Inside the dam, look, there is a tunnel, the red line, the tunnel.
And here we have people that are working inside the tunnel.
And the task was, with my technique, is it possible to detect the tunnel?
Okay, and we see on the right top, there is the tunnel.
Just to explain you, where you see red, the vibration energy is high, so it's red.
When you see blue, the vibration energy is low, and inside the tunnel, because you have the air, you don't have vibration, so it's low.
And so you see the tunnel.
And so we were also able to detect, slide 39, also the principal facility that are located inside the dam, which are the turbines.
And all the mechanical machines.
This is all the mechanical machines that are located inside.
This is the Gran Sasso.
It's for me very nice because I was born here.
