Keywords: hardware-software system “Dunay”, distributed acoustic sensing, DAS, Global DAS Month, February 2023 earthquakes in Turkey, signal quality assessment, first arrivals picking
Аnnotation: In February 2023, the international experiment Global DAS Month was carried. A unique data set of more than 156 events with M ≥ 5 was collected by participants and recorded by different DAS systems deployed world-wide. The purpose of the experiments was to evaluate the feasibility of the global DAS system for teleseismic monitoring and to identify any bottlenecks that may arise. The article presents preliminary results of data anal-ysis obtained by T8 Sensor LLC, a Russian participant in the experiment. Some metrological characteristics of the applied observation system had been evaluated. The conducted study allows to compare DAS system with world analogues in the area of seismic monitoring and to map out a plan for the future works.
