Interestingly, last night I was up late laying on my couch watching TV and at around 12:30 AM or so, I heard a low boom, more like a rumbling sound and felt a bit of a shake sort of like a big heavy truck had gone right past my house. I felt another rumble a few minutes later. I checked the USGS website when I got up this morning and nothing was reported as far as any earthquakes in my area – York PA and nothing in the local news about any explosions.
I wonder if it was a “frost quake”.

It’s been well below freezing for the last few weeks but then we had a warm up to the mid 50's followed by a rapid drop in temperature below freezing and with snow.
We have been having those in the Midwest too. My wife and I were woke up by, what seemed to be a boom in the back yard. I got up to investigate and just as I laid back down I heard it again. It sounded like somebody dropping something heavy on my deck. But the dog didn't seem to take notice. Still I took her and my .45 down stairs to check things out. The next morning, it was on the news. I have never heard of that before this season.

It was around that time (considering the hour difference CST) when I experienced the same thing living here in central Friendship Adams cty Wisconsin. Intend to check with neighbors to see if they experienced the same thing
Me neither, but we didn't get to define the word, or coin a new one for this phenomena.
