  1. 1. Tunnel Seismic Prediction in Stockholm Bypass

    University essay from KTH/Jord- och bergmekanik

    Author : Matilda Wessén; Janita Österberg; [2021]
    Keywords : Tunnel Seismic Prediction; TSP; Seismic waves; Stockholm Bypass; Geological mapping; Measurement While Drilling; Tunnel Seismic Prediction; TSP; Seismiska vågor; Förbifart Stockholm; Bergkartering; Measurement While Drilling;

    Abstract : Tunnel Seismic Prediction (TSP) is a geophysical investigation method used to predict the rock conditions ahead of the tunnel face. The method has been used in different types of rock and rock conditions. READ MORE

  3. 2. Determining shallow P-wave velocity and its engineering implication in Adama City, Ethiopia

    University essay from Uppsala universitet/Geofysik; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Tasnim Laskar; [2019]
    Keywords : Ethiopia; seismic refraction; earthquake;

    Abstract : A great number of the urban areas in Ethiopia are situated within the Great Rift Valley of Ethiopia, a system consisting of depressions and large faults. As a region with significant seismic activities, it is vital that careful planning is implemented to avoid constructing buildings on flat surfaces as they can amplify ground motion in the case of an earthquake.

  4. 3. Characterizing Subsurface Structure of Two Contrasting Sites in the Main Ethiopian Rift

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ebba Hansson; [2019]
    Keywords : Ethiopia; Main Ethiopian Rift; seismic refraction; subsurface structure;

    Abstract : The Main Ethiopian Rift is a part of the East African Rift, from where the African plate is being teared apart and separated from the Indian and the Arabian plate. Even though earthquakes in this area are relatively less frequent, the subsurface structure is a subject of big research interest, since information about the subsurface layers has considerable relevance when it comes to site amplication related to earthquakes.

  5. 4. Classification of Seismic Body Wave Phases Using Supervised Learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Gunnar Atli Eggertsson; [2019]
    Keywords : ;

    Abstract : The task of accurately distinguishing between arrivals of different types of seismic waves is a common and important task within the field of seismology. For data generated by seismic stations operated by SNSN this task generally requires manual effort. READ MORE

  6. 5. An Innovative In-Tunnel Seismic Study for Sustainably Extracting Apatite Ore at the Siilinjärvi Mine, Eastern Finland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anna Donczew; [2019]
    Keywords : in-tunnel seismic; reflection seismic; traveltime tomography; carbonatites; shear zones; Siilinjärvi; tunnelseismik; reflektionsseismik; restidstomografi; karbonatiter; skjuvzoner; Siilinjärvi;

    Abstract : Siilinjärvi located in eastern Finland is presently the only phosphate mine with significant phosphorus production in western Europe. Phosphate rock and phosphorus are known as a critical raw material for the European Union due to their economic importance and being prone to the supply risks. READ MORE
