Abstract
Geologic and seismic data reveal a set of parallel, active, strike-slip faults in east-central Alaska between the Denali and Tintina fault systems. The faults strike northeast to north-northeast, at a high angle to the bounding dextral fault systems, and exhibit sinistral slip. We hypothesize that this set of faults divides the crust into long blocks that are rotating clockwise in response to northerly compression resulting from Pacific–North American plate convergence. We suggest that these faults have produced most of the large historical earthquakes in east-central Alaska between the Alaska Range and the Yukon River.
