Description :
The AA. describe geocryological conditions (active layer depths, permafrost temperatures, ground thermal properties and cryostratigraphy) in the Klyuchevskaya volcano group and estimate the spatial distribution of permafrost using a simple statistical model. Measures mean annual ground temperatures vary from near 0°C around 950m a.s.l. to -7°C at 2500m a.s.l. and permafrost is predicted to occur at elevations >700m a.s.l. Heat transfer modelling indicates that the maximum permafrost thickness is about 1000m for the highest summits (5000m a.s.l.).
