Upgrading the Liubeshka Station of the Ukrainian National Seismic Network: Modernization and Integration

Description: 

Understanding the geological and tectonic conditions of the territory of Ukraine in sufficient detail requires improvements of the regional earthquake monitoring capabilities through upgraded and new stations. Western, southwestern, and southern Ukraine lie within a seismically active belt formed by the Eurasian-African plate collision. This belt spans from the Azores through the Mediterranean, Black Sea, Caucasus, and Hindu Kush, including the Carpathian Arc with Vrancea subcrustal quakes and the Crimean-Black Sea region. In Ukraine's Carpathian region, the infrastructure for the Liubeshka (LUBU) station of the Ukrainian National Seismic Network (network code UT) has been upgraded and modernized as part of a network-wide improvement project.

The LUBU station, previously equipped with SM3 Soviet-era sensors, required significant enhancements. Key preparatory stages for installing new equipment at this site included: analysis of available satellite imagery to assess distances to potential noise sources, as well as a study of geological and tectonic conditions; site reconnaissance, including noise surveys and PPSD analysis; seismic profiling using a hammer source, which revealed details about the upper geological structure; drilling and construction of the necessary infrastructure. In December 2024, a new Trillium Slim posthole seismometer was installed. The configuration of data collection systems and transmission to the main server has been completed, along with integration into the EarthScope network for data exchange.

The modernization and expansion of Ukraine’s national seismic network is currently underway, with a focus on deploying permanent posthole broadband seismic stations for uniform coverage. This progress is supported by the US Department of Energy’s Seismic Cooperation Program and facilitated by the Science Technology Сenter of Ukraine. This partnership includes the Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine, Lawrence Livermore National Laboratory (USA), Michigan State University (USA), and EarthScope Consortium (USA).
