Completed catalogue assessment

Eligibility decision
Include · Included Resource Version Qualified
Assessment date
28 September 2026
Decision reason
The ADRC event-report resource existed in the earlier source inventory, but its native PDF is mutable. The current retrieved PDF is 82 pages and dated 27 September 2026, after the 24 September cutoff, whereas the earlier inventory described 21 pages through 1 September. Retain the resource identity with this version qualification; exclude the current PDF version from pre-cutoff content synthesis because the earlier body was not recovered. The current report is a compilation, not independent causal confirmation.

Method and provenance

Production method
ADRC assembled a dated chronology and impact summary from official and institutional sources, including IRDR, NDRRMA, DHM, UNOSAT, BIPAD, Sentinel Asia, and the International Charter.
Provenance
Compiled and published by the Asian Disaster Reduction Center under the event's GLIDE identifier, with individual maps, figures, and statements attributed in the report.
Validation
Provider Published
Uncertainty
The report consolidates early operational sources whose casualty, missing-person, and impact figures changed rapidly during the reporting period.
Limitations
A secondary 21-page synthesis rather than an original field survey; figures reflect the source dates shown, and several maps and images retain the constraints of their upstream providers.
