(PhysOrg.com) -- Based on the statistical analysis of 20 rock-falls in the Alps and the seismic signals recorded at the same time, ETH Zurich scientists have developed a new method allowing the volume and extent of a rock-fall to be determined within a few minutes. The method enables a quick hazard assessment to be made and means action can be taken swiftly.
