Seismogenic faults in southern Peru

The Peruvian subduction zone is prone to destructive megathrust earthquakes that are the scope of scientific investigations from many years However, our knowledge on smaller crustal earthquakes in the overriding plate that, due to the shallow focal depth and proximity to the human settlements, can be equally hazardous, is significantly smaller

Tectonic activity of Sudetes recorded in the Niedźwiedzia Cave

Although the Sudetes are considered tectonically stable, research conducted in the Niedźwiedzia Cave in Kletno by dr Jacek Szczygieł, from our institute, indicates that at least 5 strong earthquakes (M>6) have occurred in the eastern Sudetes during the last 300 thousand years This record was reconstructed mainly thanks to radiometric dating

Early Devonian algae from the Holy Cross Mountains. 400 mln year old green algae from Poland

Filamentous algae, especially those without a calcareous skeleton, are very rarely preserved as fossils Consequently, their fossil record is discontinuous and very incomplete Current paleontological investigations of the Lower Devonian (400 Ma) rocks from the Bukowa Góra Quarry (Holy Cross Mountains; Poland) revealed vegetative remains of filamentous algae Individual cells were
