Geohazard information for the masses

Month: May 2017

Time series of crack widening and air temperature under long-term ‘winter’ conditions. Spikes occurred when visiting the chamber; each visit lasted <2 min. The photographs show plan views of the top of the ice vein on days 1, 12 and 51. A vertical face of the block is visible in the lower third of each photograph. (after jia et al., 2017)

An uncommon look at frost wedging in the lab under ‘autumn’, ‘winter’, and ‘spring’ conditions

Frost wedging describes the process by which pressure from the expansion of freezing water in pre-exising fractures generates sufficient tensile stress to propagate the crack further into intact rock. Although this seems like a reasonably common sense interpretation (given the transition from water to ice involves a 9% expansion that’s often associated with the bursting […]

Candidate: Jonas von Wartburg Supervisors: Susan Ivy-Ochs, Kerry Leith, Jordan Aaron, Prof. Dr. Silvana Martin (U. Padua) Institution: ETH Zurich, University of Padua Activity: Beginning Fall 2017 Introduction A detailed understanding of prehistoric landslides provides fundamental information on the inherent causes of massive rock slope failures in the Alps. In Trentino, a key issue in assessing hazards […]
