Avalanche Detection Overview

Temporary protective measures against avalanches have grown enormously in importance over the past few years. Compared to permanent constructional mitigation measures, today controlled-release of avalanches in small portions from the avalanche fracture zones are being introduced increasingly. Modern remote-controlled blasting installations allow triggering even during snowfall or in the night if necessary. Naturally, with this benefit, the requirements for detection systems that are independent of visibility for verification of successful blasting are also increasing. Furthermore, when avalanches are registered, alarms can be set off and transport routes blocked with traffic lights as well as general information collected about avalanche activity, which could give important indications for avalanche warning.

Thanks to technological advances in recent years, reliable and low-maintenance systems for monitoring and alarming are available.

We offer different avalanche detection systems. There are systems for specific and exact monitoring of individual avalanche paths (LARA), systems for pure verification directly close to the blasting installation (SARA) and monitoring of larger areas form a central location (IDA).

The new platform for integrated display of different detection systems (PIA) gives the avalanche commission a simplified overview as a basis for decision-making.
