Mathematical modeling of dense avalanches
(NGI Publication;203, Chapter, 1998)The paper presents a brief overview of mathematical models for dense avalanches that were developed by researchers of Moscow State University. Examples of calculations for real avalanches in Caucasus and Khibiny Mountains ... -
Maximum frontal speeds, alpha angles and deposit volumes of flowing snow avalanches
(Peer reviewed; Journal article, 2018)Approximate maximum frontal speeds from 89 snow avalanches were analyzed to yield probabilistic estimates of maximum speed scaled with path length parameters. In addition to speeds, 88 companion values of runout for the ... -
Måleresultater etter fullskala sprengningsforsøk – hvor kraftige vibrasjoner tåler en bygning før det oppstår skader
(Conference object, 2019)Grenseverdier for sprengningsvibrasjoner fastsettes på grunnlag av NS 8141 Vibrasjoner og støt. Bergsprengning kan gi så kraftige vibrasjoner at det forårsaker skader på tilstøtende byggverk. Det er imidlertid sjelden at ... -
Måling av injeksjonsresultat med vanntapsmålinger i tunnel
(NGI-rapport;20200436-05-R, Research report, 2022-12-23)Forsøk ved Fornebubanens hovedtunnel har demonstrert at vanntapsmålinger ved stuff kan gjøres enkelt og effektivt, med bruk av lett utstyr. Vanntapsmålingene viser lavt vanntap og meget tett bergmasse etter 2-stegs injeksjon ... -
Måling av krefter på skredoverbygg
(NGI-rapport;75413 Notat 1975-09-01, Research report, 1975-09-01)Design loads on avalanche galleries are of great importance to know and unfortunately they can be extremely variable depending on conditions. In addition, values are difficult to determine and results of present experimental ... -
Measurement of avalanche speeds and forces: instrumentation and preliminary results of the Ryggfonn project.
(Journal article, 1985)The Ryggfonn project is a Full scale experiment carried out to investigate the impact of avalanches on structures and the effects of a retaining dam in the avalanche path. The vertical drop of the avalanche path is 910 m ... -
Metagenomics in CO2 Monitoring
(Journal article, 2013)Leakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying ... -
The meteorological condition for larger avalanches at Senjojiki Bowl in Japanese Central Alps
(NGI Publication;203, Chapter, 1998)The Senjojiki Bowl has a typical avalanche terrain consisting of8 avalanche tracks. During the last 25 years 16 alpinists and ropeway workers in total have been killed by avalanches. Since no reliable avalanche warning is ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
Microplastic in sediments and fauna. Offshore and inshore
(NGI Rapport;20210130-01-R, Report, 2022-01-31)Samples of sediment and sediment-dwelling organisms were obtained from the Norwegian Continental Shelf and fjords in Southern Norway. These are referred to as offshore areas and inshore areas, respectively. The sediments ... -
Microseismic monitoring and interpretation of injection data from the In Salah CO2 storage site (Krechba), Algeria
(Journal article, 2013)Microseismic data analysis together with interpretation of injection data at the In Salah CO2 storage site provides a valuable tool for improved understanding of the subsurface injection and storage processes. More than ... -
Middle Miocene tropical oligotrophic lagoon deposit sheds light on the origin of the Western Australian coral reef province
(Peer reviewed; Journal article, 2021) -
Mind the Gap: Towards a Typology of Climate Service Usability Gaps
(Peer reviewed; Journal article, 2020)Literature on climate services presents a large diversity of different services and uses. Many climate services have ‘usability gaps’: the information provided, or the way it is visualized, may be unsuitable for end users ... -
Model calibration: A hierarchical Bayesian approach

A model for frictional melt production beneath large rock avalanches
(Journal article, 2008)Two puzzling traits of giant rock avalanches (sturzstroms) are the decrease of the effective friction coefficient as a function of the volume (volume effect) and the remarkable preservation of large geological structures ... -
Modeling propagation and inundation of the 11 March 2011 Tohoku tsunami
(Journal article, 2012)On 11 March 2011 the Tohoku tsunami devastated the east coast of Japan, claiming thousands of casualties and destroying coastal settlements and infrastructure. In this paper tsunami generation, propagation, and inundation ... -
Modelling 2018 Anak Krakatoa Flank Collapse and Tsunami: Effect of Landslide Failure Mechanism and Dynamics on Tsunami Generation
(Peer reviewed; Journal article, 2020)The 2018 Anak Krakatoa volcano flank collapse generated a tsunami that impacted the Sunda Strait coastlines. In the absence of a tsunami early warning system, it caused several hundred fatalities. There are ongoing discussions ... -
Modelling creep behaviour of anisotropic soft soils
(Journal article, 2015)This paper presents a three dimensional constitutive model that describes the creep behaviour of natural clays with anisotropic stress–strain response, focussing on robust model implementation. Creep is formulated using ... -
