1. 1. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

   Författare :Edwin Obando; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

   Sammanfattning : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. LÄS MER

3. 2. Seismic Investigations at the Ketzin CO2 Injection Site, Germany: Applications to Subsurface Feature Mapping and CO2 Seismic Response Modeling

   Författare :Sayed Hesammoddin Kazemeini; Christopher Juhlin; Sergey Fomel; Milovan Urosevic; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic resolution; Spectral blueing; CO2 seismic response; Continuous Wavelet Transform Decomposition; 3D seismic baseline; CO2SINK project; Solid earth physics; Fasta jordens fysik; geofysik; med inriktning mot fasta jordens fysik; Geophysics Specialized In Solid Earth;

   Sammanfattning : 3D seismic data are widely used for many different purposes. Despite different objectives, a common goal in almost all 3D seismic programs is to attain better understanding of the subsurface features. LÄS MER

4. 3. Quantifying the Seismic Response of Underground Structures via Seismic Full Waveform Inversion : Experiences from Case Studies and Synthetic Benchmarks

   Författare :Fengjiao Zhang; Christopher Juhlin; Ari Tryggvason; Yanghua Wang; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; full waveform inversion; waveform tomography; CO2 monitoring; CO2 sequestration; time lapse seismic; Inversion; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Sammanfattning : Seismic full waveform inversion (waveform tomography) is a method to reconstruct the underground velocity field in high resolution using seismic data. The method was first introduced during the 1980’s and became computationally feasible during the late 1990’s when the method was implemented in the frequency domain. LÄS MER

5. 4. Three-component digital-based seismic landstreamer : Methodologies for infrastructure planning applications

   Författare :Bojan Brodic; Alireza Malehmir; Christopher Juhlin; André Pugin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

   Sammanfattning : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. LÄS MER

7. 5. Simulating Earthquake Rupture and Near-Fault Fracture Response

   Författare :Billy Fälth; Björn Lund; Roland Roberts; Harald Hökmark; Eric Dunham; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. LÄS MER
