Approximately 11pm - Give or Take - on July 4th, Our Residence began to Quiver.
There was a Sound that Sounded Like the Front Windows Rattling...
But Neither the Mild Shaking nor the Window Sounds were Constant and They didn't seem to correspond with each other.
The Whole Experience Lasted Less than 3 minutes and Apparently was so Mild that I was the Only one that Noticed.
I was Able to Catch Part of the Last Few Rattling Sounds.
I've Boosted the Volume In Places of the Video to Over a 200% Increase. Even with the Volume Boosted, I Still had to Turn Up My Television to 25 to Hear the Specific 'Tapping' Like Sound.
THE SOUND THAT WAS OCCURRING WITH THE PREVIOUS HOUSE QUIVERING STARTS IN THE VIDEO AROUND 28 SECONDS INTO THE RECORDING & NO LONGER OCCURS AFTER 34-ISH SECONDS MARK.
I DIDN'T CATCH THE HOUSE CONTENTS SLIGHTLY VIBRATING, ONLY THE SOUND COMING FROM THE WINDOWS.
* IT WAS NOT ANY TYPE OF FIREWORKS. ANY TYPE OF FIREWORKS HAD CEASED AT APPROXIMATELY 10:00 p.m.
* THE HOUSE IS NOT LOCATED ANYWHERE NEAR TRAIN TRACKS OR AN AIRPORT.
So, The Only Logical, Physical Explanation is that there was a Tremor.
I Haven't Heard Any Local News Reports Confirming This...
But... I Do Live on a Fault Line.
