Geophysical analysis reveals thaw depth variability in permafrost due to land use and climate factors.

Thaw depths range from 0.2 to over 1 meter, indicating significant variability due to land use and natural features.
Electrical resistivity tomography identified high-resistivity zones associated with ice-rich permafrost, and low-resistivity features likely linked to thaw zones.
Ground penetrating radar supported the identification of subsurface stratigraphy, revealing important ice-rich layers in permafrost areas.
Findings emphasize the impact of infrastructure on permafrost conditions, suggesting the need for localized assessments of ground stability.

Ekimova et al. (2025) studied this question.
