GEOPRAEVENT featured on NOVA
Our work with radar-based landslide monitoring was shown in the movie Killer Landslides by NOVA on PBS. See the section about us or the whole movie here:
GEOPRAEVENT in Georgia
On May 17th, 2014, a large ice avalanche detached from the Devdoraki Glacier on the north side of Mt. Kazbek (5033m), causing a large debris flow of several million cubic meters. The debris flow claimed several lives as it blocked an important road connecting Georgia...
Detecting people with radar
This is from a project in the Swiss Alps where avalanches are released artificially using blasting towers. The explosions are controlled remotely. For the safety of backcountry skiers, GEOPRAEVENT has developed a system using radar technology that detects and tracks...

We have updated the timelapse movie for the landslide Val Parghera. The area is still moving constantly:
Ice avalanche at Weissmies
Our radar-based glacier monitoring at Weissmies is operational since more than one month. Several ice avalanches happened during this time. We managed to capture one of them in unprecedented detail: Two days before the failure, locally increased velocities were...
State-of-the-art glacier monitoring
The overhanging tongue of the Trift Glacier presents a potential threat to people on and in the vicinity of the Trift Lake because it could detach from the upper part of the glacier and cause tidal waves in the lake. In order to foresee a possible ice avalanche,...
Radar measurements on hydro dams
Read about our displacement measurements on hydro dams using our interferometric radar system! The newest edition of «Wasser Energie Luft» (in German) features our article on challenges and possibilities offered by such measurements in order to quantify the...
Val Parghera: One year of continous monitoring
Since April 2013, GEOPRAEVENT is monitoring the landslide Val Parghera for the canton of Grisons. The monitoring system consists of several gauge radars, webcams and a weather station. During June 2013, interferometric radar measurements and laser scans have shown...
Rockfall on the Chur-Arosa railway line
A rockfall disrupted the railway line of the Rhaetian Railway close to Lüen on the Chur-Arosa line on October 16, 2013. Fast action was required: Could the railway be cleared from the debris right away or were further events to be expected? Together with the...
Trade fair for safety and security: Special exhibition «Risk management for natural hazards»
From the 12th to the 15th of November we will present our newest projects and developments at the special exhibition for «managing risks posed by natural hazards». Come and see us there! See our Georadar in live action or inspect a trigger line up close! Additionally,...
Plaine Morte: Glacial lake drainage
After weeks of a steadily rising water level, the large glacial lake Faverges on the Plaine Morte glacier drained completely on the 1st and 2nd of august. Our webcam station captured the whole event, as approximately 1.5 mio cubic meters of water seemingly disappeared...
Debris flow monitoring Bregaglia Valley, GR
In late 2011, a huge rock fall from the north face of the Pizzo Cengalo deposited more than 1 mio cubic meters of debris in the Bondasca Valley. Heavy precipitation events in summer 2012 lead to four large debris flows that reached the village Bondo, several...
3rd station in China
Our first station in the Shaksgam Valley has been up and running for two years. In 2012, a second station was added at an altitude of almost 5000 m asl. In May 2013, two members of the GEOPRAEVENT AG team and a geologist from GEOTEST AG travelled to China again to...
