Skyquakes are unexplained phenomena emanating from the sky, soun- ding like a sonic boom. They have been heard in several locations around the world and have been described as being like distant but inordina- tely loud thunder, while there are no clouds in the sky large enough to generate lightning. The phenomenon has been described in Romagna as an incredibly loud roar coming from the Apennine Mountains, crea- ted by a violent wind or by overwhelming water movement underneath the surface of the earth. The sound has apparently vanished and is no longer audible.

In the Apennines there is a deep and endless barrage in which a dolphin has been enclosed for millennia. Every now and then the dolphin becomes nostalgic for the sea; it then shakes itself against the wall of its cage and complains: the squashed water and the screams become a hundred echoes that roll down the cliffs, crossing the whole plain, until finally greeting the long-desired routes hidden in the ocean waves.

In the bright sky, and without the slightest motion, there is an unrestrained shout. At first it is dark, underground, enclosed; then it expands, with extended, descending modulation. At the beginning, it has the power of an earthquake’s rumble, and then it fades into the loud voice of the wind, always with a deep, low tone. It is rare for the modu- lation to rise once again before disappearing, and it is rare for the first enclosed tone to persist without disclosing the highest tone. Something ungraspable characterises this sound. I heard it one night; it was as if it came from the mountains. It ruined my sleep – the sound ran into the immense shadows and reached the borders of silence. It sounded like the violent blasts of wind that scream loudly when entering the caves in the Apennines, making the whole mountain range resonate.
