Cascadia Lifeline Programs (CLiP)
Elevation Model
This is a hybrid elevation model which is compiled from 10 meter and 30 meter DEMs. Lidar data from the Oregon Lidar Consortium was downsampled. Data from the USGS National Elevation Dataset were used in the remaining gaps where lidar data were not available.
Geology
This is a complete, digitally compiled, general geology file with a vector polygon format from the Oregon Geologic Data Compilation by DOGAMI.
This is a compilation of quaternary faults within the last 1,600,000 years. The source of this file is from USGS (USGS, 2006) website in a vector polyline structure.
Site Class
National earthquake hazard reduction program which depicts the site class based on the site soil properties and shear wave velocity in accordance with geotechnical data.
SLIDO Database - V3
This is a statewide landslide information database for Oregon a product by The Department of Oregon Geology and Mineral Industries (DOGAMI). In this website we are streaming this files from their server and present them on the interactive map. These are polygon feature datasets representing the landslide deposits and scarps along with scarp flanks.

In this website we are streaming this files from their server and present them on the interactive map.Historic landslides which previously occurred in Oregon are compiled in a feature dataset as these points.
Transportation
This accessibility map presents the travel time from each zone to Portland International Airport when the network is intact. The afternoon peak traffic condition (4pm-5pm) is adopted for simulation in VISUM.
This accessibility map presents the travel time from each zone to Portland International Airport when the network is disrupted, specifically, the eight bridges over the Willamette Rive near Portland downtown are set to be failed. The afternoon peak traffic condition (4pm-5pm) is adopted for simulation in VISUM.
Drillhole Database
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". It is provided by department of Oregon geology and mineral industry (DOGAMI).
Ground Motion
Using developed regression relationships between peak ground acceleration and Modified Mercalli intensity from Wald et al (1999), this continuous raster map is generated to give the users information about how strong the earthquake will be felt.
This map uses bedrock PGA values from the model developed by USGS for a specific secnario of Cascadia subduction earthquake ground shaking in the Pacific Northwest (http://earthquake.usgs.gov/eqcenter/shakemap/global/shake/Casc9.0_expanded_se/) combined with a new map of NEHRP site class for Oregon (Madin and Burns 2013) and uses the soil factor relationships of Boore and Atkinson (2008) to calculate site-dependent PGA. The methods and data used to make this map are described in detail in : Madin, I.P., and Burns, W.J., 2013. Published in a open file report (OSSPAC,2013) by Oregon Department of Geology and Mineral Industries (DOGAMI).
This map uses bedrock one-second spectral amplification (SA01) values from the model developed by USGS for a specific secnario of Cascadia subduction earthquake ground shaking in the Pacific Northwest (http://earthquake.usgs.gov/eqcenter/shakemap/global/shake/Casc9.0_expanded_se/) combined with a new map of NEHRP site class for Oregon (Madin and Burns 2013) and uses the soil factor relationships of Boore and Atkinson (2008) to calculate site-dependent SA01. The SA01 values are then converted into PGV values. The methods and data used to make this map are described in detail in : Madin, I.P., and Burns, W.J., 2013.

Landslide
This map uses the methods of section 4.2.2.2 of the HAZUS-MH MR4 (FEMA, 2011 in references) to create a new coseismic landslide probability map for Oregon. The map uses a new landslide susceptibility map and a new map of site peak ground acceleration from Madin and Burns (2013, in references) as input to the model.
