The Tintina fault stretches 1,000 kilometers (621 miles) across northern Canada, crossing the Yukon and ending in Alaska.

The new study reveals more recent activity along the Tintina fault, which stretches about 600 miles, from northeastern British Columbia into Alaska

Seismic pressure is building along the Tintina fault line, stretching from Canada's Yukon Territory to Alaska.

A major fault in Canada’s Yukon Territory, long thought dormant, has shown signs of recent seismic activity. A new study from the (UVic) has brought attention to a newly identified seismic threat in northwestern Canada’s Yukon Territory.

The Tintina fault hasn’t produced a large earthquake in 12,000 years, but that could soon change, researchers warn.
