A low hum in Lithuania, Kumzaiciai

Low frequency, like the car is idle around somewhere Ten years ago my father found a strange narrow hole in the ground behind our house. We tried to measure the depth of it and made a wooden plank of 10 meters, we put it down the hole and couldn't reach the bottom. We discussed with some seismic specialists and they said that it is very similar to man made holes for oil research. House is built in 80's and we don't know what happened there before it was built. There is no oil well near by our village.
