Turns out, a massive fault line in northern Canada that’s been snoozing for 12,000 years might not be as harmless as we thought. Scientists just found evidence it’s had some serious quakes in the past—and it could do it again. The Tintina Fault is long, hidden, and could pack a punch over magnitude 7.5. It’s not even on Canada’s official earthquake risk map yet. Time to rethink what we know about “quiet” faults! #Science #earthquake #Canada
