Simulation of Near-Fault Seismic Ground Motions of 03 November, 2002 Denali Earthquake Using Modified Semi-Empirical Approach
An effective earthquake (Mw 7.9) struck Alaska on 3 November, 2002. It ruptured 340 km along three faults namely, the Susitna Glacier, Denali and Totschunda faults in central Alaska. The earthquake was recorded at 23 stations in Alaska and the Peak Ground Acceleration (PGA) of 0.32g was recorded at...
