Application of Geographic Information Systems (GIS) in Mapping Geological Hazards

Thesis Abstract

Abstract
Geological hazards pose significant threats to communities and infrastructure worldwide. The accurate mapping and assessment of these hazards are crucial for effective risk management and disaster preparedness. Geographic Information Systems (GIS) have emerged as powerful tools for analyzing and visualizing spatial data, making them invaluable for mapping geological hazards. This thesis explores the application of GIS in mapping geological hazards, with a focus on enhancing hazard identification, assessment, and mitigation strategies. Chapter One provides an introduction to the research topic, highlighting the background of the study, the problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review in Chapter Two delves into ten key aspects related to GIS applications in mapping geological hazards, providing a comprehensive overview of existing research and methodologies. Chapter Three outlines the research methodology, detailing the steps taken to collect and analyze data for mapping geological hazards using GIS. This chapter includes discussions on data collection techniques, GIS software selection, data processing methods, hazard mapping algorithms, and validation procedures. Additionally, it covers the integration of remote sensing data and field surveys to enhance the accuracy of hazard mapping. In Chapter Four, the findings of the research are presented and discussed in detail. The chapter explores the effectiveness of GIS in mapping various geological hazards such as landslides, earthquakes, volcanic eruptions, and tsunamis. It discusses the spatial analysis techniques used to identify hazard-prone areas, assess vulnerability, and prioritize mitigation measures. The chapter also examines case studies showcasing the practical application of GIS in real-world hazard mapping projects. Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research, and offering recommendations for future studies. The conclusion underscores the importance of integrating GIS technologies with traditional hazard assessment methods to improve the accuracy and reliability of hazard maps. Overall, this thesis contributes to the growing body of knowledge on GIS applications in mapping geological hazards and provides valuable insights for researchers, policymakers, and practitioners in the field of geology and disaster management.
