A total of more than 140 000 kg of smallmagnitude rockfall deposits was measured in eight rockfall collectors of altogether 940m² in size between 1999–2003 below a 400–600m high rock face in the Reintal, German Alps. Measurements were conducted ...

Three case-histories are aimed to show possibilities how to use results of dilatometric measurements of relative displacements on rock cracks to assess actual rock slope instability and to make time-predictions of a rock fall. The prediction of a collapse ...
