Paleoearthquakes Of The Past ~6000 Years At The Dead Mouse Site, West-Central Denali Fault At The Nenana River, Alaska, Joseph K. Carlson

Theses and Dissertations--Earth and Environmental Sciences

The Denali fault (DF) in south-central Alaska is a major right lateral strike-slip fault that parallels the Alaska Range for much of its length. This fault represents the largest seismogenic source for interior Alaska but due to its remote location and difficulty of access, a dearth of paleoearthquake (PEQ) information exists for this important feature. The fault system is over 1200 km in length and identification of paleoseismic sites that preserve more that 2-3 PEQs has proven challenging. In 2012 and 2015, we developed the ‘Dead Mouse’ site, which provides the first long PEQ record west of the 2002 rupture …
