Distributed Acoustic Sensing

Distributed Acoustic Sensing (DAS) is a potentially transformative technology in the geosciences and engineering. The rapidly increasing interest in DAS arises from its use in continuous arrays that can be kilometers in length while providing spatial resolution of meters and frequency response from millihertz to kilohertz. This mailing list provides a forum for discussion on all topics related to DAS technology including: applications, installation, data acquisition, handling and processing of data, engineering and scientific technical development, and advertisement of upcoming events, workshops, meetings, or other opportunities in the DAS community.

Please join us for the next meeting of the DAS+ML (machine learning) working group, a subgroup of the Research Coordination Network <https://www.iris.edu/hq/initiatives/das_rcn>. We hold these monthly meetings the 3rd Thursday of every month at 1 pm Eastern US time. During these meetings we alternate between member presentations, publication discussions and guest speakers, on topics that cover DAS and machine learning intersections. This group has been active for about a year and half, but we a… [more]

The Southern California Seismic Network is seeking a postdoctoral scholar to research incorporating Distributed Acoustic Sensing (DAS) into Earthquake Early Warning (EEW). DAS provides an opportunity to add pre-existing telecommunications fibers to areas of the Network with low station density (e.g., offshore California). We seek proof of concept by using onshore fiber to answer some key questions regarding feasibility, scalability, adaption of conventional EEW algorithms for DAS, and potentia… [more]
