In this blog we give a succinct introduction to Distributed Acoustic Sensing for the starting seismologist, or the interested reader. The blog is by no means a complete overview and serves as a starting point for you to understand DAS and get started with the data. It was written by SM ECS members Ana Nap and Katinka Tuinstra.   By now, Distributed Acoustic Sensing (DAS) is a pretty widely kn ...[Read More]

From light to waveform: how fiber-optic cables can be repurposed as seismic arrays

What is Distributed Acoustic Sensing (DAS) and why is it exciting? Any observational seismologist would agree that our understanding of subsurface structure and dynamics is in great part limited by our ability to acquire data at the right locations, with the necessary spatial and temporal resolution. However, although our ultimate objective would be to cover the Earth with high-quality, broadband ...[Read More]
