⛰️ '''Landslip coverage''' provides insurance protection against damage to property caused by the downward movement of sloping ground — a peril that encompasses landslides, mudslides, and the gradual or sudden lateral displacement of earth on an incline. Within [[Definition:Property insurance | property insurance]], landslip is typically grouped alongside [[Definition:Subsidence | subsidence]] and [[Definition:Ground heave | ground heave]] as part of a suite of ground movement perils, though the specific treatment varies by market and product. In the United Kingdom, standard household and commercial property policies generally include landslip as a named peril, while in other jurisdictions — particularly those in mountainous or seismically active regions like Japan, Hong Kong, and parts of continental Europe — it may be covered under broader [[Definition:Earth movement coverage | earth movement]] provisions or require separate endorsement.

⚙️ When a landslip event occurs, the [[Definition:Insurance carrier | insurer]]'s response typically involves deploying a [[Definition:Loss adjuster (loss adjuster/claims adjuster) | loss adjuster]] alongside geotechnical specialists to assess the cause, extent, and stability of the ground movement before authorizing repairs or settlement. Claims can be complex and prolonged: stabilizing a slope may require retaining walls, soil nailing, or drainage systems in addition to repairing the structural damage to the building itself. Policies covering landslip frequently apply a higher [[Definition:Deductible | deductible]] than for other property perils, reflecting the severity and complexity of these claims. [[Definition:Underwriting | Underwriting]] for landslip risk draws on geological surveys, topographic data, historical event databases, and increasingly on [[Definition:Remote sensing | remote sensing]] technologies such as LiDAR and satellite-based interferometric synthetic aperture radar (InSAR) to identify vulnerable slopes and monitor creep before it escalates to failure.

🌧️ Landslip risk carries growing importance for the insurance industry as [[Definition:Climate change | climate change]] intensifies rainfall patterns and accelerates soil erosion in many regions. Catastrophic landslide events — such as those triggered by typhoons in the Philippines and Japan, heavy monsoon rains in India and Southeast Asia, or wildfire-denuded slopes in California and Australia — can generate concentrated losses that challenge [[Definition:Loss reserving | reserves]] and test [[Definition:Reinsurance | reinsurance]] programs. In Hong Kong, the Geotechnical Engineering Office's extensive slope safety program has been a model for risk reduction, and insurers operating there factor government slope maintenance data into their risk assessment. For global [[Definition:Reinsurer | reinsurers]] and [[Definition:Catastrophe model | catastrophe modelers]], the challenge lies in the localized and highly variable nature of landslip — a peril that resists the broad-brush probabilistic modeling approaches used for earthquakes or windstorms, demanding instead granular, site-specific analysis.
