  2. 1. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Author : Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. READ MORE

  4. 2. Fast fault detection for power distribution systems

    Author : Magnus Öhrström; KTH; []
    Keywords : fast fault detection; power systems;

    Abstract : The main topic of this licentiate thesis is fast faultdetection. The thesis summaries the work performed in theproject“Fast fault detection for distributionsystems”.In the first chapters of the thesis the term“fast”is used in a general manner. READ MORE

  5. 3. Fluid-rock interaction in two seismically active areas : The Tjörnes Fracture Zone, northern Iceland and the Shillong Plateau, northeastern India

    Author : Lillemor Claesson; Alasdair Skelton; Steven Ingebritsen; Stockholms universitet; []
    Keywords : Tjörnes Fracture Zone; Shillong Plateau; Iceland; India; hydrogeochemical monitoring; earthquakes; geothermal; transition metals; dissolution; basalt; feldspar weathering; source switching; Geology; geologi;

    Abstract : Hydrogeochemical monitoring can improve our understanding of fluid-rock interaction, and may detect anomalies that are precursory to- or caused by- earthquakes. In this study, hydrogeochemical monitoring was carried out in two distinct tectonic settings, to study coupling between hydrogeochemical changes and seismic activity. READ MORE

  6. 4. Simulating Earthquake Rupture and Near-Fault Fracture Response

    Author : Billy Fälth; Björn Lund; Roland Roberts; Harald Hökmark; Eric Dunham; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. READ MORE

  7. 5. Interaction of Segments along Rifts that Separate Continents and Ridges that Spread Ocean Floors

    Author : Tatiana Tentler; Christopher Talbot; Olivier Dauteuil; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; extension; oceanic floor; rift; normal fault; segment; interaction; propagation; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : The face of the Earth is constantly renewed by continental rifts that open and allow ridges to spread oceanic floor. Both types of these linear extensional structures are morphologically and structurally segmented. This thesis aims to provide insights into the interaction of such segments as they propagate and mature. READ MORE
