Vibration  sensor is for detecting a debris flow indirectly and repeatedly by  measuring a ground vibration. Usually sensor is buried in ground near  the torrent. Detected signal can be output to the warning siren device  for evacuation information. In addition, it is possible to estimate  discharge of debris flow by amplitude of vibration.
