Description :
Active-layer detachment failures triggered weeks to months after forest fire in central Mackenzie Valley (65°N, discontinuous permafrost zone) are compared to others generated almost immediately by summer meteorological conditions on the Fosheim Peninsula, Ellesmere Island (80°N, continuous permafrost zone). The AA. focus here on the environmental triggers of detachment failure, frequency-magnitude relations, and discuss possible climate change impacts on initiation frequency.
