  1. Geodesy- and Geology-Based Slip-Rate Models for the Western United States (Excluding California) National Seismic Hazard Maps

    The 2014 National Seismic Hazard Maps for the conterminous United States incorporate additional uncertainty in fault slip-rate parameter that controls the earthquake-activity rates than was applied in previous...

  2. 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...

  3. 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...

  4. 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...

  5. Lava and Ice Interaction at Stratovolcanoes: Use of Characteristic Features to Determine Past Glacial Extents and Future...

    Structures resulting from lava and ice interaction are common at glaciated stratovolcanoes. During summit eruptions at stratovolcanoes, meltwater is produced and travels freely down steep slopes and thin...

  6. 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...

  7. Earthquake and Tsunami Forecasts: Relation of Slow Slip Events to Subsequent Earthquake Rupture

    The 5 September 2012 Mw 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. High-precision GPS recorded numerous slow slip events (SSEs) in the decade leading up to...

  8. 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,...

  9. 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...

  10. Landslide Velocity, Thickness, and Rheology from Remote Sensing; La Clapiere Landslide, France

    Quantifying the velocity, volume, and rheology of deep, slow-moving landslides is essential for hazard prediction and understanding landscape evolution, but existing field-based methods are difficult or...
