Cross-scale strain analysis in the Afar rift (East Africa) from automatic fault mapping and geodesy
Abstract. The formation of continental rift systems is characterised by the interplay of magmatic and tectonic processes. Their evolution involves a wide range of timescales, from centennial scales of...
