Family Safe "That's ALL that Matters". The kids Enjoyed it, their dog is underneath the bed and will not come out.

 

Did any of you hear a rumble first and then felt the quake?

Odd sensation. Minor vibration, then felt like a bulldozer was rolling down the street, then helicopter landing on roof, then "shake, rattle and roll" for about 7-10 seconds then subsided in about 3 seconds. Total elapsed time in DC: about 15 seconds max., but who knows unless you had a stopwatch.

Interesting the USGS can pinpoint the precise location and DEPTH of an earthquake. Are there sensors every mile or something? I don't get how they know with such precision the epicenter and depth.

In all honesty what I really Dislike about D.C.?

 

Damn near anything that ANY of us post in here can be used politically, even it's just for fun.

 

But that's what we ALL get for living in D.C. or near D.C.. ]:)
