DInSAR techniques for the assessment of sinkhole hazard

OLYMPUS DIGITAL CAMERA Sinkholes occur as sudden collapses of the ground, related to natural cavities produced by karst processes in soluble rocks, or to man-made cavities deriving from different types of human activities in different historical ages. Sinkholes are widespread all over the world, and the related hazard is extremely high, with very severe damage to built-up areas and human infrastructures, and heavy losses to the ...

Micro-seismic network at the Carrel Hut on the Matterhorn

OLYMPUS DIGITAL CAMERA The permafrost degradation is a probable cause of the increase of rock instabilities and rock falls observed in recent years in high mountain areas. It causes the thaw of the ice filling rock discontinuities producing water that subsequently freezes again, inducing stresses that lead to rock falls. Rock-falls are among the most hazardous instability processes in high mountain environments because of their velocity and the difficulty to ...
