National Tsunami Hazard Mitigation Program Strategic Plan 2018-2023

"The success of the National Tsunami Hazard Mitigation Program is built upon the model of scientists and practitioners working collaboratively on behalf of states, territories, and stakeholders. The program’s 2018-2023 strategic plan advances its mission and vision through goals and strategies that strengthen tsunami preparedness, mitigation, mapping, modeling, and warning coordination."
 

DOGAMI Open-File Report O-16-08, Local tsunami evacuation analysis of Warrenton and Clatsop Spit, Clatsop County, Oregon

DOGAMI released new "Beat the Wave" (BTW) modeling and evacuation route analysis for the communities of Warrenton and Hammond. The map figures depict minimum pedestrian evacuation speeds needed to stay ahead of the wave for two levels of increasing evacuation difficulty: 1) all bridges intact, 10-minute delay from start of earthquake before starting evacuation, and 2) only retrofitted bridges intact, 10-minute delay. The BTW maps are important for evaluating mitigation options such as evacuation route improvement, the establishment of wayfinding signage, land use planning actions, and helping to guide the establishment of vertical evacuation structures. Similar work is currently underway at Rockaway Beach in Tillamook County and is expected to be completed early in 2017.
 

DOGAMI Open-File Report O-15-02, Local tsunami evacuation analysis of Seaside and Gearhart, Clatsop County, Oregon

This report evaluates the difficulty of pedestrian evacuation of Seaside and Gearhart, Oregon, in the event of a local tsunami generated by an earthquake on the Cascadia subduction zone (CSZ). The map plates depict minimum evacuation speed needed to stay ahead of the wave for three levels of increasing evacuation difficulty: 1) all bridges intact, 5-minute delay from start of earthquake before starting evacuation, 2) only retrofitted bridges intact, 5-minute delay, and 3) only retrofitted bridges intact, 10-minute delay.
