Description: One of the primary chronic and most devastating geologic hazards in Oregon is landslides. Average annual repair costs for landslides in Oregon exceed $10 million and severe winter storm losses can exceed $100 million (Wang and others, 2002). As population growth continues to expand and development into increased landslide susceptible terrain occurs, greater losses are likely to result. In order to begin reducing losses from landslides, large-scale endeavors are necessary at all community levels from state government to individual family homes. One successful way to reduce losses from landslides is through pre-disaster mitigation, which can be performed at many scales from statewide to local. To begin pre-disaster mitigation of landslides, the landslide hazard must be located. Once the hazard is located the population and infrastructure vulnerable to the hazards can be identified and the risk mitigated. In order to improve our understanding of the landslide hazard in Oregon the Statewide Landslide Information Database of Oregon (SLIDO) was created. The four main objectives of this study were 1) identify previously mapped landslide deposits statewide, 2) improve the understanding of landslide hazards throughout Oregon, 3) improve the abilities of communities to begin effective landslide management and risk reduction activities, and 4) recommend future improvements and updates to the database.The goals of SLIDO Release 2 were 1) update SLIDOr1, 2) improve historically active landslide portion of the database through review of local municipality (city or county) data, 3) compile references that have detailed data on regionally significant or typical landslides, 4) add non-spatial data related to landslides such as landslide type, activity, certainty of identification, process, estimated age, etc. in specified areas, 5) populate and convene an Oregon Framework Implementation Team (FIT) landslide element subcommittee to develop standards for the statewide landslide theme. Also develop the landslide element stewardship standard.

Description: This map uses measured shear wave velocity data, estimated shear wave velocity data from the literature, and geologic data primarily taken from OGDC 5 (Ma and others, 2009, in refernces) and SLIDO 2 (Burns and others, 2011 in references) with some coming from published earthquake hazard studies. The methods and data used to make this map are described in detail in : Madin, I.P., and Burns, W.J., 2013, Ground motion, ground deformation, tsunami inundation, coseismic subsidence, and damage potential maps for the 2012 Oregon Resilience Plan for Cascadia Subduction Zone Earthquakes; Oregon Department of Geology and Mineral Industries Open-File Report O-13-06.

Description: This feature class contains actual and "pseudo" drillholes used to create 3D geologic and geophysical models for the 2013 Portland NEHRP project. Drillhole points were digitized from maps or coordinates in drilling reports for geotechnical or other purposes (e.g. water wells, hydrocarbon exploration, etc). The drillhole feature class participates in two one-to-many relationship classes with tables of downhole geologic interpretations (PDX_NEHRP_interpretations) and shear-wave velocity measurements (PDX_NEHRP_Vs) using the key field "LOG_ID_concatenated".
