Method and provenance

Production method

Optical displacement tracking with 221 Sentinel-2 images from February 2017 through 24 August 2026, supplemented by geomorphological interpretation of the source area.

Provenance

Authored by Tianchu Wang, Shinji Sassa, Wentao Yang, Rushi Li, Chong Xu, and Wenwen Qi; peer-reviewed and published online in Landslides (Springer Nature) on 14 September 2026.

Validation

Journal Article Accepted By Publisher

Uncertainty

The source discusses optical tracking and registration constraints. It does not perform radar correlation, hydraulic simulation, or an independent numerical flood-stage reconstruction.

Limitations

A study of pre-failure deformation and interpretation, not causal proof of a particular flood-generation mechanism. Crossref identifies publisher text-and-data-mining terms; the earlier CC BY 4.0 assertion was not established. The publisher labels the contribution News/Kyoto Commitment; received and accepted dates do not establish an independent validation of the causal interpretation.
