Abstract
This thesis investigates the relationship between seismic activity and subsurface structures using advanced geophysical imaging techniques. The study aims to enhance our understanding of the geological processes that lead to seismic events and to improve the accuracy of seismic hazard assessments. The research employs a combination of geophysical methods, including seismic reflection, refraction, and tomography, to image the subsurface structures and analyze their relationship with seismic activity. The introduction provides a background to the study, highlighting the significance of understanding seismic activity and its impact on society. The problem statement emphasizes the need to investigate the link between subsurface structures and seismic events to better predict and mitigate seismic hazards. The objectives of the study are outlined, focusing on the identification of key subsurface structures and their influence on seismic activity. The literature review explores existing research on seismic activity and subsurface structures, providing a comprehensive overview of the current state of knowledge in the field. The review covers topics such as fault systems, stress accumulation, and seismic wave propagation, offering insights into the mechanisms that control seismic events. The research methodology details the geophysical imaging techniques used in the study, including seismic reflection profiling, seismic refraction surveys, and seismic tomography.
