1959 M7.5 earthquake, on the Rocky Mountain Front. I never studied this earthquake because it just caused landslides, and was in the middle of nowhere. Still, it shows that the whole front is probably active and that Banff and such should be aware of it.
These are pure 'active displacement' earthquakes, like the San Andreas. If you had regional GPS stations installed, you would notice some action that supported the direction of faulting for this earthquake. The intraplate earthquakes around our place are 'stress relief' earthquakes, and show no regional displacement. This gets scientists greatly confused.
