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 ... -
Seismo-tectonics around Lhasa, Tibet
(Master thesis, 2011-05-18)In this thesis I have described the seismic-tectonics of the Tibetan Plateau and around Lhasa as well as introduced the basic situation of seismic stations in Tibet. The focal mechanism, seismic moment and the source depth ... -
Seismo-Tectonics of the Alborz Mountains from the analysis of local earthquake data
(Master thesis, 2015-01-26)The Alborz range is part of the Alpine- Himalayan Orogenic belt, located in northern Iran, between the South Caspian block and the Central Iranian Block. In this thesis I have chosen an area in Alborz range which has ... -
Seismostratigrafi av glasiale og postglasiale sedimenter i innsjøen Bolshoye Shchuchye, Polar Ural, Russland
(Master thesis, 2017-08-31)I denne masteroppgaven har målet vært å kartlegge og undersøke avsetningen i innsjøen Bolshoye Shchuchye ved bruk av seismisk data. Dette gir et innblikk i hvordan sedimentasjonsforholdene i denne arktiske innsjøen reflekterer ... -
Seismotectonics in Central Sudan and Local Site Effects in Western Khartoum
(Master thesis, 2008-03-27)The central part of Sudan is tectonically significant and thus needs to be studied. In recent years, the central part has grown economically and the population has increased. This results in growing interest to estimate ... -
The seismotectonics of western Skagerrak
(Peer reviewed; Journal article, 2011-04-20)The seismically active Skagerrak region in the border area between Denmark and Norway has traditionally been associated with uncertain earthquake locations due to the limited station coverage in the region. A new seismic ... -
Sekvensstratigrafisk og paleogeografisk studie av nedre tidlig tortonske avsetninger i Agua Amargabassenget i Syd-Spania
(Master thesis, 2014-06-01)Den romlige og stratigrafiske fordeling av de eldste tidlig tortonske avsetningene i Agua Amargabassenget i Sydøst-Spania er kartlagt for å bestemme bassengets paleogeografiske og sekvensstratigrafiske utvikling. Disse ... -
Semi‐automatic Ice Rafted Debris quantification with Computed Tomography
(Journal article; Peer reviewed, 2021)Sedimentary ice-rafted debris (IRD) provides critical information about the climate sensitivity and dynamics of ice sheets. In recent decades, high-resolution investigations have revelated ice rafting events in response ... -
Sen weichsel foraminiferstratigrafi i Norskerenna; paleomiljø og sedimentgenese
(Master thesis, 2015-06-01)Sammendrag For å få bedre kunnskap om oseanografiske endringer, sedimentasjonsmiljø og klima er kjerne GS12-172-04PC, lokalisert i sørlige delen av Norskerenna nær Lista, undersøkt med vekt på bentiske foraminifera. For å ... -
Sen-holocene maringeologiske avsetningsprosesser i Førdefjorden
(Master thesis, 2022-06-01)Fjordlandskapet langs den vestnorske kysten er viktige maringeologiske arkiv grunnet deres semi-isolerte morfologi. Fjordbassengenes sedimentære avsetninger består hovedsakelig av sediment knyttet til proksimale- og distale ... -
Sen-weichsel og tidlig holosen strandforskyvning i Os-området, Hordaland
(Master thesis, 2000)Late Weichselian and Early Holocene relative sea-level changes in four isolation basins in the Os area, Hordaland (Western Norway) were studied using both bio- and lithostratigraphical methods. Isolation and ingression ... -
Senglasiale vulkanske askelag i innsjøsedimenter på Vestlandet
