Geological Disaster: An Overview

Geological disasters are catastrophic events that result from natural processes in the Earth's crust, including earthquakes, landslides, rock falls, ground fissures, etc. These disasters can cause significant damage to infrastructure, property, and human lives, as well as impact the environment and natural resources. This chapter provides an overview of the origin and types of main terrestrial geological disasters, and introduces the risk assessment and management strategies used for geological disaster researches by using equipment-based and remote sensing-based approaches. Key findings and insights from recent researches, as well as gaps and challenges in current research and management efforts are also discussed. The futural directions and opportunities presented in this chapter can help to inform stakeholders and researchers on the potential approaches for managing and mitigating the impact of geological disasters.
