Washington State:

WA DNR has Landslide, Tsunami, Liquefaction Susceptibility, NEHRP Soil Classes
and Seismic Design Class layers on its Surface Geology data page. This link will take you to there:
WA DNR Hazards & Environmental Geology

Direct links are below:

Liquefaction Susceptibility: definitions found in metadata
NEHRP Seismic Site Class: Definitions can be found in metadata

Tsunami Inundation DNR layer of Tsunami Inundation based on 2 Cascadia Scenarios

Landslide Inventory
WA landslides 1:24,00 Scale: DNR Layer of past landslides

The following info is found at DNR Forest Practices GIS Spatial  Datasets:

Hazard Zones
This layer shows Landslide Hazard Zones by likelihood of Instability.
For mapping, the important field is INTERP_INSTAB_CD. This can be labeled as:

Value: 1 Definition:  low likelihood of instability
Value: 2 Definition: moderate instability potential
Value: 3 Definition: high delivery potential
Value:4 Definition: very high instability potential
Value: 9 Definition: indeterminate instability potential (should be rarely used)
Value: 8 Definition: Variable (landforms of concern)
Value: 0 No Info

The field INTERP_DELIVR_CD should also be considered as its defined as:
"Analyst observed/interpreted ability to deliver debris to a resource or threaten public safety"
The coding for this can be found in the metadata

Forest Practices Landslides A Another DNR Forest database of past landslides

FEMA Floodplains
WA Dept. of Ecology FEMA Digital Flood Data (note: in .eoo format, needs to be converted using arc catalog (make sure ArcView 8x Tools in View>Toolbars is activated then conversion tools>Import from interchange file)


This info found at DNR GIS: Wildfire & Prevention:
DNR Fire Stats 1970-2007
DNR Fire Stats 2008-Present
Wildland/Urban Interface High Risk Communities

DOE Sites of Interest, Tier II Reporters etc.
DOE Facility Site (Ecology Permitted Sites)
Used for mapping hazmat related events and potential sources.
This layer shows a location or operation of interest to Ecology that has an active or potential impact on the environment.
This includes:
  • State Cleanup sites
  • Federal Superfund sites
  • Hazardous Waste Generators
  • Solid Waste Facilities
  • Underground Storage Tanks
  • Dairies
  • Enforcement
