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.

Earthquakes on DAS
2022-10-06 16:06:05
Dear Sir/Madam, We published the attached paper last week. We have recorded more than 50 earthquakes on our 6,000 ft long vertical DAS array with about 2,500 Enhanced Rayleigh Scattering Seismic Sensors (ERSSS)(tm) - also known as DAS or Enhanced DAS (EDAS). In particular see slides 11 - 14 in the attached. We recorded the Fukushima M7.3 earthquake on March 16, 2022. See slide 11 and 12. The frequency content in our data is 4X of the USGS data. We are happy to contribute this data to your data… [more]
