Catalogue assessment and metadata evidence

Follow-up needed

Completed catalogue decisions are recorded separately from technical inspection and scientific validation. Access and metadata evidence retain their original dates and scope.

Completed catalogue assessment

Eligibility decision: Include · Retain Ancillary Preview
Assessment date: 28 September 2026
Decision reason: Original metadata identifies an associated preview. Retain the link without assigning raster measurement properties or independent observation status; no image inspection.
Information role: Preview Not Independent Observation
Scientific validation: not_performed_by_catalogue_review
Recorded access: Reachable Without Authentication
Source assessment: Original metadata identifies an associated preview. Retain the link without assigning raster measurement properties or independent observation status; no image inspection.
Limitations: The right image is described as post-collapse, but the caption says 28 August 2025. The catalogue preserves the contradiction and does not invent a corrected acquisition date.
Rights status: Not Stated
Rights note: StoryMap licenceInfo is empty. Individual figure credits identify upstream contributors; they do not establish a blanket licence for the annotated figure or underlying scientific data.
Redistribution: Metadata and links only; no third-party asset bodies published by this catalogue.
Assessment evidence: Source 1: storymaps.arcgis.com

Resolve the paired image’s 2025 caption before assigning a post-event acquisition date.
Resolve the specific figure/video reuse terms from the credited contributor; the StoryMap supplies no general licence.
