The driving idea of this work was to design a detection system for different kinds of alpine mass movements which is low cost and can be easily installed. These requirement leads to a combination of one infrasound sensor and one geophone which are placed co-located and a microcontroller where a specially designed detection algorithm is executed which can detect mass movements in real time directly at the sensor site. This detection system can be extended to a warning system which can be used for different applications:
Protection of infrastructure like traffic lines by controlling a traffic light, information about events to check the status of technical protection measure (e.g. fill level of a retention basin or debris flow net), protection of construction sites inside the channel (e.g. for cleaning up a basin after an event), or at regions where a temporary protection is sufficient.
Further this system offers first information of the process-type and a rough estimation of the peak discharge and the total volume. These values are calculated from the seismic and infrasound signals.
