Do deformation patterns and initial failure timing of rock-slope instabilities in Norway relate to permafrost dynamics?
International audience Deep-seated and slow moving rock-slope instabilities are common in the Norwegian valley and fjord system. While many sudden rock-slope failures happened shortly after deglaciation, there is still a number of recently deforming unstable rock slopes. We have dated several slip s...
