Land subsidence and landslides are intricate global phenomena influenced by a combination of natural processes and human activities, presenting significant risks to the environment and infrastructure. Therefore, effective mitigation requires a well-organized monitoring strategy for both land subsidence and shear displacement calculation. This study presents a novel monitoring technique that utilizes distributed optical fiber for comprehensive modeling of land subsidence and shear displacement. Thorough laboratory and field experiments have been conducted to evaluate the optical fiber-based BOTDR/BOTDA for these applications. The results of these experiments suggest that this technique is a highly reliable and effective solution for quantifying both land subsidence and shear displacement.
