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

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 …

Linear infrastructures, such as railways, tunnels, and pipelines, play essential roles in
economic and social development worldwide. However, under the influence of geohazards …

Distributed acoustic sensing (DAS) is an emerging technology for acquiring seismic data
due to its high-density and low-cost advantages. Because of the harsh acquisition …

Icequakes, microseismic earthquakes at glaciers, offer insights into the dynamics of ice
sheets. For the first time in the Antarctic, we explore the use of fiber optic cables as …

Distributed Acoustic Sensing (DAS) is gaining vast popularity in the industrial and academic
sectors for a variety of studies. Its spatial and temporal resolution is ever helpful, but one of …

Subglacial water flow strongly modulates glacier basal motion, which itself strongly
influences the contributions of glaciers and ice sheets to sea level rise. However, our …

Vadose zone soil moisture is often considered a pivotal intermediary water reservoir
between surface and groundwater in semi-arid regions. Understanding its dynamics in …

Firn densification profiles are an important parameter for ice‐sheet mass balance and
palaeoclimate studies. One conventional method of investigating firn profiles is using …

The distributed acoustic sensing (DAS) technology that has emerged in recent years,
combined with existing optical cables for earthquake monitoring, has the advantages of low …
