No. 52: Jul-Aug 1987
"Residents of North Carolina's southeastern coast call it the 'Seneca Guns' and say it's caused by chunks of the continental shelf dropping off a cliff under the Atlantic Ocean.
"'You will feel the house kind of shake and windows rattle,' said Walt Workman, assistant chief of police in Long Beach. 'It sounds a lot like a sonic boom type of thing.'
"The rumbling boom with a sound like artillery fire is heard along North Carolina's southernmost beaches, sometimes as often as once or twice a week, and scientists can't explain the phenomenon. The sounds have been heard as far north as Fort Fisher, located just north of Cape Fear."

Comment. The real Seneca Guns are, of course, in New York, where they have been heard for years about Lake Seneca. Category GSD, in Earthquakes, Tides, Unidentified Sounds, provides numerous examples of such waterguns, from all around the world. Information about this book may be found here.
