  • Preferred: Yes
  • Start time: 23/11/2015 00:00:00
  • End time: 23/11/2015 03:00:00
  • Noise variability type:  
  • Frequency range min: 0.1
  • Frequency range max: 15
  • Band instrument: HH
  • Note: At first the station was inside a cave, later it has been moved out for safety issues. In the current position, outside the cave, traces are very noisy: this is probably due to the wind, which acts on the parabolic antenna and solar panels, which transmit vibrations to the sensors compartment. The result consists in two anomalous peaks at 7.5 and 13.5 hz
