Mystery of loud humming noise heard over city What was it?: No one seems to have seen what caused the humming sound over parts of Hull and Holderness in the early hours of this morning.
Mystery surrounds the source of a loud "humming" noise heard by Hull residents last night. The Mail has received several calls from readers from across the city who heard the noise at about 2am. Some have speculated the noise was caused by a low-flying military aircraft. But Damien Elvin, spokesman for the Ministry of Defence, said it was not aware of any military aircraft in the area.
"Something entirely new to us is causing this hum. Its frequency suggests something is 'twisting' the surface of the crust."
The frequency of the new signal suggests something is "twisting" the surface of the crust in some way, says Widmer-Schnidrig. When released, the crust swings back and forth because of its elasticity.
