This book presents a comprehensive and critical examination of the management of major disasters and natural hazards, drawing on scientific evidence, historical events, and contemporary management practices. It explores how large-scale geological hazards such as earthquakes, volcanic activity, and related secondary impacts are assessed, modelled, and managed to reduce human and economic losses. The book emphasises the importance of risk assessment, loss estimation, and analytical tools in supporting informed decision-making before and after disaster events.

The book further examines post-disaster reconstruction, institutional challenges, and social consequences arising from catastrophic events across different regions of the world. It highlights how historical experiences and case-based analysis contribute to improved preparedness, response coordination, and long-term recovery planning. Attention is given to both technical and human dimensions of disaster management, including policy implementation, resilience building, and lessons learned from past failures. By integrating geoscientific research with management strategies, the book provides a structured understanding of major hazards. It is a valuable resource for students, researchers, planners, and professionals engaged in disaster and hazard management.
