Abstract: Geohazards pose significant threats to communities and infrastructure worldwide, necessitating effective assessment and management strategies. Remote sensing technologies have emerged as invaluable tools for identifying, mapping, and monitoring various geohazards, including landslides, earthquakes, volcanic eruptions, and sinkholes. This paper provides a comprehensive overview of the applications of remote sensing in geohazard assessment and risk management. It discusses the principles behind remote sensing techniques and explores their utilization in detecting and monitoring different types of geohazards. Furthermore, the paper examines how remote sensing data can be integrated with geographical information systems (GIS) to enhance geohazard risk assessment and management. Case studies highlighting successful applications of remote sensing in geohazard analysis are presented, along with discussions on challenges and future directions in the field. Overall, this paper emphasizes the critical role of remote sensing in enhancing our understanding of geohazards and facilitating proactive measures to mitigate their impact.
