  1. 1. Origin of Silicic Magmatism at the Katla Volcano, South Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Caroline Svanholm; [2021]
    Keywords : Katla volcano; Iceland; high-silica rocks; oxygen isotopes; AFC processes; Vulkanen Katla; Island; kiselrika bergarter; syreisotoper; AFC-processer;

    Abstract : Katla volcano, South Iceland, is a bimodal volcanic system hosting an unusual high number of silicic rocks within a basaltic rift setting. The petrogenesis of silica-rich rocks at Katla is controversial and two end-member hypotheses have been suggested. READ MORE

  3. 2. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Jonsdottir; [2018]
    Keywords : Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Abstract : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. READ MORE

  4. 3. 1992-1998 seismicity and deformation at Mt. Eyjafjallajökull volcano

    University essay from Lunds universitet/Geologiska institutionen

    Author : Malou Blomstrand Stinessen; [1999]
    Keywords : Island; Mt. Eyjafjallajökull volcano; deformation; seismicity; geology; geography; Earth and Environmental Sciences;

    Abstract : Sammanfattning: Målet med detta examensarbete i tillämpad geofysik är att öka förståelsen för geologiska och geofysiska processer och deras samspel under vulkanen Eyjafjallajökull i södra Island. På Island har sedan ett tiotal år tillbaka använts geodetiska mätningar med Global Positioning System (GPS) instrument och geodetiska tiltmätare för att påvisa krustal deformation, som orsakas av vulkanisk, annan magmatisk eller seismisk aktivitet.
