Researchers from the University of Victoria identified fault scarps that suggest major slips occurred during the Quaternary period (2.6 million years ago to present day). Some faults, like the Tintina fault, are believed to be inactive , meaning that they no longer have earthquakes. Researchers found a series of fault scarps passing within 20 kilometers (12 miles) of Dawson City, Canada—evidence that could completely change our understanding of the Tintina fault’s movement. As Finley explained, the Tintina fault may exceed magnitude 7.5, meaning that it would be considered a “major” earthquake on the magnitude scale , and could cause major damage across larger areas. According to the press release, Canada’s National Seismic Hazard Model (NSHM) doesn’t currently recognize the Tintina fault as a discrete seismogenic fault source.
