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.

Hi All, A M8.2 earthquake occurred in Alaska today. There is a submarine fiber optic cable with several landing points in the area, shown in the map below. This could be a great opportunity for this DAS RCN community to quickly instrument some of these cables with DAS to monitor aftershocks and to hopfeully catch a M7-ish aftershock. That would be the first time a subduction aftershock sequence is recorded by a rapid DAS deployment. The owner of the cable is GCI (https://www.gci.com/). … [more]
