Risk Overview
About Natural Disaster Risk in Tillamook County, Oregon
Tillamook faces moderate-to-high national risk
Tillamook County's composite risk score of 81.33 and Relatively Moderate rating exceed the U.S. average considerably. The coastal location and seismic setting combine to produce above-average hazard exposure.
Tillamook ranks among Oregon's higher-risk counties
At 81.33, Tillamook County's composite score markedly exceeds Oregon's 63.43 state average, placing it in the state's upper tier. The county faces above-average flood, earthquake, and wildfire exposure.
Riskier than neighboring coastal counties
Tillamook's score of 81.33 surpasses adjacent Clatsop and Yamhill counties' composite risks. The combination of coastal geography, winter precipitation, and seismic hazard creates particularly elevated exposure in Tillamook.
Floods and earthquakes dominate Tillamook
Flood risk reaches 76.34, driven by Pacific winter storms, coastal drainage, and rainfall; earthquake risk scores 95.45 due to Cascadia Subduction Zone proximity. Wildfire (43.58) poses a secondary but growing concern.
Flood and earthquake coverage critical
Tillamook residents should prioritize flood insurance—essential for anyone near coastal or lowland areas—and obtain earthquake riders on homeowners policies. Neither is typically included in standard coverage; combined, they add 15–25% to your policy cost but provide vital protection.

Hazard Breakdown

Preparedness Context
Tillamook County ranks at the 95th percentile nationally for earthquake risk. Unlike most natural hazards, earthquakes provide no advance warning; preparedness here means structural adjustments and a practiced response, not alert monitoring. Flood at the 76th percentile nationally is a separate hazard dimension for Tillamook County that requires different protective strategies from earthquake preparedness. For earthquake preparedness, Tillamook County's county emergency management office often maintains a list of community water supply points, Red Cross shelter locations, and post-quake assistance programs — useful resources to identify before an event occurs.
Regional Context
Compared to other Oregon counties, Tillamook County runs 17.9 composite risk points higher than the state mean — reflecting above-average hazard concentration in this area.
