  1. 1. Seismic tomography : Algorithms and applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Zhengsheng Yao; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Geophysics Specialized In Seismology; geofysik; med inriktning mot seismologi;

    Abstract : A preferred algorithm for seismic tomography needs to have capabilities including computational efficiency, minimal computer memory requirements, easy regularization and nonuniqueness analysis. In this thesis, regularised recursive least squares for seismic tomography is developed. READ MORE

  2. 2. Statistical Seismology Studies in Central America b-value, seismic hazard and seismic quiescence

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : David Aníbal Monterroso Juárez; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; b-value; seismic hazard; Monte Carlo; seismic quiescence; Central America; stress; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Abstract : The present thesis collects results of research applying theory and methods of statistical seismology to the seismicity of Central America, a region with a complex tectonic setting controlled by the interaction of four major plates, namely the Caribbean, Cocos, Nazca and North American plates.Three different earthquake catalogues were used for studies focused on stress in a tectonic volume, seismic hazard maps and seismicity patterns (precursors), covering the region 94ºW to 81ºW and 5ºN to 20ºN.

    Abstract : An extensive multi-channel seismic dataset acquired between 1970 and 1990 by Oljeprospektering AB (OPAB) has recently been made available by the Geological Survey of Sweden (SGU). This thesis summarizes four papers, which utilize this largely unpublished dataset to improve our understanding of the geology and CO2 storage capacity of the Baltic and Hanö Bay basins in southern Sweden.

  4. 4. Geological development of the East African coastal basin of Tanzania

    University dissertation from Stockholm : Acta Universitatis Stockholmiensis

    Author : Samson Mpanda; Stockholms universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; seismic methods; seismic stratigraphy; multichannel seismic recordings; tectonic development; Karoo; Mesozoic; Tertiary; East Africa; Tanzania; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Abstract : The East African coastal basin of Tanzania, which is characterised by an extensional tectonic style, is located along the passive continental margin of the western Indian Ocean. The present study is concerned with the Mafia Island and the Mafia Channel which together form a subbasin within the north-south elongated coastal sedimentary basin of Tanzania. READ MORE
