Toronto booms may be frost quakes

Article

Even more mysterious is that some people reported hearing booms at other times during the day as well, ranging from 2 p.m. to 6 p.m. to 1 a.m. on Christmas morning.

That's what the news is reporting, but I think it was too widely felt for that.  Even the news people can't wake the seismic people!  There were way too many booms, and frost quakes are always single events.

The source of one frost quake was discovered in the northern US, and was a surface buckle of rock.  That makes sense, it is what we call a pop-up.  We all must try to wake up the seismic people, and especially the infra-sound people to get a full list of the events.

Update:  Article   Apparently, these ice quakes have hit in a great group before.  Ice quakes would be locatable with the seismic network, if there were somebody to look at them.  Perhaps we should all raise money on Kickstarter?

More booms this morning (Monday). Widely reported on Twitter and Facebook and reasonably time coordinated across southern Ontario. Wonder if any of the seismic monitors show anything around 5:30 am EST? Sounded like something big landed on the roof in Peterborough.

They are saying more of these frost quakes happened this morning, I thought it was just our deck doing some frost dancing, was loud enough to jar me out of a pleasant dream at 3am

Heard them, too. I wish CBC could rouse somebody in Ottawa.
