Abstract
In September–October 2024, an experiment on earthquake registration in the Kuril-Kamchatka subduction zone was conducted using the distributed acoustic sensing (DAS) method. The fiber-optic monitoring system is an independent system consisting of a fiber-optic amplitude vibroacoustic sensor and a fiber-optic cable. The fiber-optic line is deployed in the building of the Institute of Volcanology and Seismology in Petropavlovsk-Kamchatsky, with the cable securely attached to the building’s foundation to ensure coupling with the building’s structure. The DAS earthquake records were compared with the data from the IVS seismic station. Four tectonic earthquakes that occurred near Petropavlovsk-Kamchatsky were selected for the analysis. It is shown that DAS signals preserve the main features of seismograms, making them suitable for use in seismological kinematic tasks.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
