Thread: Earthquakes on DAS

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 base if our company gets appropriate credit.

Best Regards,
Björn Paulsson
