1. The impact of loading-induced stress variation on the seismicity of active faults
Abstract : Surface loads such as the ocean, atmosphere, and continental water, constantly modify the stress field of the Earth’s crust. Most earthquakes occur at tectonic plate boundaries and such stress perturbations on the active faults at the plate boundaries may trigger earthquakes. READ MORE

2. Seismicity Analyses Using Dense Network Data : Catalogue Statistics and Possible Foreshocks Investigated Using Empirical and Synthetic Data
Abstract : Precursors related to seismicity patterns are probably the most promising phenomena for short-term earthquake forecasting, although it remains unclear if such forecasting is possible. Foreshock activity has often been recorded but its possible use as indicator of coming larger events is still debated due to the limited number of unambiguously observed foreshocks. READ MORE

3. Mining induced seismicity in Sweden
Abstract : The virgin stress state in the rock mass is disturbed by mining, which leads to locally increased or decreased stresses. The rock mass in Sweden is generally composed of high strength brittle rock types, so the risk of seismicity and rockbursts (violent failures) increase with increasing depth of mining due to increasing stress levels.

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

5. Location and Relocation of Seismic Sources
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
