I bought this house (single story, finished two car garage-modern). I noticed cracks and found online that there were 8 earthquakes the last two days, in the lower state I live in . Asking neighbors, only one had a few things fall off the wall, most didn't realize it at all. Maybe house settling?? Cracks along the wall/ceiling joint, coming down the wall near the electrical panel, and new joint cracks on the ceiling. this is all texture and paint. OK, can I Spackle and paint now?? or will it just keeping on cracking?? 4 foot level is not finding anything wrong. fun being a homeowner.
