Emergency Assessment of Post-Fire Debris Flow Hazards

Topographic map of post-fire debris flow

Estimates of the probability and volume of debris flows that may be produced by a storm in a recently burned area, using a model with characteristics related to basin shape, burn severity, soil properties, and rainfall.

Map and model input and output data covering N 40.0 40.375 and W 105.25 105.625 in the northern Colorado Front Range for analysis of debris flow initiation resulting from the storm of September 9 13, 2013

Rainfall on 913 September 2013 triggered at least 1,138 debris flows in a 3430 km2 area of the Colorado Front Range. Most flows were triggered in response to two intense rainfall periods, one 12.5-hour-long period on 1112 September, and one 8-hour-long period on 12 September. Data in this project pertain to an area bounded by N 40.0 40.375 and W 105.25 105.625 which includes many of the areas wh

Map data and Unmanned Aircraft System imagery from the May 25, 2014 West Salt Creek rock avalanche in western Colorado

On May 25, 2014, a rain-on-snow induced rock avalanche occurred in the West Salt Creek Valley on the northern flank of Grand Mesa in western Colorado. The avalanche traveled 4.6 km down the confined valley, killing 3 people. The avalanche was rare for the contiguous U.S. because of its large size (54.5 Mm3) and long travel distance. To understand the avalanche failure sequence, mechanisms, and mob

Landslide Monitoring

Monitoring is essential to predicting the behavior of landslides and forecasting which storms can trigger landslides. Graphs showing the most recent data are updated regularly with update cycles ranging from 15 minutes to 24 hours. Landslide monitoring data and information provided on this web site are preliminary and have not been reviewed for accuracy; therefore the data are subject to revision.

Data related to a ground-based InSAR survey of the Slumgullion landslide, Hinsdale County, Colorado, 26 June 2010-1 July 2010

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 displ
