CLaSH — scientific event StoryMap and annotated evidence | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: Live scientific synthesis with annotated satellite images, lake/source observations, hydrograph and seismic figures.
Review findings: One post-collapse caption says 28 August 2025; some Copernicus links encode 2023 and non-Nepal coordinates. Preserve conflicts. Figures are not downloadable original raster/vector measurements. Upload dates are not acquisition dates; licenceInfo is empty. Automated appraisal; no independent human screening or manuscript inclusion assigned. Asset assessment REV-20260908-ASSETS-002 completed 25 newly added or rediscovered asset records; 23 retain explicit follow-up. Titles, technical fields, source versions and interpretation limits are recorded in the asset-review export. Resource eligibility and manuscript inclusion remain separate.
