Abstract The article presents an overview of the central part of a new broadband transportable array on the East European craton (EEC). The main goal of the array is to study the region’s lithospheric structure using passive seismic techniques such as the receiver function. The first stage of the experiment involved installing eight new broadband stations alongside four permanent ones in the central part of the EEC, which is a Paleoproterozoic collision zone. The application of the receiver function method to three long-operating stations in the central part of the EEC revealed significant Moho topography. In addition, a mid-lithospheric discontinuity is identified in the upper mantle, with its depth and thickness varying significantly across the study region. Another objective in the deployment of the sensors is to monitor the seismicity of the region. The new seismic stations allow for detection of seismic events with magnitudes ML2.0. The stations of the array were the closest to an event that occurred on 18 March 2024, near the city of Rybinsk (58.37, 38.84). Analysis of the seismograms, incorporating data from other networks, made it possible to propose its genesis as an earthquake with ML 3.3.
