Description:
Collection of rock avalanche case histories where the fragmented rock material overran sediments, including cases where the sediment was mobilized into a mass flow during the event. Impact areas have been mapped and basic descriptive attributes were collected for each case. Events in this dataset include prehistoric events (maximum age approximately 8300 years before present) up to modern events. The events included in this dataset have been described previously in literature, but not combined into a single dataset with consistent descriptions of the coarse, rocky deposits and the sediment mass flows (if present). The data was used in the development of empirical relationships to estimate the runout distance and impact area for both the coarse, rocky debris and sediment mass flows stochastically for potential future events. The event description methodology, the data format and bibliography for case histories are described in the "Rock avalanche impact area data description and sources" file included. This methodology and data format are proposed as a template for the description of an expanded global dataset of events to be compiled. Spatial data is provided as shapefiles, which can be viewed within DesignSafe using the QGIS application within the Workspace.

GIS mapping of the total area impacted primarily by coarse, rocky debris from rock avalanches (defined as Zone 1 deposits), as well as the total area impacted by sediment mass flows resulting from the rock avalanche events (defined as Zone 2 deposits). The data collected utilized published mapping, aerial and satellite imagery, topographic data, and terrain analysis.

Shapefiles of the polygons associated with each Zone 1 and Zone 2 impact area for the rock avalanche events in the dataset (note there is one '.shp' file containing the Zone 1 and Zone 2 geometries for each of the events in the dataset, the other files are all associated with the .shp file when loaded in a GIS program). Additional descriptive attributes are included to describe path topography, substrate material, source zone geology, and the uncertainty around event timing, as described in Mitchell et al (in review), with a read-me file included for quick reference, including a bibliography for the individual case histories is provided.
