  1. 1. Crustal stress studies using microearthquakes and boreholes

    Författare :Björn Lund; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The state of stress in the crust is essential for the understanding of geodynamic processes such as the transmission of plate driving forces through the lithosphere and the triggering of earthquakes. This thesis describes the development and application of new methods for the estimation of crustal stresses. LÄS MER

  2. 2. Source analysis of multiplet earthquakes (two case studies in Iran)

    Författare :Samar Amini; Roland Roberts; Björn Lund; Zaher Hossein Shomali; Kuvvet Atakan; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Multiplet earthquakes; slip inversion; Coulomb stress; rupture directivity;

    Sammanfattning : Multiplet earthquakes are large earthquakes of similar magnitude which occur close in time in the same limited geographical area. They are not common but they considerably increase the potential hazard in the area in which they occur. LÄS MER

  3. 3. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

    Författare :Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
    Nyckelord :Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

    Sammanfattning : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Studies of Unusual Seismicity and Long Period Events at the Glacier Overlain Katla Volcano, Iceland

    Författare :Kristín Jónsdóttir; Roland Roberts; Björn Lund; Göran Ekström; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Geofysik; Geophysics Specialized In Seismology; geofysik; med inriktning mot seismologi;

    Sammanfattning : Earthquake catalogues are usually dominated by diffusive behaviour consistent with the Omori law of aftershocks. This is investigated in terms of waiting times, i.e. the time between successive events in a time-sorted earthquake catalogue. LÄS MER
