Risk Overview
Logan County carries a low composite natural disaster risk, with a National Risk Index score of 79.2 out of 100 — placing it in the 79th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Most of Logan County's expected losses come from landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $51K in expected annual loss and about 1.36 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $27M in expected annual loss and about 1.82 events per year; and wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $400K in expected annual loss and about 0.01 events per year. Across all hazards, FEMA estimates $30M in expected annual loss for a population of 32K.
Beyond physical exposure, Logan County has a high social vulnerability rating (how susceptible the population is to harm) and a very low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
The county's disaster history tells the same story: Logan County has received 36 federal disaster declarations since 1967, including 16 for severe storm events and 10 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 55 West Virginia counties, Logan County ranks #5 for overall natural disaster risk.
