2002 M7.9 Denali Fault Earthquake

 

 

The largest inland earthquake in North America in almost 150 years struck Alaska on November 3, 2002. It ruptured three different faults ending with a total rupture length of ~210 miles (340 km). This was one of the most impactful earthquakes in interior Alaska. While the fault rupture lasted for approximately 100 seconds, its effects were felt for many days.

The M7.9 Denali Fault event was preceded by the M6.7 Nenana Mountain earthquake on October 23, 2002. Its epicenter was located on the Denali fault 22 km east of the M 7.9 event epicenter.
