DEUQUA Publication
Precise long-term measurements of rockfalls in steep alpine rock faces are scarce. This makes documenting current changes in permafrost and steep alpine rockwalls all the more important. In a new paper (published on 09.09.2024), we have condensed the key findings from our research at the Open-Air-Lab Kitzsteinhorn into ten concise pages. Spoiler alert: Even at great rock depths, we’re seeing significant permafrost warming, and glacier retreat is dramatically increasing rockfall activity.

PROJECT RockSAR
Large mass movements are often preceded by deformation in the millimeter range. Small-scale precursory deformation is extremely hard to identify and hence can only be studied at known, active slope failures. In the ARGE ALP project “RockSAR – Identification of millimetric rock slope deformation with InSAR” we are performing extensive InSAR analyses (Interferometric Synthetic Aperture Radar) to identify currently unknown, slow rock slope failures in the Eastern Alps.

RADON Monitoring
Can radon detectors be used for rockfall monitoring and prediction? At the prominent Ingelsberg rockslide (Bad Hofgastein) we and our colleagues from IAF-Radioökologie GmbH (Dresden, Germany, www.iaf-dresden.de) and the Geological Survey of Salzburg are the first to investigate the applicability of radon measurements for early warning systems. As rock slope activity increases, new cracks and fissures appear through which the radioactive element radon can be exhaled. Already a few thousand radon atoms are sufficient to detect changes in radon concentration and slope movement rates.
We are very much looking forward to the first results and thank the municipality of Bad Hofgastein for the great support!

PUBLICATION Glacial Lakes in Austria
Glaciers in Austria and the entire Alps are shrinking at a record-setting pace, yet little is known about the exposed proglacial areas and the subglacial relief. In a brand new study we have now estimated the potential formation of future glacial lakes in Austria. We combined several ice thickness models to localize glacier bed overdeepenings (GBO) and found 42 locations where lake formation is highly likely after deglaciation. The full study is available at ESPL (Earth Surface Processes and Landforms).

FIELDWORK Crackmeter Installation
Open-Air-Lab Kitzsteinhorn: Rockfall monitoring expanded! Rockfall events are often preceded by minimal surface displacement (joint aperture changes), which can be detected with high-precision crackmeters. Within the RIDGES project we recently installed four brand-new crackmeters in the north-face of the Kitzsteinhorn and hope to gain new insights into the kinematics of high-alpine rockwalls, which are heavily affected by atmospheric warming and glacier retreat.
PUBLICATION Earth Surface Dynamics I
In the first of two companion papers we investigated the relationship between dramatic recent glacier retreat and high-alpine rockfall occurrence. The rockfall dataset analyzed is the most extensive of its kind worldwide and revealed a significant pattern: Rockwalls that became deglaciated in the last years and decades are particularly prone to rockfall.
Check out the latest issue of the internationally renowned magazine "Earth Surface Dynamics" and read the full paper which has been selected as "Highlight Article" by the journal editors.

MEDIA ORF news article Sattelkar
In high-alpine cirques, climate change-induced permafrost degradation and an increase in liquid precipitation are projected to promote the availability of fresh, unconsolidated sediments. The relevance of cirques as source areas of hazardous mass movements is therefore expected to grow significantly. Together with the Nationalpark Hohe Tauern we are currently running a long-term monitoring to better understand the causes and consequences. Recently the ORF (Austrian Broadcasting Corporation) covered our research activities at the Sattelkar (Obersulzbachtal, Salzburg) with a news article and a TV report (German only).
