Shocks in a Box | Analogue Earthquakes & Seismic Cycles

Experimental simulation of seismotectonic deformation across time-scales ranging from earthquakes to tectonic evolution.

This project is realized in our Laboratory for Experimental Tectonics at the GFZ Helmholtz Centre for Geosciences Potsdam (HelTec) as well as in our partner lab at the University of RomaTre (LET).
