New research by Chris Goldfinger places the probability of the next Cascadia earthquake at about 80% by 2059 Jack Ohman, 1991, The Oregonian Oregon FY08-09 Accomplishments
State of Oregon FY08 NTHMP Grant Overview Total award: $253,910 FY08 Objectives • Initiate tsunami hazard assessment in Bandon, Oregon. • Promote tsunami risk mitigation and preparedness. • Support NWS TsunamiReady program. Oregon FY08-09 Accomplishments
FY08 Objective 1:Bandon Tsunami Hazard Assessment • Tasks Accomplished (1a) Cascadia earthquake source model completed. (1b) Tsunami deposits data compiled for Bandon area. (1c) Unstructured computational grid generated; Over 50 test simulations completed at Bradley Lake; Final inundation runs (30) planned for March 2010. (1d) Project management ongoing; Contributed to NTHMP partnership; Cochair, NTHMP Mapping & Modeling Subcommittee; Preparation of GIS database and final report, spring-summer 2010. Oregon FY08-09 Accomplishments
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 • 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 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 • 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
State of Oregon FY09 NTHMP Grant Overview Total award: $710,992 FY09 Objectives • Complete new generation of tsunami inundation maps for Oregon. • Empower public to prepare for tsunamis and build communities resilient to a broad spectrum of coastal hazards. • Build a sustainable, community-based outreach and education program that supports TsunamiReady. Oregon FY08-09 Accomplishments
FY09 Objective 1:New Tsunami Inundation Maps • Progress on Tasks (1.1.1) Bandon tsunami simulations underway; (1.1.2) Compilation of geologic evidence for prehistoric tsunamis in Bandon area complete; (1.1.3) Project management ongoing; GIS database and final report planned for spring-summer 2010. (1.2.1) Tsunami deposits data compiled for southern OR; (1.2.2) Field checking planned for summer 2010; (1.2.3) Supporting NGDC and CA with development of tsunami deposits database. Oregon FY08-09 Accomplishments
FY09 Objective 1:New Tsunami Inundation Maps • Progress Continued (1.3) Tsunami simulations for southern Oregon coast; (1.3.1) DEM development ongoing; generation of computational grid(s) planned for April-May 2010; (1.3.2) Selected southern Oregon tsunami simulations planned June-July 2010; (1.3.3) Preparation of GIS database and final report planned for fall 2010. Oregon FY08-09 Accomplishments
FY09 Objective 1:New Tsunami Inundation Maps • Issues • Grid resolution limits computational speed • Southern Oregon tsunami simulations delayed to summer 2010 Oregon FY08-09 Accomplishments
FY09 Objective 2:Empower Public to Prepare • Progress on Tasks (2.1) Produce tsunami evacuation maps for 7 coastal communities in southern Oregon (fall 2010). (2.2) Update online tsunami evacuation map (fall 2010). (2.3) Post new data to Tsunami Information Clearinghouse (fall 2010). • Issues • Evacuation maps and update to online data contingent on completing southern Oregon inundation map by fall 2010. Oregon FY08-09 Accomplishments
FY09 Objective 3:Sustainable, Grassroots Outreach • Progress on Tasks (3.1) Identify and support Tsunami Outreach Coordinator (complete). (3.2) Help 3 communities meet TsunamiReady requirements (ongoing progress) (3.3) Contribute to Tsunami Information Clearinghouse (ongoing) (3.4) Identify 3 community organizers (February 2010) (3.5) Coordinate the 2010 Tsunami Road Show (April 2010) Oregon FY08-09 Accomplishments
FY09 Objective 3:Sustainable, Grassroots Outreach • Issues • Unexpected administrative workload delayed contract for Tsunami Outreach Coordinator. • Sensitivities related to selecting target communities. • Fixes • Careful evaluation of target communities and upfront outreach campaign to disseminate Outreach Program information to coastal cities and counties. Oregon FY08-09 Accomplishments
