Our house shakes and sways for an instant almost every day (it feels like a car just ran into it) and we're worried it may one day collapse. Any suggestions as to what it could be? How to get it to stop? or how to find out what it is?
Our house shakes/trembles quite drastically almost every day accompanied by rattling windows, and what sounds like a loud thud on the walls. On the second floor, you can feel a brief (and notable) sway. It honestly feels like a car just hit the house; and then nothing.
It is an instantaneous, one-time thud/shift/tremor that is the closest thing I've felt to the minor earthquakes we used to get in Texas (but we live in Northern Maryland and don't get them here).
We live in a somewhat rural neighborhood on 1 acre with neighbors reporting similar (but possibly less extreme) shaking. There are no mines nearby (probably not blasting) or fracking and you cannot hear it from outside the home as far as we know.
Does anyone have any suggestions as to what this might be and how to stop it? We've lived here for 5 years and it has always occurred. We are worried our house may one day collapse. There are lots of new paint cracks on adjacent wood pieces from the original remodel 5 years ago, likely from the shifting.
We have a finished basement and the foundation (I believe) is poured concrete. The house is a 2 story + attic 1996.
