A video was uploaded to Reddit this weekend of weird sounds in the skies above Puerto Rico! In the video, you can hear what sounds like fireworks or explosions, however there’s NOTHING visible on film.
This isn’t the first time a strange occurrence like this has happened. The same noise has been heard over the skies of North Carolina, New York and Virginia, and is often referred to as ‘Seneca Guns.’
According to the Coastal Review Online, “USGS has long researched phenomena around the Outer Banks sometimes called ‘Seneca guns,’ but they say it’s just a name, not an explanation.”
The phenomena of ‘Seneca guns’ refer to booms that have been “heard and felt along the shores of Lake Seneca and Lake Cayuga in New York State, as well as the tidewater area of Virginia, the Outer Banks and along the Carolina coast.”
The USGS says there’s no agreement on a cause for Seneca guns, with most cases never explained.
