I've seen this thread, http://ask.metafilter.com/76193/Why-is-my-apartment-rattling
, but I wanted to ask myself and see if anyone had any further perspectives.
I'm in a three-story building (second floor) and I first noticed it shaking a bit in the middle of the night maybe a year ago. Lately it seems to have become worse, though -- I'm feeling it right now, for example, as I sit and type. It's a bit disconcerting! (Yes, we had an earthquake a couple of weeks ago. That may have made me more acutely aware of vibrations, but this certainly didn't start then.)
It's happening in the summer, so I don't think it's the central heat. We are within a few blocks of a subway line and the Brooklyn-Queens Expressway, so maybe that's it. And there's construction nearby. But it really seems to happen at intervals on its own -- various times during the day, middle of the night, etc. The building's old-ish and already has a slant of a degree or two that I had assumed from was from the foundation settling back after it was first built.
Anyway: It's beginning to drive me nuts. When it happens (as it is now), I kind of get put into a mild state of alarm and get completely distracted from whatever I'm doing (a problem, since I work from home).
Any thoughts about what's going on? Is the building going to come crashing down? Can I get on the landlord's case?
