“...Now have you ever heard of a “cold boom”? Technically known as a cryoseismic boom, this phenomenon is reserved only for the coldest of temperatures, and considered pretty rare for the lower latitudes of the continental United States. The boom sound is created by a cryoseism, which is a mini explosion within the ground caused by the rapid expansion of frozen water....”

According to the same story from AP that has been ruled out.
“There are some stories going around that’s what it was, but based on the research we’ve done here, it doesn’t appear what people heard is related to the cryoseism phenomena,” Day told The Norman Transcript. “There’s not enough moisture, and the temperatures are not cold enough. That happens in areas where you have a lot of water flowing through a lot of rock,” Day said.”
This happens with trees too. It gets so cold the water in the tree freezes and expands, splitting the trunk. I walked through a wooded area last winter and all you could hear was the wood cracking. As it was night the whole thing was kinda creepy.

The freeze depth in the soil in this part of the world is a couple of inches at most.
I was reading an interesting book on how the sudden drop in temperatures linked to the ice ages correlates well with the timing of magnetic reversals of the Earth’s magnetic core.
When the core is reversing, it alters the flow of magma, triggering more eruptions and earthquakes. We know the ash thrown up by volcanic activity can cool the Earth. Add that on a large scale with the extra precipitation it causes and the sunlight reflected back to space, and you get an ice age.
The magma shifts could also explain why Oklahoma and now Texas are seeing a lot of little quakes but hadn’t previously; lots of reports blame fracking, but not all of the areas have fracking wells right there.
Ten major volcanoes have erupted along the Ring of Fire during 2012-2013. It may be related to the shifting magnetic poles. It is not related to “climate change” as some have blamed it, saying that melting glaciers release so much pressure on the continental plates that faults shift and eruptions occur.
I heard something like that on an extremely cold night many years ago. I opened the door to look out because I could hear noises from the plant two miles away when “BOOM”!
I thought something had blown up and expected to hear the warning sirens from the plant go off. Nothing. The plant continued to operate and nothing was said about any explosions anywhere near the town.
The Norman Transcript ran an article yesterday from a National Weather Service meteorologist that discounted cryoseismic boom because the ground was not wet or cold enough.
With this cold snap sounds like logic.
