Service Description: The Alaska Division of Geological & Geophysical Surveys (DGGS) has designed a Quaternary fault and fold database for Alaska in conformance with standards defined by the U.S. Geological Survey for the National Quaternary Fault and Fold Database. Alaska is the most seismically active region of the United States; however, little information exists on the location, style of deformation, and slip rates of Quaternary faults. Thus, to provide an accurate, user-friendly, reference-based fault inventory to the public, DGGS created a GIS shapefile of Quaternary fault traces and compiled attributes that describe age, relative activity, and general parameters for each fault or fold. This report describes relevant information pertaining to the shapefile and online access and availability. The database is the first comprehensive digital compilation of Quaternary faults in Alaska and future updates will include the results of new research, as well as summary sheets describing each fault.
