Permafrost and periglacial related hazards
Permafrost isn't a geologic hazard until it starts to melt. Unfortunately, permafrost is very sensitive to disturbance by humans and nature. As a result, it is important to consider whether or not permafrost is present when developing any kind of infrastructure. Researchers suggest that permafrost is getting warmer due to rising temperatures at northern latitudes.
