New research is sounding the alarm about a major geological fault in the Yukon capable of triggering earthquakes of 7.5 magnitude or more.

Known as the Tintina Fault , it has built up structural strain that could lead to a large quake within our lifetime, according to researchers at the University of Victoria. They published their findings earlier this month in the journal, Geophysical Research Letters. The UVic team was led by Ph.D student , Theron Finley.

The fault stretches about 1,000 kilometres from British Columbia to Alaska . It was once thought to be inactive for at least 40 million years — since before the last ice age ended. Now scientists say it has a history of large ruptures within the last 2.6 million years and could do so again.
