Hi Abby.

I read a little while ago that one was felt in Colorado and was the biggest they'd had for a number of years- I think it was a 5.3.

Washington D.C. seems a bit far away for you to have felt the same one, but perhaps it was related?

I'm sure everything will be fine, but any small quake is a good reminder to review your emergency plans, coordinate with your family, etc.

Take care,
