  1. 6. Seismic activity and end- or post-glacial faults in northern Fennoscandia, focusing on Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Kie Oyama; [2016]
    Keywords : Fennoscandia; seismicity; end post-glacial fault; deglaciation; glacial uplift;

    Abstract : During the late or post Weichselian glacial periods, about 9500 years ago, several faulting associated with large scale earthquakes were triggered in northern Fennoscandia. The end- or post-glacial scarps have a range of the lengths c. 3 to 155 km and the heights 0 to 30 m while most of them are reverse faults trending NE-SW with SE dips. READ MORE

  3. 7. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Kim Torberntsson; Vidar Stiernström; [2016]
    Keywords : numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

    Abstract : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. READ MORE

  4. 8. Induced Seismicity in the Dannemora Mine, Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Joanna Holmgren; [2015]
    Keywords : Mining-induced seismicity; phase picking; particle motion; local earthquake tomography; correlation; local magnitude;

    Abstract : Induced seismicity is a common phenomenon that occurs as soon as the stress state in the subsurface is externally altered in a way that faults are destabilized. It is especially problematic in stable tectonic regions where the area is not used to earthquakes; the infrastructure is not built to withstand ground movement and thus when the induced seismicity occurs damage can follow.
