Risk Overview
Overall natural disaster risk in Auglaize County is very low, with a National Risk Index score of 41.8 out of 100 — placing it in the 42nd national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $1M in expected annual loss and about 0.00 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $614K in expected annual loss and about 3.33 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Low risk — $151K in expected annual loss and about 0.78 events per year. Across all hazards, FEMA estimates $15M in expected annual loss for a population of 46K.
Beyond physical exposure, Auglaize County has a low social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The federal record bears this out: Auglaize County has received 13 federal disaster declarations since 1978, including 7 for severe storm events and 2 for tornado events. The most recent was Tornadoes (tornado), declared in May 2024.
Among 88 Ohio counties, Auglaize County ranks #64 for overall natural disaster risk.
