Summary

Over the past 15 years, Global Positioning System (GPS) technology has been frequently used as a tool to detect potential earth mass movements and to track creeping landslides. In this study, we investigated 4 years of continuous GPS data (September 2006–July 2010) recorded at a landslide site in Alaska. This GPS station (AC55) was installed on an un-identified creeping site by the Plate Boundary Observatory (PBO) project, which was funded by the US National Science Foundation. The landslide moves with a steady horizontal velocity of 5.5 cm/year toward NEE 15° and experiences a steady subsidence of 2.6 cm/year. There is a considerable correlation between annual snow loading and melting cycles and seasonal variations in the landslide [...]
