Why I think earthquakes are possible in Calgary you mean?

Because they don't just happen along faults. They can happen as a result of volcanic activity and other geologic forces. Not to mention, Calgary is close to the Rockies, which proves there is a lot of recent geologic activity in the area. (Recent on a geologic scale as the Rockies are still forming).

I think the largest earthquake in recorded North American history was actually in Missouri or Kansas back in the pioneering days. Some people estimate it would have been over 10 on the Richter scale. Minnesota and Ontario have been known to get occasion tremors as well.

The last year within 500 k of Calgary there were 17 "events".

I remember when I was a kid in the 80's there was a really mild earthquake somewhere that was felt in Calgary.

I remember that as well. I also felt one here that happened in Pennsylvania about 6 or 7 years ago. It was only a 4.8 or 5.0 on the Richter as well.

The good news for us Albertans in any event is that our winds will push much of the debris south and east. (not that we wouldn't get our share of ash, but much less than if there was no wind and it simply shot in 1000kms each way).

I was wondering if you have any information on the Yellowstone Volcano and the fact that it won't have a really big, damaging one. The reason I am asking is because I was in Australia last year touring the Undara Lava Tubes and the tour guide was a Geology Major and studied volcanoes. He said there were two Mega-Super volcanoes (he used that term, or something like that). One was in Indonesia, and the other was Yellowstone. They would have the energy of 10 000 volcanoes or something ridiculous like that.

Anyways, just wondering where you got your info from.

Nevermind. I did a little search myself and found this article. There was another link to Armaggedononline but I figured BBC might be a little more accurate. Interesting read.

Another really good site.

I like my ground as I like my sadists. Firm and unyielding.

And another one. This one is not quite as alarming as the BBC, saying most scientists believe it will be thousands or hundreds thousands of years before she blows, and there will be decades or centuries of warning.
