Distributed acoustic sensing (DAS) is an emerging technology that repurposes a fiber-optic
cable as a dense array of strain sensors. This technology repeatedly **s a fiber with laser …

Distributed acoustic sensing (DAS) is a new, relatively inexpensive technology that is rapidly
demonstrating its promise for recording earthquake waves and other seismic signals in a …

Sparse seismic instrumentation in the oceans limits our understanding of deep Earth
dynamics and submarine earthquakes. Distributed acoustic sensing (DAS), an emerging …

Understanding physical processes prior to and during volcanic eruptions has improved
significantly in recent years. However, uncertainties about subsurface structures distorting …

Abstract Distributed Acoustic Sensing (DAS) is a novel tool in array seismology that
measures the phase of backscattered laser pulses traveling in a fiber‐optic cable, and …

The discipline of seismology is based on observations of ground motion that are inherently
undersampled in space and time. Our basic understanding of earthquake processes and our …

In this paper, deep learning models trained with real seismic data are proposed and proven
to detect earthquakes in fiber-optic distributed acoustic sensor (DAS) measurements. The …

We compare the performance of a downhole distributed acoustic sensing (DAS) fiber‐optic
array with that of conventional geophones. The downhole collocated arrays are part of the …

Detecting pinhole leaks in long-haul buried gas pipelines is challenging due to weak leak
signals and large spans. Fiber-optic distributed acoustic sensing (DAS) technology offers …

Accurate ground motion prediction requires detailed site effect assessment, but in urban
areas where such assessments are most important, geotechnical surveys are difficult to …
