- Mudflow And Rockflow Extent, Population Exposure, Earth Observation
Method and provenance
- Production method
- UNOSAT derived cumulative mudflow and rockflow extent from PlanetScope imagery acquired 26 August and Sentinel-2 imagery acquired 27 August 2026 and combined it with WorldPop data to estimate population exposure.
- Provenance
- Produced by UNOSAT under code FL20260826NPL and published through HDX. The current File Geodatabase is part of the shared multi-product event archive, and the population-exposure workbook is byte-identical to the workbook listed for the Rasuwa record.
- Validation
- Not Validated
- Uncertainty
- The assessment is preliminary and not field validated. Exposure estimates depend on the interpreted extent, source-image characteristics, and the population surface.
- Limitations
- Approximately 103 km² were analysed. The reported population is estimated to be exposed to or living near mapped affected areas and should not be interpreted as a confirmed casualty or displacement count.
