Data related to a ground-based InSAR survey of the Slumgullion landslide, Hinsdale County, Colorado, 26 June 2010-1 July 2010
Description
We performed a ground-based, interferometric, synthetic aperture radar (InSAR) survey of the Slumgullion landslide located in Hinsdale County, Colorado. The survey was performed 26 June 2010-1 July 2010 and utilized the IBIS-L InSAR system developed by IDS Corporation. Radar measurements were supplemented by hourly in-situ displacement, pore-water pressure, and rainfall measurements. In-situ displacement was measured using electronic cable extension transducers (extensometers) at three locations and GPS surveying at one location. Pore-water pressures were measured at three locations using electronic vibrating-wire pressure transducers (piezometers). Rainfall was measured at one location using a tipping-bucket rain gage. Georeferenced InSAR data were obtained as cumulative line-of-sight displacement of points on and off of the landslide, and in-situ displacement data were obtained as cumulative displacement parallel to the radar line of sight. InSAR data were obtained continuously (hourly) throughout the survey period while in-situ data were obtained sporadically but generally on an hourly basis.
These data are associated with a study described in Schulz, W.H., Coe, J.A., Ricci, P.P., Smoczyk, G.M., Shurtleff, B.L., and Panosky, J., 2017, Landslide kinematics and their potential controls from hourly to decadal timescales: Insights from integrating ground-based InSAR measurements with structural maps and long-term monitoring data: Geomorphology, doi:10.1016/j.geomorph.2017.02.011.
