Stress trajectories across the Northeast Alaska Range

GEOPHYSICAL INSTITUTE UNIVERSITY OF ALASKA, FAIRBANKS, ALASKA 99701

Abstract

A single earthquake on the southeast portion of the Denali fault in 1981 and two earthquake swarms occurring in 1981 and 1984 on the northern flanks of the Alaska Range south of Fairbanks indicate that the axis of maximum horizontal compressive stress is oriented in a NW-SE direction in the region. This is in accord with earlier findings by Nakamura et al. (1980) that tectonic trends signal a similar orientation of maximum horizontal compressive stress trajectories here.
