1. Location and Relocation of Seismic Sources
Sammanfattning : 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. LÄS MER
2. Seismicity and crustal structure in Iceland
Sammanfattning : The main goal of this Ph.D. thesis is to improve locations of earthquake hypocenters and to resolve heterogeneous crustal structure and its effects on travel times. The data and case studies are drawn from the Icelandic national SIL network and the temporary NICE project deploy-ment in the Tjörnes Fracture Zone. LÄS MER
3. Toward fully automatic earthquake detection and processing for tomography in the Hengill area
Sammanfattning : This thesis focuses on the automation of seismic data analysis, in particular, event detection, quality assessment of detected events, and preparation of an earthquake catalogue for seismic tomography.The developed event detector uses back-propagation and stacking of a seismic trace attribute with a known velocity model to detect and locate events.

4. Seismotectonics and lithospheric structure of Costa Rica
Sammanfattning : The interaction of different tectonic features on a short-distance scale of 100's of km produces the complexity of the Costa Rica region. The intraplate Caribbean earthquake activity of shallow-depth nature is mainly concentrated along an E-W axis in the central part of the country. LÄS MER
