A susceptibility map for retrogressive thaw slumps across the circumpolar permafrost region, created by the Government of Yukon. The model predicts high susceptibility in continuous permafrost regions above the 60th latitude, including northern Alaska, northwestern Canada, the Yamal Peninsula, eastern Russia, and the Qinghai-Tibetan Plateau. It was last updated on April 17, 2026.
Use Cases
- Modeling landscape evolution risks based on predicted susceptibility scores.
- Assessing infrastructure vulnerability in high-susceptibility regions like northern Alaska and northwestern Canada.
- Analyzing the impact of thaw season climatic conditions on permafrost hazard occurrence.
- Studying the relationship between soil properties and retrogressive thaw slump susceptibility on a circumpolar scale.
Strengths
- Provides the first susceptibility map for retrogressive thaw slumps across the Northern Hemisphere.
- Model results are based on environmental factors including air temperature and soil properties.
- Last updated on April 17, 2026, indicating recent maintenance.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
