Earthquake? No...Frost Quake!

Well.....You learn something new every day, no matter how old you are. In all my years I never heard of this. What makes it personal is I have family living in N Y , right on the shores of Lake Ontario and they are in the midst of the results of an ice storm and are experiencing these "booms".
