1. 1. Induced Seismicity in the Dannemora Mine, Sweden

   Master-uppsats, Uppsala universitet/Geofysik

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

   Sammanfattning : 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.

3. 2. One- and Three-dimensional P- and S-wave Velocity Models of Central and Southern Sweden Based on SNSN Data

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Ne Xun Chan; [2014]
   Nyckelord :Seismic tomography; seismicity; local earthquake tomography; Sweden; seismic network;

   Sammanfattning : The velocity structures of southern and central part of Sweden have been derived with the local tomography (LET) method. The region has been divided into two study areas and the datasets come from the P- and S-wave traveltimes recorded by the Swedish National Seismic Network (SNSN). LÄS MER
