(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Abstract I document here an unknown letter from Charles F. Richter to Arthur Gutenberg addressing the development of the magnitude scales and Richter’s relationship to Beno Gutenberg. Added to the letter are a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The Barents Shear Margin separates the Svalbard and Barents Sea from the North Atlantic. During the break-up of the North Atlantic the plate tectonic configuration was characterized by sequential dextral shear, extension, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Transform margins are first‐order tectonic features that accommodate oceanic spreading. Uncertainties remain about their evolution, genetic relationship to oceanic spreading, and general structural character. When the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The global paleointensity database for 65–200 Ma was analyzed using a modified suite of paleointensity quality criteria (QPI) such that the likely reliability of measurements is assessed objectively and as consistently as ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In recent years, water shortage is becoming one of the most serious problems in the Poyang Lake. In this paper, the long-term water balance items of the Poyang Lake have been analyzed to reveal the coupling effects of Three ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The identification and measurement of ground deformations in urban areas is of great importance for determining the vulnerable parts of the cities that are prone to geohazards, which is a crucial element of both sustainable ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We present the description of an observation of a fireball recorded during the sunrise on July 15, 2021. Atmospheric trajectory, impact area, and heliocentric orbit were determined on the basis of three instrumental video ...

-
(Doctoral thesis / Doktoravhandling, 2018)Rock salt creeps under shear at the low temperatures encountered close to the surface. Salt flow is problematic for any cavity, like caverns or wells, because of the time dependent closure it induces if the internal hole ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Raman elastic thermobarometry has recently been applied in many petrological studies to recover the pressure and temperature (P–T) conditions of mineral inclusion entrapment. Existing modelling methods in petrology either ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We present an analytical solution based on the series expansion of Papkovich-Boussinesq's displacement potentials to derive the elastic solution of a spherical inclusion containing an eigenstrain or pressurized cavity in ...
-
(Master thesis / Masteroppgave, 2006)The study area of this work belongs to continental margin offshore Angola. Despite the large amount of data acquired, the geometries of subsalt sedimentary layers and lower crustal structure offshore Angola remain much ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The tectonic setting and mechanisms and duration of emplacement of Proterozoic massif-type anorthosites and the significance of typically associated ultrahigh-temperature (UHT) host rocks have been debated for decades. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Uncovering anthropogenic and environmental drivers behind past biological change requires integrated analyses of long-term records from a diversity of disciplines. We applied an interdisciplinary approach exploring effects ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Hazardous substances entering the sea, and ultimately deposited in bottom sediments, pose a growing threat to marine ecosystems. The present study characterized two coastal areas exposed to significant anthropogenic impact ...
-
(Master thesis / Masteroppgave, 2010)Abstract This study describes the contribution of anthropogenic factors for groundwater pollution in the urban environment of developing countries. Dire Dawa is one of the oldest urbanized and densely populated city in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The climatic and environmental impact of exclusively volcanic CO2 emissions is assessed during the main effusive phase of the Central Atlantic Magmatic Province (CAMP), which is synchronous with the end-Triassic mass ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Abstract. This study investigates the tectonostratigraphy and metamorphic and tectonic evolution of the Caledonian Reisa Nappe Complex (RNC; from bottom to top: Vaddas, Kåfjord, and Nordmannvik nappes) in northern Troms, ...
-
(Doctoral thesis / Doktoravhandling, 2021)Carbon capture and storage is a climate change mitigation technology that can help limit global warming. Monitoring strategies are put into place to inform on the fate of the injected CO2. Noble gases can play an important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Surface effects on deep-water gravity waves are investigated theoretically by the application of a Robin boundary condition with a complex Robin parameter, R=Rr+iRi. The Robin condition combines the shear stress and the ...
