Frost Quake ???

[Entropy]

The Weather Network website is reporting on Frost Quakes happening again last night.

 

I'm not so sure about these Frost Quakes. One person reports in their report says they thought someone fell out of bed upstairs. Last night I heard a boom/bang twice. Once sounded like my daughter fell out of bed, the other time I was standing in the kitchen and the boom was above my head. Could it be the roof trusses contracting, or the plywood on the roof, or something like that?

 

My house is 120 ft from the shore Lake Scugog and I am used to booms from expanding lake ice, which come through the ground, both last night felt like they were on or in the roof.

 

Thoughts?

I have heard it many times over the years when it's been really frigid like this. Usually its the wood frame of the house, or the sideing cracking in the cold. Dad used to say it was some of the nail heads popping off. I hope he was wrong
