Method and provenance
- Production method
- UNOSAT mapped cumulative mudflow and rockflow extent from PlanetScope imagery acquired 26 August and Sentinel-2 imagery acquired 27 August 2026, then assessed potentially affected roads and buildings against the mapped area.
- Provenance
- Produced by UNOSAT under code FL20260826NPL and published through HDX. The current File Geodatabase asset is byte-identical to the archive exposed by three related UNOSAT records and contains the complete multi-product event geodatabase.
- Validation
- Not Validated
- Uncertainty
- UNOSAT identifies the analysis as preliminary and not field validated. Interpretation depends on source-image characteristics, and exposure indicates intersection with or proximity to mapped affected areas rather than confirmed damage.
- Limitations
- The assessment covers approximately 350 km² and is not a field-verified inventory. Minor structural damage may not be visible in imagery.
