Extreme Cold Causes 'Earthquakes'

Article

Not really earthquakes, but 'quake-like impressions'. Trees can explode, ice on the lake cracks, the ground can rupture, roofs can shift, etc.

The interesting side comment is that a Magnitude 6.3 earthquake, which can happen under Hamilton, at the same odds of any other place, will only cause brick siding damage. I think it would cause a lot more damage, especially on the swamps, and where the 'fist' hits.
