Liquiñe‑Ofqui’s fast slipping intra‑volcanic arc crustal faulting above the subducted Chile Ridge
De Pascale, Gregory P; Froude, Melanie; Penna, Ivanna; Hermanns, Reginald; Sepulveda, Sergio A; Moncada, Daniel; Persisco, Mario; Easton, Gabriel; Villalobos, Angelo; Gutiérrez, Francisco (Peer reviewed; Journal article, 2021)The southernmost portion of the Liquiñe-Ofqui fault zone (LOFZ) lies within the proposed slab window which formed due to oblique subduction of the Chile Ridge in Patagonia. Mapping of paleo-surface ruptures, offsets, and ... -
Past slope collapse and current unstable slopes along a cliff at Hyllestad Kommune
Nes, Vegard (Master thesis, 2018)With the aim of a complete national database of potential unstable slopes, the Geological Survey of Norway currently carries out systematic geological mapping of rock slopes organized in counties. As part of the survey of ... -
Permafrost controls the displacement rates of large unstable rock-slopes in subarctic environments
Penna, Ivanna; Magnin, Florence; Nicolet, Pierrick; Etzelmüller, Bernd; Hermanns, Reginald; Böhme, Martina; Kristensen, Lene; Noel, Francois; Bredal, Marie Bergvik; Dehls, John F. (Peer reviewed; Journal article, 2022)Determining the link between permafrost and the displacement rates of large unstable rock-slopes (LURSs) is fundamental for understanding future hazard scenarios and establishing appropriate management strategies. From an ... -
Semi-empirical prediction of dam height and stability of dams formed by rock slope failures in Norway
Oppikofer, Thierry; Hermanns, Reginald; Jakobsen, Vegard Utstøl; Böhme, Martina; Nicolet, Pierrick; Penna, Ivanna (Peer reviewed; Journal article, 2020)Based on an inventory of 69 dams formed by rock slope failures in southwestern Norway and published inventories from other parts of the world, we developed semi-empirical relationships linking the maximum dam height (HD.max ... -
Structural and lithological controls on Quaternary rock slope failures in the interior of the Devonian Hornelen basin, western Norway
Feldmann, Martin Valand (Master thesis, 2021)Flyfoto avslører en stor konsentrasjon av steinsprang og fjellskredavsetninger på Hennøy halvøya, tilhørende den indre delen av Hornelen devonbasseng i Vestland fylke. Øst for Svelgen bysentrum ligger Svelgsegga, hvor flere ...
