These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Data points represent head scarps, flank scarps, and minor internal scarps (linear) associated with landslide deposits in the Little North Santiam River Basin, Oregon. This work was completed as part of the Master's thesis "Turbidity Monitoring and LiDAR Imagery Indicate Landslides are Primary Source of Suspended-Sediment Load in the Little North Santiam River Basin, Oregon, Winter 2009-2010" by Steven Sobieszczyk, Portland State...
Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited. The development of robust and transportable models requires access to numerous inventories of ground failure triggered by earthquakes that span a broad range of terrains, shaking characteristics, and climates. We present an openly accessible, centralized earthquake-triggered ground-failure inventory repository in the form of a ScienceBase Community to provide open access to these data, and help accelerate progress. The Community hosts digital inventories created by both USGS and non-USGS authors. We present...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This layer is an inventory of existing landslides deposits in the Little North Santiam River Basin, Oregon (2009). Each landslide deposit shown on this map has been classified according to a number of specific characteristics identified at the time recorded in the GIS database. The classification scheme was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009). Several significant landslide...

This inventory was originally created by Okuyama and others (2013) describing the landslides triggered by the M 9.1 Tohoku-Oki, Japan earthquake that occurred on 2011-03-11 at 05:46:24 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological...
An FY17 NGGDPP grant funded a demolition project to rescue of 1952+ core boxes from a collapsed building, the Cary Annex. The OTHER Undocumented Core Collections (OUCC) defined herein helps compile the interim results of an inventory of 781 of the 1952+ rescued boxes, funded by an FY21 NGGDPP grant. As a result of the inventory, 277 core boxes were identified that are associated with 63 new, previously undocumented boreholes. All of the boxes were damaged and likely need reboxing; 85 were reboxed by NCGS staff. Some of the core boxes have partial losses of core lengths; some material is weathered in situ (in the box). These collections include HARD ROCK and TRIASSIC geologic core samples. Coordinate data is not...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geodatabase is an inventory of existing landslides in the Little North Santiam River Basin, Oregon (2009). Each landslide feature shown has been classified according to a number of specific characteristics identified at the time recorded in the GIS database. The classification scheme was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009). Several significant landslide characteristics...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Data points represent locations of photographs taken of landslides in the Little North Santiam River Basin, Oregon. Photos were taken in spring of 2010 during field verification of landslide locations (deposits previously mapped using LiDAR-derived imagery). The photographs depict various landslide features, such as scarps, pistol-butt trees, or colluvium deposits. This work was completed as part of the Master's thesis "Turbidity...
An FY17 NGGDPP grant funded a demolition project to rescue of 1952+ core boxes from a collapsed building, the Cary Annex. This update on the status of the Legacy Core and Cuttings Collection (LCCC) helps compile the interim results of an inventory of 781 of the 1952+ rescued boxes, partly funded by an FY21 NGGDPP grant. As a result of the inventory, 504 core boxes were identified that are associated with 42 original borehole records in the LCCC. For the same borehole records, 367 core boxes remain palletized in conexes, or were damaged or lost. All of the core boxes were damaged and likely need reboxing; 120 were reboxed by NCGS staff. Some of the core boxes have partial losses of core lengths; some material is...
