The Denali fault is perhaps the most significant crustal fault in
Alaska. It is seismically active, has a record of Holocene offset, and
arcs through Alaska, slicing the rugged Alaska Range and bounding the
precipitous north face of Mt. McKinley, the highest peak in North
America. An Mw 6.7 earthquake on the Denali fault on 23 October 2002 was
followed by an Mw 7.9 earthquake on the same fault on 3 November 2002.
The latter earthquake is one of the largest strike-slip earthquakes ever
to strike the United States. Prior to this sequence, the largest
historical earthquake on or near the Denali fault occurred in 1912. The
seismic behavior of the Denali fault, like the northern and southern
segments of the San Andreas fault in California, is characterized by
infrequent large earthquakes. This session will present preliminary
findings on the earthquake seismology, aftershocks, deformation, and
geologic effects of the earthquake. The session also welcomes
contributions that relate to historical seismicity, deformation, and
paleoseismology of this part of the fault. This session is cosponsored
by the Geodesy and Tectonophysics sections.
Abstracts will be accepted for this late-breaking session until 4:00
