Summary
Harold Asmis's blog post is about the risk of earthquakes in eastern Canada, specifically Toronto, Ottawa, and Montreal. He claims that these cities have a similar level of risk as Vancouver, despite being further from a subduction zone. He states that the risk of earthquakes in the east would be more widespread than in Vancouver. He argues that these cities should invest in earthquake-resistant infrastructure to minimize potential damage.
This is interesting. Every few years, they come out with a bunch of media stories. I used write heavily on earthquakes, until they all left town. We are in a very boring era, with only clange being interesting.
This time they are doing a "Kobe-style" earthquake, which is formed from the general stresses around subduction zones. All the big cities have a risk to this type of earthquake. I define it as a 'general' 40 cm/s on common soil. It's 80 cm/s on the landfill and filled swamps.
Toronto, Ottawa and Montreal all have the same hazard and risk as Vancouver. It's just a mater of how the 'big dice in the sky' roll. In the East, we have the problem that the '40 zone' would extend much further than in Vancouver,
I'll go with their estimates, mainly old brick buildings. This would be like Christchurch, New Zealand.
If any of these cities wanted to limit economic damage, they would instrument the buildings. I'm working on devices that would be very cheap. You can bring back a building to service, if you see that it hasn't softened at all. Of course, none of this will be done.
ps. the AI summary really guts the article.
ps that summary just makes me want to rip my head off. I'll stop doing it, I don't want to blend in.
