The effectiveness of Fiber Bragg Grating (FBG) sensors in Landslide monitoring is analyzed in this review article, which also highlights some possible future avenues for these sensors. Advanced monitoring methods are required for early detection and risk mitigation since landslides pose serious dangers to human safety and infrastructure. FBG sensors have become important instruments in geotechnical monitoring because of their great sensitivity and capacity to sense displacement, temperature, and strain. The fundamentals of FBG technology are covered in the article, the paper also discusses the difficulties in deploying FBG sensors in various geological settings and highlights the need for more study to improve their performance and incorporation into early warning systems. This work attempts to give insights into the current practices of FBG sensor applications in landslide monitoring by synthesizing existing literature and case studies. It also outlines future research directions to increase the efficacy of FBG sensors in hazard prediction and management.
