I got to experience three cryoseisms in last 24 hours. This was a totaly new experience for me.
I had had about five inches of sleet with maybe five or so inches of snow on top until a few days ago. It got really warm for a couple days and it rained, so most of it melted and the ground was completely saturated. The temperature then dropped about 35 degrees right after the rain. It has been cold enough since then for the water in the ground to start freezing, expanding, and popping in little mini earthquakes. One was strong enough I could feel the vibration though the floor. They are surprisingly loud.

I'm sure there are tons of how-to guides out there.
