Geophysical Research Letters. Within it, the researchers contend that the Tintina fault, which extends approximately 600 miles into Alaska from the northeastern area of British Columbia, has displayed indications of emerging from its inactive period. The fault line is believed to have last exhibited activity nearly 40 million years ago.
The primary worry here is that if the fault line is indeed becoming active, it could potentially trigger an earthquake with a minimum magnitude of 7.5, according to the research. Consequently, the Tintina fault “presents a significant, hitherto unacknowledged, seismic risk,” the authors of the study state.
