  1. 1. The future of geothermal energy in Europe

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Susana Barquín del Rosario; [2022]
    Nyckelord :Geothermal Energy; Opportunities; Risks; Barriers; Development scenarios; Status in Europe; Potential;

    Sammanfattning : In this paper it is investigated the role that geothermal energy could play in theenergy mix, to meet new system requirements. As any other source, geothermal energy harnessing implies a number of risksmainly related to induced seismicity and landslides, together with the releaseof as greenhouse gases and metal salts.

  2. 2. Preprocessing of earthquake tremor data for tremor location

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Brian Rydgren; [2022]
    Nyckelord :Tremor; Earthquake; Volcano;

    Sammanfattning : When analysing volcanic seismicity and volcanic events, it is often interesting to focus on tremor, which is a signal of long duration. This is because not much is known about tremor. Unlike earthquakes, sources of tremor are difficult to locate due to them not having any clear onsets in the seismic signal. LÄS MER

  3. 3. Study of Production Drifts Stability and Assessment of Reinforcement Requirements at LKAB Konsuln Test-Mine Levels 436 and 486 Using Geologic Structures Data, and Modelling Software – Dips and Unwedge:  a Part of dp1 Project (Mine Layout and Technology) of the Sustainable Underground Mining (Sum) Project

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Oludare Joseph Olufe; [2021]
    Nyckelord :Drift stability analysis; underground excavation reinforcement; underground mining stability assessment; geologic structures; wedges modelling; rock mechanical analysis; Unwedge program; Dips program;

The population explosion is driving massive urbanization and infrastructure developments across the globe, which result in huge demand for metals, especially steel. LÄS MER

  4. 4. Analysis of Seismic Data Acquired in the Hverahlíð Geothermal Area

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Agnieszka Stoch; [2020]
    Nyckelord :Hverahlíð geothermal area; reflection seismic; virtual reflection seismic profiling; virtual shot gather; cross-correlation; autocorrelation;

    Sammanfattning : Volcanic rifting environments, such as in Iceland, are challenging for conventional seismic reflection methods using active surface seismic sources. This study demonstrates the potential of a novel technique, called Virtual Reflection Seismic Profiling (VRSP) for imaging reflections in geothermal regions, like Hverahlíð, where a dense seismic array recorded a number of local microearthquakes for cross-correlation.

  5. 5. Investigation Of Source Parameters Of Earthquakes In Northern Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :María González-Caneda; [2019]
    Nyckelord :spectral analysis; earthquake source observations; ω-2 source model; moment magnitude; local magnitude; Northern Sweden seismicity.;

    Sammanfattning : By studying the frequency domain of seismic signals generated by earthquakes, the source parameters can be recovered, i.e., the seismic moment (M0) and the stress drop (Δσ). LÄS MER
