US EditionStudy Finds Magnitude 7.5+ Earthquake Potential on Canada's Tintina Fault
YUKON TERRITORY, JUL 29 – Researchers found the Tintina Fault has accumulated six meters of strain in 12,000 years, posing a risk of magnitude 7.5+ earthquakes that threaten Yukon communities and infrastructure.
- This past week, University of Victoria researchers revealed that the Tintina Fault in Yukon Territory poses a significant seismic hazard, confirming repeated large earthquakes in the Quaternary period.
- Having slipped 450 km over its lifetime, the Tintina Fault was believed to be inactive for more than 12,000 years despite being silent for over 12,000 years.
- Using high-resolution topographic data, researchers documented multiple surface-rupturing earthquakes along a 130-kilometer segment of the Tintina Fault, with glacial landforms 2.6 million and 132,000 years old offset by 1,000 m and 75 m.
- Following the study, an earthquake of magnitude 7.5 or greater could severely shake Dawson City and threaten highways and mining infrastructure, with findings to be integrated into seismic building codes.
- Despite its quiet history, the Tintina Fault continues to accumulate strain at 0.2 to 0.8 mm per year and has stored at least 6 meters of unresolved displacement, posing a future earthquake hazard.

Scientists Say A Major Earthquake Fault Line Is Waking Up
High up in Canada’s Yukon Territory, a seismic gun is being cocked and aimed at the little community of Dawson City—population 1,600. If a new study in the journal Geophysical Research Letters is correct, that town or one of many others in the region could be rocked by a major earthquake pretty much at any moment. The source of the danger is a 1,000 km (620 mi.) formation known as the Tintina fault that cuts northwest across the Yukon and termin…

Hidden fault line could lead to ‘catastrophic’ earthquake stretching from US to Canada, scientists warn
Scientists with the University of Victoria in British Columbia, Canada, have warned that the overlooked Tintina fault line could unleash catastrophic earthquakes across North America -- disrupting infrastructure, triggering landslides and impacting thousands of people from Alaska to Montana.
Scientists Warn: Tintina Fault Could Unleash Major Earthquake
A major fault in Canada’s Yukon Territory, long thought dormant, has shown signs of recent seismic activity. A new study from the University of Victoria (UVic) has brought attention to a newly identified seismic threat in northwestern Canada’s Yukon Territory. Stretching approximately 1,000 kilometers, the Tintina fault cuts northwest across the region and has shifted [...]
