Integrating DAS Seismic Data into the National Earthquake Monitoring at the Swiss Seismological Service

We explore the integration of Distributed Acoustic Sensing (DAS) seismic data into the standard processing system used by the Swiss Seismological Service (SED) for national monitoring. Using temporary DAS deployments across Switzerland, we have incorporated DAS data in the existing monitoring infrastructure based on SeisComP to enhance the accuracy and efficiency of seismic monitoring across the Swiss national network. Our approach is based on spatial and temporal decimation and the conversion of native data into strain and velocity data in miniseed format with associated metadata in FDSN station-XML format ready for integration alongside existing seismic data in SeisComP. We will present examples of standard manual event analyses, demonstrating how DAS data can be effectively used alongside traditional seismic data. We discuss our approach for DAS channels for picking, locating and magnitude estimation. These examples will demonstrate the improved resolution capabilities offered by DAS technology. Additionally, we will discuss the results of real-time processing tests that include both DAS data and traditional data from the Swiss national network. The presentation will conclude with a discussion of the challenges encountered during the integration process and future steps for further improving the use of DAS technology in seismic monitoring, with a view towards EEW.
