Processing and analysis of seismic and microseismic data recorded at the Yangibozor Experimental Research Observatory in 2021–2025 using the Geopsy software

This paper presents the processing and analysis of microseismic data recorded at the Yangibozor Experimental Research Observatory during 2021-2025 using the HVSR method implemented in the Geopsy software. The temporal variations in the resonance frequency (Fo) and maximum spectral amplitude (Ao) were analyzed. The results of five years of observations were compared to assess seasonal and annual variations in the microseismic background. The results indicate that the dynamic properties of the ground remained relatively stable over the long-term observation period. The increases in amplitude observed during certain periods can be attributed to enhanced microseismic activity caused by natural and anthropogenic factors. The findings confirm the effectiveness of the Geopsy software as a tool for microseismic monitoring.
