Risk assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI) - Euro-Japan collaboration
Harbitz, Carl Bonnevie; Nakamura, Y.; Arikawa, T.; Baykal, C.; Dogan, G.G.; Frauenfelder, Regula; Glimsdal, Sylfest; Guler, H.G.; Issler, Dieter; Kaiser, Gunilla; Kânoǧlu, U.; Kisacik, D.; Kortenhaus, A.; Løvholt, Finn; Maruyama, Y.; Sassa, S.; Sharghivand, N.; Strusinska-Correia, A.; Tarakcloglu, G.O.; Yalciner, A.C. (Journal article, 2016)The 2011 Tōhoku event showed the massive destruction potential of tsunamis. The Euro-Japan “Risk assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI)” project aimed at using ... -
Ryggfonn - Options for reconstruction of the test site. Deliverable of the NFR-Snow research programme SIP-6
Issler, Dieter (NGI-rapport;58120-34, Research report, 2001-01-31)Norges Forskningsråd (NFR) -
Seismic location and tracking of snow avalanches and slush flows on Mt. Fuji, Japan
Pérez-Guillén, Cristina; Tsunematsu, Kae; Nishimura, Kouichi; Issler, Dieter (Peer reviewed; Journal article, 2019)Avalanches are often released at the dormant stratovolcano Mt. Fuji, which is the highest mountain of Japan (3776 m a.s.l.). These avalanches exhibit different flow types from dry-snow avalanches in winter to slush flows ... -
A Simple Model for the Variability of Release Area Size
Issler, Dieter (NGI-Rapport;20200017‐03‐TN, Research report, 2023-08-24)The hazard mapping tool NAKSIN estimates the release probability of potential release areas (PRAs) by testing a stability criterion based on the infinite-slope approximation with a large sample of synthetic weather situations. ... -
Snøskyskredmodell SL-1D – Grunnleggende ligninger og korrektur-faktorer
Issler, Dieter (NGI-rapport;20170131-06-TN, Research report, 2017-12-22)For tiden mangler det en beregningsmodell for snøskyskred som er like raskt og enkelt å bruke som f.eks. modellene RAMMS eller MoT-Voellmy for den tette delen av snøskred. I rådgivningsoppdrag brukes det derfor av og til ... -

Studies on the snow avalanche dynamics by the full-scale experiments
Nishimura, K.; Pérez-Guillén, Cristina; Ito, Yoichi; Yamaguchi, Satoru; Saito, Yoshihiko; Issler, Dieter; Fischer, Jan-Thomas (Lecture, 2018)Systematic full-scale but small avalanche experiments have been started since 2016 in Niseko, a ski resort in Hokkaido, Japan. Although the vertical drop in the test sites are 100 to 200 m, they have advantages that we are ... -
The 2017 rigopiano avalanche—dynamics inferred from field observations
Issler, Dieter (Peer reviewed; Journal article, 2020)This note first summarizes the history of the manuscript “On a Continuum Model for Avalanche Flow and Its Simplified Variants” by Grigorian and Ostroumov—published in this Special Issue—since the early 1990s and explains ... -
The upgraded full-scale avalanche test-site Ryggfonn, Norway.
Gauer, Peter; Breien, Hedda; Issler, Dieter; Kristensen, Krister; Kronholm, Kalle; Lied, Erik; Lied, Karstein (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)Measurements of full-scale avalanches are expensive and time consuming, but are indispensable to gain in-depth understanding of the flow behavior of avalanches. They are needed to crosscheck the scaling used in small-scale ... -
Vulnerability of houses and persons under avalanche impact – the avalanche at Longyearbyen on 2015-12-19
Issler, Dieter; Jónsson, Árni; Gauer, Peter; Domaas, Ulrik (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2016)This study uses data from the avalanche that killed two persons and destroyed eleven essentially identical wood-frame houses in Longyearbyen, Svalbard, on 2015-12-19. The avalanche is back-calculated with a dynamical model ...
