Cryoseism (frost quake) in Indianapolis Feb, 10

Cryoseism is caused by rapid freezing of water (soil-, interstitial-, percolation water) in saturated soil, rock and bedrock.
As the water freezes and expands, it's putting more stress on surrounding rock. This builds up until it's explosively relieved -> loud noise, ground shaking -> cryoseism
Those are mostly very localized events...

Here are some articles of the latest cryoseism in Indiana:
