The evacuation zones are the local and distant tsunami scenarios shown on the tsunami evacuation brochures which can be found on the Oregon Tsunami Clearinghouse web site: www.oregontsunami.org
The local tsunami evacuation zone is equal to the XXL tsunami scenario. The distant tsunami evacuation zone is equal to the AKMax tsunami scenario. DOGAMI modeled 7 tsunami scenarios altogether; 5 local tsunami events (S, M, L, XL, and XXL) and 2 distant tsunami events (AK64 and AKMax). These are the worst case scenarios for a local and distant earthquake/tsunami event. These polygons represent the evacuation zones for the entire Oregon coast.
All 7 tsunami scenarios, along with a text report and other supplemental files, can be found in DOGAMI publication: OFR O-13-19, Summary of Tsunami Hazard Data for Oregon.
