October 12, 2026 - GIS Maps and services may be down or experiencing slow loading times. DOGAMI staff are working to address the issue, but we do not yet have an ETA on a fix.
Interactive Maps
DOGAMI's interactive maps, GIS data, and map services help Oregonians better understand our state's geology and geologic hazards.
Hazards
HazVu, Oregon Statewide Geohazards Viewer shows landslide, flood, tsunami, coastal erosion, earthquake shaking, fault, and volcano geohazards.
Landslides
SLIDO, Statewide Landslide Information Database for Oregon, shows landslides that have been identified on published maps.
Oregon Tsunami Explorer
The
Oregon Tsunami Explorer allows the user to visualize tsunami evacuation zones developed for Oregon.
Lidar Data
Lidar Data Viewer shows shaded relief imagery for Oregon.
Geology
Geologic Map of Oregon shows the incredible variety of rock types that make up our state.
Minerals
MILO, Mineral Information Layer for Oregon, shows information regarding mineral occurrences, prospects, and mines.
Geothermal
GTILO, Geothermal Information Layer for Oregon,
shows features of thermal springs and wells and direct-use areas.
Mining Permits
Permit Viewer shows mine site locations and information, including downloadable permit files.
Mount Hood
Mount Hood Multihazard Viewer shows the intersection of geologic hazards and community assets.
DOGAMI interactive maps provide general information about Oregon's geology and geologic hazards and are not intended to be used for site-specific planning or to replace site-specific investigations.
GIS Data and Services
Geospatial data for download and web map services maintained by DOGAMI. Specialty software is needed to download data and use map services.

| Tsunami | The Oregon Tsunami Geospatial Compilation, release 1 (OTGC-1.0), includes a comprehensive collection of tsunami modeling data produced by DOGAMI from 2011 to 2021. The compilation includes evacuation zones, runup elevations, and wave arrival times for both a local Cascadia source (XXL) and distant Alaska source earthquake. Other datasets include additional inundation zones, flow depths and currents for multiple scenarios.
