Abstract:<p>Distributed Acoustic Sensing (DAS) is becoming increasingly popular due to its high spatial and temporal resolution. DAS holds great potential for geohazard applications as, in principle, anything affecting the strain on a fibre optic cable section can be measured. Examples are passing seismic surface waves and ambient temperature changes.&#160; This presentation demonstrates the feasibility of DAS for quick clay monitoring, and presents data from a field trial in Rissa, Norway.<… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
