Oregon FY08-09 Accomplishments


Fy08 objective 1 bandon tsunami hazard assessment1

FY08 Objective 1:Bandon Tsunami Hazard Assessment

  • Issues

    • Scheduling conflicts among science team delayed development of earthquake source model.

    • Incorporating new lidar data into computational grid proved more time consuming than expected.

  • Fixes

    • No cost one-year extension granted.

Oregon FY08-09 Accomplishments


Fy08 objective 2 promote tsunami preparedness

FY08 Objective 2:Promote Tsunami Preparedness

  • Tasks Accomplished

    (2a) Attended over 15 outreach and education events;

    Informed ODOT on earthquake and tsunami hazards.

    (2b) Posted interactive tsunami evacuation maps online;

    http://www.nanoos.org/data/products/oregon_tsunami_evacuation_zones/index.php

    Helped Cannon Beach install evacuation map signs.

    (2c) Carried out first annual Tsunami Road Show.

    (2d) Provided technical assistance to Pacific Peril exercise.

    (2e) Produced 8-min Oregon tsunami preparedness video in partnership with USGS.

Oregon FY08-09 Accomplishments


Fy08 objective 2 promote tsunami preparedness1

FY08 Objective 2:Promote Tsunami Preparedness

  • Issues

    • NTHMP Subcommittee co-chairs requested clarification on subtasks 2b – 2e .

    • All subtasks were not explicitly described in FY08 proposal, which led to confusion.

    • Subtasks 2b – 2e contribute to overall outcomes targeted by Objective 2 and support task 2a.

    • Worked with Oregon Tsunami Advisory Council to develop FY09-012 Oregon Tsunami Outreach Program.

Oregon FY08-09 Accomplishments


Fy08 objective 3 tsunamiready support

FY08 Objective 3:TsunamiReady Support

  • Tasks Accomplished

    (3a) Design for Lincoln City blue-lens strobe warning signals complete; installation planned for Jan. 2010;

    Lincoln City renewed TsunamiReady designation.

    (3b) Procured 326 tsunami signs for Tillamook County, Lincoln City, Yachats, and Coos Bay (complete).

  • Issues

    • No cost one-year extension granted to complete both projects.

Oregon FY08-09 Accomplishments
