00:00For decades, scientists thought the Tintina Fault in Canada's Yukon was dormant.
00:04But new research just changed that story, and it's raising alarms.
00:08Stretching over 1,000 kilometers, the Tintina Fault has been silent for over 40 million years.
00:14Or so we thought.
00:15Now, thanks to satellite and drone technology,
00:18scientists have found clear signs of ancient earthquakes right near Dawson City.
00:23They've discovered fault scarps, huge cracks left behind by powerful quakes,
00:27that reveal the Tintina Fault has been active during the last 2.6 million years.
00:32Some landforms are offset by up to 1,000 meters.
00:36And even more shocking, scientists believe the fault could unleash a quake larger than magnitude 7.5.
00:43That's enough to cause intense shaking, landslides, and major damage to roads and mining operations.
00:49The scary part? There hasn't been a large quake here for 12,000 years.
00:53And that could mean pressure is building.
00:55Experts are now pushing to update Canada's seismic hazard maps and emergency plans.
01:00Because the next big one might be closer than anyone realized.
