If you're both living very near to each other are you sure there isn't some sort of non-seismic explanation, such as an explosion at a factory, a train derailment, a sonic boom, etc.? I think if it were truly an earthquake, even one very deep below the surface, it would be felt throughout NoVA.

If it wasn't an earthquake, I don't know what it was. I suppose there could have been some testing going on at Fort Belvoir. Normally, that is more like a boom than a rumbling.

Maybe it was a sonic boom. But I thought those were loud.

I live in Chantilly -- near Fair Lakes Shopping Center and we definitely felt it. So did at least two of my neighbors.

The whole house shook -- I thought a car had run into the garage.

I'm surprised there is nothing on tv about it.

I was doing a job at the Kingstowne Kohl's at that time - didn't feel anything.

I heard a weird, loud noise also. Not sure what time, but the kids were still at school. I ran to the door expecting to see a big truck on my street but there was nothing. I did think "earthquake" but I didn't feel any movement. What was that!!

I really like the cool link!

I thought it was an earthquake because it felt the same as the one in Annandale last summer. But - who knows? Very mysterious....

I remember strip mines. There was one you'd sometimes see when landing at Dulles, kind of near 50 or 29 I guess and the other around Occoquan. Blasting is closely regulated but far from perfect. They're allowed to rattle windows, just not break them. Maybe it was a blast that got a little on the high side.

A sonic boom can definitely shake a house, and it could be soft too as your distance from the source increased. The pressure wave would evenly disperse though, so I'd expect something like that to make local news. The Navy's Blue Angels were practicing in Canada one year. One of the aircraft was a little off timing and when he added power to make up the difference he broke the speed of sound right over the high rise downtown area. It shattered many windows.
