Strong-Motion Records of the 2002 Denali Fault, Alaska, Earthquake
The M W 7.9 Denali Fault earthquake on 3 November 2002 ruptured a 340-km section along the Susitna Glacier, Denali, and Totschunda faults in central Alaska. The earthquake was digitally recorded at more than 55 strong-motion sites throughout the state at distances up to 280 km from the fault rupture...
