1. 1. Statistical Seismology Studies in Central America : b-value, seismic hazard and seismic quiescence

   Författare :David Aníbal Monterroso Juárez; Ota Kulhánek; Stefan Wiemer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; b-value; seismic hazard; Monte Carlo; seismic quiescence; Central America; stress; Geofysik; Geophysics; Geofysik;

   Sammanfattning : The present thesis collects results of research applying theory and methods of statistical seismology to the seismicity of Central America, a region with a complex tectonic setting controlled by the interaction of four major plates, namely the Caribbean, Cocos, Nazca and North American plates.Three different earthquake catalogues were used for studies focused on stress in a tectonic volume, seismic hazard maps and seismicity patterns (precursors), covering the region 94ºW to 81ºW and 5ºN to 20ºN.

3. 2. Earthquake Sources, the Stress Field and Seismic Hazard : A Study in Eritrea and its Surrounding

   Författare :Lijam Zemichael Hagos; Roland Roberts; Hossein Shomali; Kuvvet Atakan; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Seismic hazard; Focal mechanism; Moment tensor inversion; Stress field; Afar depression; Eritrea; Geovetenskap; Earth sciences; Geovetenskap;

   Sammanfattning : Presented in this thesis are some basic concepts and applications of seismic hazard analysis and the elements that influence the amplitude and geometric attenuation of earthquake ground motion. This thesis centers on the identification of the styles of failure, focal mechanisms, and the state of regional stress in the study area. LÄS MER

4. 3. Earthquake Sources and Hazard in northern Central America

   Författare :Diego José Cáceres Calix; Ota Kulhánek; Vladimir Schenk; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Northern Central America; Probabilistic Seismic Hazard; Body waveform modeling; Seismic Active Deformation; Earthquake Triggering; Geofysik; Geophysics; Geofysik;

   Sammanfattning : Northern Central America is a tectonically complex zone defined by its borders with Cocos and North America plates. The Middle America subduction zone and the strike-slip motion along the North America-Caribbean plate boundary, in that order, control most of its deformation. LÄS MER

5. 4. Prediction of Strong Ground Motion and Hazard Uncertainties

   Författare :Behrooz Tavakoli; Ota Kulhanek; Dieter Mayer-Rosa; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Disaggregation; Ground motion; Monte Carlo simulation; Seismic hazard; Geofysik; Geophysics; Geofysik; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : The purpose of this thesis is to provide a detailed description of recent methods and scientific basis for characterizing earthquake sources within a certain region with distinct tectonic environments. The focus will be on those characteristics that are most significant to the ground-shaking hazard and on how we can incorporate our current knowledge into hazard analyses for engineering design purposes.

7. 5. Towards reliable seismic hazard assessment in underground mines

   Författare :Wille Törnman; Savka Dineva; Jesper Martinsson; Adam Jonsson; Björn Lund; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to  design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.
