1. Studies of Unusual Seismicity and Long Period Events at the Glacier Overlain Katla Volcano, Iceland
Abstract : 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. READ MORE

2. Seismic imaging of deep crustal reflectivity in Sweden and Iceland
Abstract : Seismic reflection profiling, originally developed by the petroleum industry, was adapted to systematic imaging of deep structures some 25 years ago. In continental areas, these measurements often show weakly reflective upper crust and strongly reflective lower crust. READ MORE

3. Prediction of Strong Ground Motion and Hazard Uncertainties
Abstract : The purpose of this thesis is to provide a detailed description of recent methods and scientific basis for characterizing earthquake sources within a certain region with distinct tectonic environments. The focus will be on those characteristics that are most significant to the ground-shaking hazard and on how we can incorporate our current knowledge into hazard analyses for engineering design purposes.

4. 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

5. Simulating Earthquake Rupture and Near-Fault Fracture Response
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
