Abstract
As of February 2022, when Russia initiated its invasion, the seismic network of the Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine (IGPH) was already in urgent need of modernization due to outdated and non-standard equipment. Today, IGPH is actively working to upgrade the network to meet international standards, enhance collaboration, and improve seismic hazard assessment. This effort is supported by the ORFEUS Data Integration Grant under the Geo-INQUIRE project, along with equipment donations from GFZ Helmholtz Centre for Geosciences, Gaiacode, and Universite Cote d’Azur. In 2024 and early 2025, five state-of-the-art seismic stations were deployed at existing sites. To assess seismic noise, probabilistic power spectral densities were analyzed. The upgraded stations in the Carpathian region show strong performance with noise levels matching expectations for their locations. Several upgraded stations (MEZ, RAKU, KSV) have already been integrated into the AdriaArray dataset. This collaboration strengthens regional seismic monitoring capabilities and enables the Ukrainian seismic network to contribute to international studies of tectonic processes. Data from upgraded stations are transmitted in real-time to IGPH’s data center and to the National Institute for Earth Physics (NIEP, Romania), where they are made publicly available under a CC-BY 4.0 license.
