World premiere: avalanche radar

The world’s first avalanche radar of its kind is up and running in Zermatt.


Online data portal

Our online data portal shows live data and past events.


Motion sensors

Lower maintenance costs for rockfall protection barriers as well as increased safety due to alarm functionalities.


High resolution cameras

Live and past images with a resolution of up to 40 megapixel.
Get insights of the
 hazard zone via the online portal.


Rockfall radar

More than 1 km range and a coverage of 1 km². All-weather suitability.



The interferometric radar detects smallest movements and acts as early warning system for rock instabilities and permafrost.


Cleft measurements

Extensometers and telejointmeters measure clefts with submillimeter precision. Easy and fast installation.


Level measurements

Radars, laser measurements and pressure probes provide useful data about the flow.


People radar

The radar detects people in the hazard zone. In all weather conditions and during day and night. Alerts are triggered automatically.


Innovative Technology

We use cutting-edge technology only to develop our alarm and monitoring systems.

Alpine Installation

All our staff are experienced mountaineers and are trained to work with ropes and helicopters.

Alarm and Monitoring

Our servers monitor the stations and show live data. We alert reliably by priority SMS, email or phone calls. Roads are closed automatically.

Early Warning: Alarm or Warning System?

Climate change affects natural hazards and will cause more frequent and severe natural disasters in the future (SwissRe, 2014). Alpine regions are expected to face an increase in permafrost melting, floods, debris flows, rockfall and avalanches that can cause serious...

Finding the optimal monitoring location

Monitoring moving objects and natural hazards remotely is becoming more and more frequent. Remote sensing technologies make it possible to monitor large areas from a distance and avoid sending people into a hazardous area. Radars – like for example Geopraevent’s...

Who’s talking?

“The monitoring system works very well. The interferometric radar predicted several glacier detachments a couple of days in advance. Thanks to the avalanche radar we are able to keep running our train operations as the radar would stop our trains in a save place in case of a larger detachment.”

Jürg Lauper
Head of Infrastructure
Jungfraubahnen AG

“The system works very well! It supports us in monitoring the road Taesch-Zermatt. Every single avalanche movement in the area is shown which let’s us assess the situation a lot better.”

“I am totally excited about the system. The avalanche radar is always running, even after an avalanche. In the past, it always took a while to replace trigger lines.”

Bernhard Arnold
Head of Safety Department
Municipality Zermatt

“Geopraevent is a strategic partner in developing solutions for avalanche detection. Geopraevent’s radar know how in the area of natural hazards is worldwide unique.”
