    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

  3. 22. Storied lines : using historical documentation to characterize archaeological connectivity

    Författare :Gísli Pálsson; Philip I. Buckland; Carl Knappett; Sören Sindbæk; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; archaeology; iceland; history; 18th century; network analysis; postgis; cidoc-crm; assemblage theory; archaeoinformatics; network;

    Sammanfattning : As the title suggests, this thesis applies historical documentation as a connective tissue to link together the main conceptual classes in Iceland’s largest SMR, Ísleif. These are the roughly 6000 historic farmsteads used as a classification scheme in Johnsen’s 1847 land census Jarðatal Johnsens. This thesis has three main components. LÄS MER

  7. 25. Toward fully automatic earthquake detection and processing for tomography in the Hengill area

    Författare :Frederic Wagner; Ari Tryggvason; Ólafur Gudmundsson; Roland Roberts; Steven Gibbons; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earthquake detection; local-earthquake tomography; Iceland; induced seismicity; geothermal activity; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    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.
