Risk Overview

About Natural Disaster Risk in Morrow County, Oregon

Morrow County risks well below national average

With a composite risk score of 26.37, Morrow County ranks as Very Low—significantly safer than the typical U.S. county. This score reflects a county where most hazards pose minimal threat, though wildfire remains an exception worth monitoring.

Among Oregon's safest counties

Morrow County's composite score of 26.37 places it well below Oregon's state average of 63.43, making it one of the state's lowest-risk counties. Only a handful of Oregon counties experience comparable safety levels across multiple hazard types.

Safer than surrounding counties

Morrow County's score of 26.37 substantially undercuts nearby Gilliam, Wheeler, and Sherman counties, which face higher composite risks. The county's relatively arid geography and sparse development contribute to lower overall exposure compared to neighbors.

Wildfire is Morrow's primary hazard

Wildfire risk scores 91.95—nearly the highest in the county—reflecting the dry grassland environment typical of Eastern Oregon. Earthquake risk (57.92) poses a secondary concern, though flood and tornado threats remain minimal.

Prioritize wildfire coverage now

Standard homeowners policies often exclude wildfire damage; Morrow County residents should verify coverage or purchase a separate policy. Given your county's very low overall risk, basic earthquake and flood riders may provide sufficient protection at reasonable cost.

Preparedness Context

At the 92th percentile nationally for wildfire risk, Morrow County households benefit from creating defensible space — a buffer of reduced vegetation around structures — and reviewing whether homeowners insurance covers wildfire damage in this region. Alongside wildfire, earthquake at the 58th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Enrolling in the county's wireless emergency alert system and keeping a vehicle at least half-full during peak fire season are low-cost habits that dramatically reduce evacuation lag time for Morrow County residents.

Regional Context

Morrow County falls 37.1 points below Oregon's typical county risk level, making it one of the safer natural-hazard environments in the state.
