posted on 2021-01-04, 17:09 authored by Lars Olsen, Odleiv Olesen, Fredrik Høgaas, Georgios TassisBased on trenching transverse to the fault scarp, observation of sediments and structures, and 14C-dating of buried organic material, we conclude that the Stuoragurra fault event, accompanied with earthquake of magnitude 7 at Máze (Masi) occurred just before or during the Little Ice Age (LIA, c. 1500-1920 AD).
A compilation of data collected during fieldwork along the fault complex, and subsequent analyses and interpretations, including georadar profiling and preliminary bothanical studies, are in progress (Olsen et al., in prep.).
