Skyquake

A skyquake is a phenomenon where a loud sound is reported to originate from the sky. It often manifests as a banging, reoccurring thunderous rumbles (where no storms are active), sonic boom from jet engines (where there are no signs of aircraft), or a horn-like noise. The sound may cause noticeable effects on buildings, including vibration in ceilings or across the walls of a particular room. Those who experience skyquakes typically do not have a clear explanation for what caused them. As a result, they are sometimes perceived as mysterious or supernatural. They have been heard in several locations around the world, typically in areas close to lakes and other bodies of water. Reports of skyquakes have come from the North Sea, the Ganges, Canada, Colombia, Japan, Finland, Vanuatu, Australia, Italy, Ireland, India, The Netherlands, Norway, Tierra del Fuego in Argentina, the United Kingdom, the United States, Mexico, Malaysia (particularly Ipoh) and Indonesia (particularly Jakarta and Java).
