Infralyddeteksjon av snøskred og vurdering av konsept for automatisk integrasjon med database for snøobservasjoner
Lunde, Sondre (Master thesis, 2017)Infralydsystemene som er installert for overvåking av skredaktivitet i Norge har det kommersielle navnet «Infrasound detection of avalanches», forkortet IDA. I Norge har det tradisjonelt sett vært liten bruk av tekniske ... -
Integrated analysis of past, and potential future rock slope failures of various size from Rombakstøtta, Nordland
Morken, Odd André (Master thesis, 2017)Catastrophic failure of large rock slopes has led to fatalities in Norwegian settlements several times per century. The Geological Survey of Norway (NGU) currently carry out systematic geological mapping of potentially ... -
A Landform Evolution Model for the Mannen Area in Romsdal Valley, Norway
Hilger, Paula; Hermanns, Reginald; Etzelmüller, Bernd (Chapter, 2020)The Quaternary geology of western Norway’s landscape is the result of glacial and post-glacial sedimentation and erosional processes, a significant sea-level drop and high rock-slope failure activity. All these processes ... -
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 ... -
