Oregon Coast

Cascadia Subduction Zone

Tectonic Plate Activity

1700 Earthquake

Oregon Coast Demographics Tillamook County  2010 Census  25,250 persons  22.9 persons/mile2  Industry  Agriculture  Tourism  Fishing  Timber Clatsop County  2010 Census  37,039 persons  44.7 persons/mile2  Industry  Manufacturing  Tourism  Trade  Fishing  Timber

Current Inundation Zones  Have been mapped by State of Oregon Department of Geology and Mineral Industries (DOGAMI) since 1994  New generation under development  Considers new science  Local Sources  Distant Sources

Tsunami Sources Local Sources  Originating from Cascadia Subduction Zone  Limited Time to React  Only Warning May be Earthquake  Produces large tsunami Distant Sources  Generated from Distant Source  May Delay Tsunami by 4 hours  May arise from Asian side of Pacific or from Gulf of Alaska  May arise from earthquake that is felt or submarine  Other sources  There may be multiple waves with large time intervals

Clatsop County Current Inundation Zone

Tillamook County Current Inundation Zone

Focus Areas – City of Tillamook

Focus Areas – Cannon Beach

Revision of Inundation Zones  Seeks to use current research and extend the tsunami zone if applicable  Specifically looking at 1700 rupture/tsunami  Can then be used to to identify critical infrastructure  Hospitals  Public Safety Answering Points  Fire Departments  Major Roadways  Alt Routes  Airports / Landing Zones

Literature Search  Literature Search using Penn State Library & Google Scholar revealed 28 pertinent journal articles/conference presentations.  Divided into 3 areas pertinent to this project:  Seismological research into causes and sizes of tsunamis, focusing on the Pacific Coast  Paleo-seismic research into past events that focus on the area in question with the intent of expanding the inundation zone  Emergency Management Approach to Tsunamis

Data Sources  Oregon Spatial Data Clearinghouse  Political divisions  Roads  DOGAMI data  Homeland Infrastructure Foundation-Level Data (HIFLD)  Hospitals  Emergency Assets  Digital Elevation Models  Custom Datasets  Academia

Methodology  Use existing Inundation Zone  Research Estimated Inundation Zone of 1700 Earthquake  Create revised Inundation Zone  Feature Class of Critical Infrastructure (CI)  Identify CI on both zones  Feature Class of Possible Refuge Points  Use Road Network to identify connectivity

Deliverables  Target audience – Emergency Planners & Civic Leaders  Storymap for stakeholders  Comparison of Zones  Location of Critical Infrastructure  Prioritized  Possible Gathering Points  Road Network Connectivity  Reference Maps  Planning & reference

Presentation Venue  Northwest GIS User Conference – Oct 2016  Searching other options  Regional Emergency Management Conferences  Tsunami Research/Planning specific conference
