Quaternary Faults and Folds (QFF)

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. This interactive map displays locations and relative activity of Alaska's faults and folds. The map offers zoom and scroll options, and multiple base map layers. Click individual fault and fold traces to view basic fault parameters: name, age, slip rate, slip sense, dip direction, mapping certainty, and mapped scale. This resource is intended to provide simple and quick means of visualizing structure locations and characteristics. Users must recognize mapping certainty and data accuracy limitations when zooming in farther than the stated mapped scale for a given feature and treat resulting visual representations with appropriate caveats. The structures displayed are replicated from DGGS publications MP 141 (Quaternary) and MP 150 (pre-Quaternary).
