“…Mass movement-generated infrasound signals have specific amplitude and occupy a frequency band from 0.001 to 20 Hz (e.g. Kogelnig 2012). Infrasound can travel thousands of kilometres and remain detectable over such distances.…”

“…To protect one key section of this road, seven avalanche towers (remote controlled avalanche releasing systems working with explosives) were installed on two avalanche paths in 2011, together with a radar unit for avalanche detection at one of this avalanche channels. Additionally, from 2012 to 2014 an infrasound array consisting of five sensors was installed in a forest close to the radar unit Kogelnig et al 2013) and since 2013 the new detection system based on a single infrasound sensor has been also installed there. The detection systems can be principally used for examining the effectiveness of explosions in case of poor visibility and at night, but also for information about spontaneous avalanche activity.…”

Automated detection of snow avalanches is an important tool for avalanche forecasting and for assessing the effectiveness of avalanche control measures at bad visibility. Avalanche detection systems are usually based on infrasound, seismic, or radar signals. Within this study, we compared three different types of avalanche detection systems: one avalanche radar, one infrasound array system consisting of four infrasound sensors, and a newly developed single sensor infrasound system. A special focus is given to the new single sensor system, which is a low cost, easy to install system, originally designed for the detection of debris flows and debris floods. Within this work, we analysed how this single sensor system could be adapted to detect also snow avalanches. All three systems were installed close to a road near Ischgl (Tyrol, Austria) at the avalanche-exposed Paznaun Valley. The valley is endangered by two avalanche paths which are controlled by several avalanche towers. The radar system detected avalanches accurately and reliably but was limited to the particular avalanche path towards which the radar beam was directed. The infrasound array could detect avalanches from all surrounding avalanche paths, however, with a higher effort for installation. The newly tested single infrasound sensor system was significantly cheaper and easier to install than the other two systems. It could also detect avalanches form all directions, although without information about the direction. In summary, each of the three different systems was able to successfully detect avalanches and had its particular strengths and weaknesses, which should be considered according to the specific requirements of a particular practical application.

“…The event EWS for debris flows usually detects the passage of a debris flow at a certain cross section where the sensor is installed, but they may also be able to detect some tens of seconds in advance the arrival of the debris flow when ground vibration sensors are employed Koschuch et al, 2015;Schimmel and Hübl, 2015). The event EWS that rely on the use of algorithms to process the monitoring data and recognize the occurrence of a debris-flow event, usually require long development and systematic testing.…”

Abstract.A permanent field installation for the systematic test of debris flow warning systems and algorithms has been equipped on the eastern Italian Alps. The installation was also designed to produce didactic videos and it may host informative visits. The populace education is essential and should be envisaged in planning any research on hazard mitigation interventions: this new installation responds to this requirement and offers an example of integration between technical and informative needs. The occurrence of a debris flow in 2014 allowed the first tests of a new warning system under development and to record an informative video on its performances. This paper will provide a description of the installation and an account of the first technical and informative results obtained.
