The files consist of two types: tabulated data files and graphical map files. Data files consist of six .csv files, representing six experiment dates (2016_06_14, 2016_16_15, 2016_18_15, 2016_16_21, 2016_16_22, 2016_16_23). Each of these files contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity measured at that time (e.g., flow depth, pore pressure, normal stress, etc.). Map files consist of six .pdf files, each representing an experiment date listed above. The maps show the thickness of the sediment deposited onto the runout pad after each experiment. Sediment thickness was determined using photogrammetery software from Adam Technology.

The files consist of two types: tabulated data files and graphical map files. Data files consist of three .csv files, representing three experiment dates (2017_05_23, 2017_05_24, 2017_05_25). Each of these files contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity measured at that time (e.g., flow depth, pore pressure, normal stress, etc.). Map files consist of three .pdf files, each representing an experiment date listed above. The maps show the thickness of the sediment deposited onto the runout pad after each experiment. Sediment thickness was determined using photogrammetery software from Agisoft.

The data presented in this data release represent the records from a rain gage near Black Hollow, CO, a watershed that is tributary to the Cache La Poudre River. On 20 July 2021 a large rainstorm moved over the watershed and generated a large debris flow that destroyed several homes, resulting in four fatalities. The watershed had been burned prior to the rainstorm during the Cameron Peak wildfire (13 August – 2 December 2020). Here we present time-series data the Dry Creek rain gage, which captures the storm that triggered the Black Hollow debris flow. Latitude and Longitude data are included in the header. The timezone of the timestamp is in Mountain Standard Time, note that the storm occurred when the local...

This data release includes time-series data and qualitative descriptions from a monitoring station on a steep, landslide-prone slope above the City of Sitka, Alaska. On August 18, 2015, heavy rainfall triggered around 60 landslides in and around Sitka. These landslides moved downslope rapidly; several were damaging, and one demolished a home on South Kramer Avenue and killed three people. On September 16-18, 2019, the U.S. Geological Survey installed instrumentation at a site near the initiation zones of these landslides and other previous landslides on the west face of Harbor Mountain. The station consists of an electronics enclosure, a mounted rain gage, and two instrumented soil pits. Instruments record continuous...

This data release comprises a georeferenced raster layer depicting the estimated susceptibility to intense rainfall-induced landslides in Puerto Rico, which is a supplement to: Hughes, K.S., and Schulz, W.H., 2020, Map depicting susceptibility to landslides triggered by intense rainfall, Puerto Rico: U.S. Geological Survey Open-File Report 2020–1022, 91 p., 1 plate, scale 1:150,000, https://doi.org/10.3133/ofr20201022. Users of this layer are strongly encouraged to read the text herein and available with Open-File Report 2020-1022. DEVELOPMENT OF THE LANDSLIDE SUSCEPTIBILITY MAP Landslides commonly occur in Puerto Rico during or soon after intense rainfall and present significant hazards to the built environment...

The files consist of six .csv files, with two files for each of three experiments (2017_05_16, 2017_05_17, 2017_05_18). One of the two files contain high-resolution data (1000 Hz) collected during the period of slope failure only, and the other files contain low-resolution data (10 Hz) for the entire duration of an experiment. Each of these files contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity measured at that time (e.g., flow depth, pore pressure, normal stress, etc.). In addition, 289 pairs of images were extracted from two video cameras during the sediment failure on May 17 2017. First posted - April 24, 2019 (available from author)...
