  1. Slope Failure Detection through Multi-temporal Lidar Data and Geotechnical Soils Analysis of the Deep-Seated Madrone...

    Landslide hazard assessment of densely forested, remote, and difficult to access areas can be rapidly accomplished with airborne light detection and ranging (lidar) data. An evaluation of geomorphic change by...

  2. Constraining the Holocene Extent of the Northwest Meers Fault, Oklahoma Using High-Resolution Topography and Paleoseismic...

    The Meers Fault (Oklahoma) is one of few seismogenic structures with Holocene surface expression in the stable continental region of North America. Only the ~37 km-long southeastern section of the ~55 km long...

  3. Rock slope stability studies in Siskiyou National Forest

    The line mapping method of Piteau and Martin (1977) was tested on two different rock type road cuts in the Siskiyou National Forest, and was found to be an efficient means of collecting geological data for rock...

  4. Real-Time Change and Damage Detection of Landslides and Other Earth Movements Threatening Public Infrastructure

    Geologic hazards such as coastal erosion, landslides, seismic loading, etc. constantly threaten public highway construction and maintenance. Repeat surveys using terrestrial laser scanning (TLS, ground-based...

  5. Predicting Landslides in Real Time

    The Oregon Department of Transportation, or ODOT, has an ongoing struggle to maintain public highways against earth movements such as erosion, earthquakes and landslides. An earthquake or landslide can close...

  6. Mapping of Unstable and Potentially Unstable Slopes in Sogne og Fjordane

    For the past three years NGU has worked on 25 unstable and potentially unstable rock slopes in Sogn og Fjordane. In addition Fjærlandsfjord, Hyenfjord and Årdalsvatnet were systematically mapped for deposits...

  7. A Preliminary Investigation of the Land Use Limitations of the Major Landforms Along a Portion of the Lincoln County Coast,...

    This study of a portion of Oregon's Lincoln County coast describes the physical limitations to land use of the various landforms in the study area. Seven major landform types comprise the study area: beaches,...

  8. Seaside, Oregon, Tsunami Pilot Study : Modernization of FEMA Flood Hazard Maps

    FEMA Flood Insurance Rate Map (FIRM) guidelines do not currently exist for conducting and incorporating tsunami hazard assessments that reflect the substantial advances in tsunami research achieved in the last...

  9. Probabilistic Tsunami Hazard Assessment at Seaside, Oregon, for Near- and Far-Field Seismic Sources

    The first probabilistic tsunami flooding maps have been developed. The methodology, called probabilistic tsunami hazard assessment (PTHA), integrates tsunami inundation modeling with methods of probabilistic...

  10. Appendix C—Deformation Models for UCERF3

    This document describes efforts to best characterize seismogenic deformation in and near California. The rate of hazardous earthquakes in California is expected to be proportional to deformation rates; in...
