Distributed Acoustic Sensing for Urban Monitoring: Coverage Thresholds and Percolation
Khen Cohen, Ariel Lellouch
Distributed Acoustic Sensing (DAS) enables the repurposing of existing fiber-optic networks as ultra-dense, long-range seismic arrays for urban monitoring. However, constraints imp…
Buried Fiber-Optic Geolocalization with Distributed Acoustic Sensing
Khen Cohen, Natanel Nissan, Ofir Nissan +1
We present a scalable method for geolocalizing buried fiber-optic cables using Distributed Acoustic Sensing (DAS) and traffic-induced quasi-static seismic signals. Assuming access…
Training a Distributed Acoustic Sensing Traffic Monitoring Network With Video Inputs
Khen Cohen, Liav Hen, Ariel Lellouch
Distributed Acoustic Sensing (DAS) has emerged as a promising tool for real-time traffic monitoring in densely populated areas. In this paper, we present a novel concept that integ…
Detection and characterization of microseismic events from fiber-optic DAS data using deep learning
Fantine Huot, Ariel Lellouch, Paige Given +5
Microseismic analysis is a valuable tool for fracture characterization in the earth's subsurface. As distributed acoustic sensing (DAS) fibers are deployed at depth inside wells, t…
Low-magnitude Seismicity with a Downhole Distributed Acoustic Sensing Array -- examples from the FORGE Geothermal Experiment
Ariel Lellouch, Ryan Schultz, Nathaniel J. Lindsey +2
We show the capabilities of a downhole Distributed Acoustic Sensing (DAS) array in detecting, locating and characterizing low-magnitude earthquakes occurring in the vicinity of the…
Near-surface Characterization Using a Roadside Distributed Acoustic Sensing Array
Siyuan Yuan, Ariel Lellouch, Robert G. Clapp +1
Thanks to the broadband nature of the Distributed Acoustic Sensing (DAS) measurement, a roadside section of the Stanford DAS-2 array can record seismic signals from various sources…
