This half-day workshop introduces the concepts and practical methods for developing hydrometeorological thresholds for regional Landslide Early Warning Systems (LEWS). Participants will learn how to design a regional LEWS using available data through a combination of conceptual discussions and hands-on exercises.

The workshop begins by introducing the various regional landslide hazard assessment methods and explaining their conceptual foundations. It then discusses landslide databases and the challenges associated with developing reliable thresholds. Participants will work with rainfall time series and potential hydrological variables that are informative for hydrometeorological threshold development. These datasets will be used to derive different threshold approaches, followed by discussions on their strengths and limitations. Special attention will be given to the transient changes in thresholds resulting from land-use and climate change.

After the workshop and throughout the conference, participants will have the opportunity to discuss their own datasets and regional LEWS threshold challenges with the instructor.

As part of the World Landslide Forum 7 (WLF7), this short course introduces participants to the principles, methodologies, and practical applications of satellite-based deformation monitoring and artificial intelligence (AI) for detecting, monitoring, and forecasting slow-moving landslides. The workshop focuses on integrating Interferometric Synthetic Aperture Radar (InSAR) observations with machine learning approaches to support landslide hazard assessment, early warning systems, infrastructure management, and risk-informed decision-making.

Slow-moving landslides often remain active for months or years following triggering events such as earthquakes and extreme rainfall, posing long-term threats to communities, transportation networks, critical infrastructure, and economic activities. Recent advances in satellite remote sensing have significantly enhanced our ability to measure ground deformation with millimeter-scale precision over large areas, while developments in AI have created new opportunities to forecast future slope behavior from large deformation datasets.

This course is intended for researchers, geohazard specialists, disaster risk reduction professionals, engineers, GIS and remote sensing practitioners, government agencies, infrastructure managers, and students interested in operational landslide monitoring and forecasting.

Reliable prediction of rainfall-induced landslides requires two fundamental components: high-quality hydrometeorological data and systematic records of landslide occurrence. In many regions of the world, particularly in developing and data-scarce environments, limitations in monitoring infrastructure create significant challenges for landslide forecasting and early warning.

This workshop explores how satellite-derived rainfall and soil moisture products, landslide catalogs compiled from documentary sources, and modern digital twin technologies can be integrated to improve landslide prediction and risk assessment. Participants will gain insight into the scientific foundations of rainfall threshold modeling, the opportunities and limitations of satellite observations, and emerging approaches for building geospatial digital twins that support next-generation landslide early warning systems.

The workshop combines lectures, international case studies, and guided discussions to provide participants with both conceptual understanding and practical perspectives on operational landslide forecasting.
