Shocks in a Box | Analoge Erdbeben & Seismische Zyklen

Experimentelle Simulation der seismotektonischen Deformation über Zeiträume von Erdbeben bis tektonischer Entwicklung.

Dieses Projekt wird realisiert in unserem Labor für Experimentelle Tektonik am GFZ Helmholtz-Zentrum für Geoforschung Potsdam (HelTek) sowie in unserem Partnerlabor an der Universität RomaTre (LET).
