USGS Mendenhall Postdoc: Exploring Fault Slip Modes in Alaska and the  
Aleutian Arc

We seek a postdoctoral Fellow to study ‘slow’ to ‘fast’ fault slip in  
Alaska and along the Aleutian arc, which are home to a 2500 km span of  
subduction zone and one of the world’s most prominent volcanic arcs.  
These major plate boundaries have hosted episodes of aseismic slip and  
tremor and an extraordinarily high rate of large earthquakes,  
providing the opportunity to examine directly spatial and temporal  
connections between slow slip and earthquakes. Moreover, traversing  
Alaska and the Aleutian arc samples subduction beneath oceanic,  
transitional, and continental lithosphere of varying ages, permitting  
exploration of the range of physical properties under which these  
processes occur.  The Fellow’s research will quantify the occurrence  
and extent of tremor using the seismic networks of the Alaska Volcano  
Observatory (AVO) and the Alaska Earthquake Information Center. The  
Fellow also may investigate ties between tremor and aseismic slip,  
earthquakes, volcanic activity and deep subduction zone processes  
using Plate Boundary Observatory and AVO GPS data, and other data  
types. The Fellow may participate in scientific preparations for the  
2015 arrival of NSF’s USArray and complementary Flexible Array and  
other studies, NSF’s GeoPRISMs program, and Integrated Ocean Drilling  
Program drilling along the northern-most Aleutian trench in 2012.

The Duty Station is Anchorage or Seattle.  Applicants must have a  
Ph.D. or an equivalent degree.  Research Advisors include Stephanie  
Prejean and Peter Haeussler (USGS Volcano Sci. Ctr., Anchorage AK);  
Joan Gomberg (USGS Earthquake Sci. Ctr., Seattle WA); Doug Christensen  
and Jeffrey Freymueller (Univ. of Alaska, Fairbanks AK).  Contact  
Stephanie Prejean, sprejean at usgs.gov or Joan Gomberg,  
gomberg at usgs.gov.  For program information see http://geology.usgs.gov/postdoc/ 
.  APPLICATIONS DUE February 21, 2012.
