Topic: Adapting Rainfall Thresholds for Landslide Prediction: A Comprehensive Approach for Early Warning Systems

Abstract: Rainfall-induced landslides are a critical challenge faced by many regions worldwide, posing severe threats to human life, infrastructure, and the environment. As extreme weather events become more frequent due to climate change, there is an urgent need for more effective methods to predict and mitigate the impacts of landslides. Universal rainfall thresholds should be developed and adapted in various climates and geological settings to forecast landslides and support the establishment of early warning systems. Through an analysis of landslide-triggering rainfall data from multiple case studies, this research proposes two essential thresholds which are the Intensity-Duration threshold (I-D) and Cumulative-Duration threshold (C-D). These thresholds serve as predictive tools by identifying critical rainfall patterns often preceding landslide occurrences. To enhance their accuracy, advanced computational techniques such as Artificial Neural Networks (ANNs) are employed, allowing for the modelling of complex relationships between rainfall intensity, duration, and the likelihood of landslides. In addition, the study examines how key factors such as soil characteristics, rock type, and slope dynamics contribute to regional variations in landslide susceptibility. By integrating these factors into rainfall threshold models, it becomes possible to develop highly localized early warning systems capable of providing timely alerts and reducing the risk of disaster. This will explore how these global thresholds can be adapted to different regions and environments, offering a critical tool for governments and disaster management agencies. The aim is to enhance preparedness, reduce casualties, and safeguard communities from the devastating effects of rainfall-induced landslides.
