  2. 6. Time-lapse Analysis of Borehole and Surface Seismic Data, and Reservoir Characterization of the Ketzin CO2 Storage Site, Germany

    Author : Can Yang; Christopher Juhlin; Rob Arts; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amplitude anomaly; AVO analysis; Carbon dioxide storage; Moving source profile survey; Reflection coefficient; Reservoir characterization; Static correction; Time-lapse analysis; Geophysics with specialization in Seismology; Geofysik med inriktning mot seismologi;

    Abstract : The CO2SINK (and CO2MAN) project is the first onshore CO2 storage project in Europe. The research site is located near the town of Ketzin, close to Potsdam in Germany. Injection started in June 2008, with a planned injection target of 100,000 tonnes of CO2. READ MORE

    Abstract : This dissertation is a comprehensive summary of four papers on the development and application of new strategies for locating tremor and relocating events in earthquake catalogs.In the first paper, two new strategies for relocating events in a catalog are introduced. READ MORE

  5. 8. Investigating Time-Varying Processes Using Seismicity and Time-Dependent Tomography

    Author : Alex Hobé; Ari Tryggvason; Olafur Gudmundsson; Roland Roberts; Nicholas Rawlinson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Time-Dependent Tomography; Joint Inversion; Geothermal Energy; Volcanotectonics; Seismic Unrest; Fagradalsfjall Eruption; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : Our global society is affected by, and makes use of, many time-varying processes. Processes related to geothermal energy and CO2 sequestration can help mitigate climate change and reduce the number of premature deaths (millions annually) due to air pollution from fossil fuels.

  6. 9. Seismological Investigation of Katla Volcanic System (Iceland) : 3D Velocity Structure and Overall Seismicity Pattern

    Author : Zeinab Jeddi; Ari Tryggvason; Olafur Gudmundsson; Heidi Soosalu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volcano tomography; volcano seismicity; Katla volcano; Earthquake location; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : The work in this thesis concentrates on Katla volcano in southern Iceland. This is one of Europe’s most active volcanoes and its history tells us that it poses many threats to society, both locally (Iceland) and on a broader scale (Europe). READ MORE

  7. 10. 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
