Short summary
Below ground pressurization occurs when there is more moisture in the soil pores than normal, and it can potentially result in landscape degradation. We mapped features that are caused by this overpressurization and generated susceptibility maps to find other areas on the landscape that could be susceptible in the future. The susceptibility maps identified areas that may be sensitive to pressurization and help improve our understanding of potentially hazardous permafrost degradation.
