The strongest in Western Carpathians (WC) in XXI century M5 earthquake occurred on 9 October 2023 near Humenne (Slovakia). It was widely felt in Slovakia and Poland, what is rare. It occurred in complex tectonic setting formed with overthrusted frontal nappes and rotated internal lithospheric units. The present tectonic regime of the WC is resulting with vertical movements related to convergence of the WC and of the stable Eur...

Poland is characterised by weak natural seismicity. However, the last analysis of the natural seismic hazard in the country was carried out 24 years ago. Therefore, a significant fraction of the recorded seismicity is not included in the hazard estimates currently used, either because recent observations are not taken into account or because of improved seismic network capabilities. Furthermore, Podhale, in the Tatra Mountains...

Reservoir-triggered seismic activity depends not only on the technical characteristics of the future reservoir (filling volume, the height of water column) but also on the seismo-tectonics and the natural seismic processes occurring in the area before construction of an artificial reservoir. Passive seismic monitoring was realised near Lai Chau (Vietnam) before the impoundment started. It allowed exploration of the natural sei...
