hold valuable information about the physical properties of the subsurface, enabling continuous, non‐intrusive monitoring of groundwater dynamics. This study introduces a novel methodology for monitoring near‐surface seismic attenuation variations using repetitive seismic noise sources. Our approach employs a …
