The Alaska earthquake was a subduction zone megathrust earthquake caused by an oceanic plate sinking under a continental plate. The view shows the approximate location of the epicenter of the magnitude 67 earthquake that occurred in the early morning of October 23 2002. The fault responsible was the Aleutian Megathrust a reverse fault caused by a compressional force.
79 ALASKA EARTHQUAKE November 2002 Denali Fault. Shortly after midday on November 3 2002 a magnitude 79 earthquake ruptured the Denali Fault in the rugged Alaska Range about 90 miles south of Fairbanks. The 2002 M79 Denali fault earthquake resulted in 340 km of ruptures along three separate faults causing widespread liquefaction in the fluvial deposits of the alpine valleys of the Alaska Range.
FAIRBANKS Alaska CNN -- A major earthquake struck 75 miles south of Fairbanks cracking roads crumbling support mechanisms for the trans-Alaska. The 2002 Mw 79 Denali Fault earthquake Alaska provides an unparalleled opportunity to investigate in quantitative detail the regional hillslope mass-wasting response to strong seismic shaking in glacierized terrain. Breakage to this pipeline would cause damages worth hundreds of millions of dollars.
The fault trace passes beneath the pipeline between the 2nd and 3rd slider supports at the far end of the zone. The shaded-relief image above shows the location of the earthquake which occurred on the Denali fault.

The November 3 2002 M 79 central Alaska earthquake occurred as the result of shallow strike-slip faulting within the Alaska Range mountains of the North America plate several hundred kilometers northwest from the Alaska-Aleutian Trench that marks the bathymetric expression of the PacificNorth America plate boundary.

The 2002 Denali Fault earthquake Mw 79 is the largest strike-slip earthquake in North America in more than 150 years. 2006b that allow us to infer rheologic properties of the central and southern Alaskan. The Denali fault earthquake sequence began with the moment magnitude MW 67 Nenana Mountain earthquake on 23 October 2002 Fig.
It started on the previously unrecognized Susitna Glacier Thrust fault a splay fault south. Trace of the Denali Fault after the 79 magnitude earthquake of 3 November 2002 Alaska USA. This caused much of the uneven ground which is the result of ground shifted to the opposite elevation.
The 2002 Denali Fault Alaska earthquake and four years of contin- ued postseismic deformation were well recorded with campaign and continuous GPS data eg. An intense earthquake struck central Alaska about 90 miles south of Fairbanks at 112 pm. The largest inland earthquake in North America in almost 150 years struck Alaska on November 3 2002.
Richter Magnitude 79 3-4 from same EQ The November 3 2002 magnitude M 79 Denali Fault earthquake was the strongest ever recorded in the interior of Alaska.
