Tintina Fault
The Tintina Fault is a large right-lateral strike-slip fault in western North America, extending from Flathead Lake, Montana to the centre of the U.S. state of Alaska.[1] It represents the Yukon continuum between the Rocky Mountain Trench in the northern United States and the Kaltag Fault in Alaska.[2]
Unlike the Denali Fault, which ruptured a 200 km (120 mi) portion of its central segment during the 2002 Denali earthquake, the Tintina Fault is considered inactive. Despite this classification, researchers noted a magnitude 5.3 right-lateral event in 1972 and a relatively young (Holocene) 14 km (8.7 mi) scarp with a maximum offset of 2.5 m (8 ft 2 in).[3]
