Thank you Adair1965 for adding to my knowledge pool. I had never heard of frost quakes till I read your post. I researched it on the Internet and it seems that those in Ontario and area get these quakes because of all the water (Great Lakes, St.Lawrence River etc.) and rock. We get the bitterly cold weather here but nothing that causes these quakes. Closest we would have here is the ice cracking while out on the lake ( I was ice fishing a few years ago when the ice cracked so loud and close that I made a quick exit off the lake).
Put an extra log on the fire, bundle up - we only have 3 more months to go.
