Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling
(Journal article; Peer reviewed, 2020)Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ... -
Seismic hazard in Norway due to large earthquakes
(Master thesis, 2015-06-01)There are many faults located in Norway, posing as potential earthquake sources. Even though the seismicity is characterized as low to moderate, earthquakes of magnitude 3.5 or lower occur regularly. The seismic hazard ... -
Seismic hazard of the Izmir region, Turkey, based on a probabilistic seismic hazard assessment and stochastic ground motion simulations
(Master thesis, 2015-06-01)The purpose of this thesis is to conduct a seismic hazard analysis of the region surrounding Izmir. The chosen area is located in a very active seismic region with a high seismicity due to large amount of earthquakes. In ... -
Seismic Interpretation and Basin Modeling of the Svalbard Margin and Knipovich Ridge
(Master thesis, 2014-12-11)The Knipovich Ridge is a 550km long system situated on the seafloor west of Svalbard in the Northern Atlantic Ocean. It is a relatively young divergent boundary and ridge in the Northern Mid-Atlantic Ridge system. It is ... -
Seismic Modeling for Geothermal Reservoir Characterization
(Master thesis, 2016-05-31)The world's energy demand is increasing and there is a need for alternative energy sources to replace depleting fossil fuels. Geothermal energy could be an important part of these new sources of energy. For efficient and ... -
Seismic modeling of plaster models deformed in extension and contraction
(Master thesis, 2014-11-18)The effects of overburden, burial depth, source-receiver distance and frequency on seismic resolution have been studied in this thesis. Synthetic seismic sections of two plaster models, where a volume of plaster has been ... -
Seismic modelling and deconvolution of prestack depth migrated images through ray-based Point-Spread Functions
(Doctoral thesis, 2021-12-15)Seismic modelling involves simulating the propagation of waves through an Earth model to retrieve information about the subsurface. If an a priori Earth model is known, seismic modelling allows geoscientists to assess how ... -
Seismic modelling of the stratigraphic architecture of syn-rift deep-water channel complexes in the Corinth Rift, Greece
(Master thesis, 2022-08-03)Deep-water systems in rift basins lack extensive research because they tend to be buried in the subsurface making them hard to study directly. Rare, exhumed deep-water syn-rift depositional systems can therefore provide ... -
Seismic on floating ice: data acquisition versus flexural wave noise
(Journal article; Peer reviewed, 2019)Geophysical surveying of the Arctic will become increasingly important in future prospecting and monitoring of the terrestrial and adjacent areas in this hemisphere. Seismic data acquired on floating ice are hampered with ... -
Seismic properties of carbonate rocks with emphasis on effects of the pore structure
(Doctoral thesis, 2007-06-18) -
Seismic reservoir and source-rock analysis using inverse rock-physics modeling: A Norwegian Sea demonstration
(Peer reviewed; Journal article, 2015-11)Identifying type of rocks and fluids from seismic-amplitude anomalies can be challenging because of seismic nonuniqueness and rock-physics ambiguities. Lithology and fluid predictions based on seismic properties therefore ... -
Seismic signatures of siliciclastic reservoirs as function of burial history - a Barents Sea example.
(Master thesis, 2017-06-27)The Barents Sea is one of the most exciting areas regarding oil and gas exploration at the Norwegian Continental Shelf. Compared to the North Sea the area has a complex burial history, making the exploration challenging. ... -
Seismicity and Crustal Structure in North Greenland
(Master thesis, 2018-06-20)The crustal structure of Greenland varies greatly across the island. Previous studies have revealed that the region of North Greenland differs from the rest of Greenland, with a more shallow crustal thickness. Although ... -
Seismicity in Pakistan during 2008 and Local Site Response in Muzaffarabad and Islamabad, Pakistan
(Master thesis, 2009-06-02)Pakistan is tectonically significant and thus needs to be studied. In recent years, Pakistan is growing economically and the population has increased. Pakistan has experienced several disastrous earthquakes in the historical ... -
Seismicity modulation due to hydrological loading in a stable continental region: A case study from the Jektvik swarm sequence in Northern Norway
(Journal article; Peer reviewed, 2023)Seismic swarms have been observed for more than 40 yr along the coast of Nordland, Northern Norway. However, the detailed spatio-temporal evolution and mechanisms of these swarms have not yet been resolved due to the ... -
Seismicity, Deformation, and Metamorphism in the Western Hellenic Subduction Zone: New Constraints From Tomography
(Peer reviewed; Journal article, 2018-02-23)The Western Hellenic Subduction Zone is characterized by a transition from oceanic to continental subduction. In the southern oceanic portion of the system, abundant seismicity reaches depths of 100 km to 190 km, while the ... -
Seismisk studie av sedimentære prosesser og avsetningsmiljø på Vemafeltet, midtnorsk kontinentalmargin
(Master thesis, 2011-12-09)Denne oppgaven tar for seg havbunnsstrukturer og underliggende linser i Vemafeltet på nordlig del av Vøringplatået. Hovedfokus er på Naustformasjonen som er avsatt i pliocene- pleistocen tid, siden det er innen denne enheten ... -
Seismiske bølger i havis
(Master thesis, 2015-03-23)Seismiske innsamlinger på havis gir under gitte forhold opphav til kildeinduserte fleksurbølger, og dette problemet oppstår når seismisk energi blir fanget mellom grenseflatene is-luft og is-vann. Fleksurbølgen kan ...
