ANALYSIS OF GNSS STATION SRJV00BIH AND SEISMIC ACTIVITY

<p>This paper deals with the analysis of the time series of GNSS coordinates from station SRJV00BIH and their connection with seismic activity along key faults in Bosnia and Herzegovina. By using data on a time series of GNSS coordinates, the possibility of detecting tectonic movements in the context of specific earthquakes that occurred on a certain day was investigated. This seismic activity is linked to the data collected from the GNSS station. This involves the interaction of GNSS data with seismic events of intermediate magnitudes to identify potential deformations accompanying an earthquake. Monitoring these data revealed whether there was a movement of the ground or deformations during the period of the earthquake. The methodology includes using the TSAnalyzer tool to analyse long-term trends and use of the Heaviside function, thereby identifying fluctuations potentially related to seismic activity. The results showed certain patterns in coordinate changes that coincide with seismic events on faults in the region, which suggests that GNSS stations can serve as an additional tool for monitoring geodynamic phenomena and improving the precision of seismic monitoring. Further research is proposed to improve the detection accuracy and integration of GNSS networks into regional early warning systems. The study aims to determine to what extent terrain deformations that precede significant seismic events can be detected and how GNSS data can help better understand fault activity.</p>
