  2. 1. Structural Earthquake Response Analysis

    Author : Hamid Movaffaghi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; Earthquake excitation; global and local optimization; viscoelastic passive dampers; stochastic simulation; structural earthquake response analysis;

    Abstract : AbstractEarthquakes are one of the most dangerous natural phenomena causing damage to buildings and other structures as well as injury and death of people. These destructive processes can never be prevented to happen, but their impact on the structures can be minimized. READ MORE

  4. 2. Physics of Aftershocks in the South Iceland Seismic Zone : Insights into the earthquake process from statistics and numerical modelling of aftershock sequences

    Author : Mattias Lindman; Roland Roberts; Björn Lund; David Marsan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake processes; Aftershocks; Physics of aftershocks; Omori law; Postseismic processes; Pore pressure diffusion; Poroelasticity; Statistical seismology; Self-organised criticality; Interevent time distributions; Waiting time distributions; Geophysics; Geofysik;

    Abstract : In seismology, an important goal is to attain a better understanding of the earthquake process. In this study of the physics of aftershock generation, I couple statistical analysis with modelling of physical processes in the postseismic period. READ MORE

  5. 3. Location and Relocation of Seismic Sources

    Author : Ka Lok Li; Ólafur Gudmundsson; Roland Roberts; Ari Tryggvason; Lars Ottemöller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake location; Earthquake relocation; Tremor location; Bayesian inversion; Correlation; Earthquake catalog; Iceland; Seismicity; Interferometry; Inverse theory; Volcanic tremor; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : This dissertation is a comprehensive summary of four papers on the development and application of new strategies for locating tremor and relocating events in earthquake catalogs.In the first paper, two new strategies for relocating events in a catalog are introduced. READ MORE

  6. 4. Human Adaptation to Danger

    Author : Claes Wallenius; Curt Johansson; Gerry Larsson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Coping; Adaptation; Performance; Reactions; Stress; Danger; Life-Threat; Earthquake; Peacekeeping; Disaster; Psykologi; Stress; Peacekeeping; Ledarskap under påfrestande förhållanden;

    Abstract : The overall purpose of the thesis was to increase knowledge concerning how people adapt psychologically when faced with a real danger incident, and what implications these reactions and adaptation mechanisms have upon immediate performance. The thesis is based on three empirical studies concerning people with personal experience of dangerous incidents. READ MORE

  7. 5. Seismicity and crustal structure in Iceland

    Author : Claudia Abril; Ólafur Gudmundsson; Vala Hjörleifsdóttir; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake relocation; local earthquake tomography;

    Abstract : The main goal of this Ph.D. thesis is to improve locations of earthquake hypocenters and to resolve heterogeneous crustal structure and its effects on travel times. The data and case studies are drawn from the Icelandic national SIL network and the temporary NICE project deploy-ment in the Tjörnes Fracture Zone. READ MORE
