1. 1. Fluid-rock interaction in two seismically active areas : The Tjörnes Fracture Zone, northern Iceland and the Shillong Plateau, northeastern India

   Författare :Lillemor Claesson; Alasdair Skelton; Steven Ingebritsen; Stockholms universitet; []
   Nyckelord :Tjörnes Fracture Zone; Shillong Plateau; Iceland; India; hydrogeochemical monitoring; earthquakes; geothermal; transition metals; dissolution; basalt; feldspar weathering; source switching; Geology; geologi;

   Sammanfattning : Hydrogeochemical monitoring can improve our understanding of fluid-rock interaction, and may detect anomalies that are precursory to- or caused by- earthquakes. In this study, hydrogeochemical monitoring was carried out in two distinct tectonic settings, to study coupling between hydrogeochemical changes and seismic activity. LÄS MER

3. 2. Seismicity and crustal structure in Iceland

   Författare :Claudia Abril; Ólafur Gudmundsson; Vala Hjörleifsdóttir; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earthquake relocation; local earthquake tomography;

   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
