Risk Overview

Marshall County carries a low composite natural disaster risk, with a National Risk Index score of 56.8 out of 100 — placing it in the 57th 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.

Risk here concentrates in landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $53K in expected annual loss and about 0.73 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $16M in expected annual loss and about 2.29 events per year; and ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Low risk — $116K in expected annual loss and about 0.55 events per year. Across all hazards, FEMA estimates $18M in expected annual loss for a population of 31K.

Beyond physical exposure, Marshall County has a medium social vulnerability rating (how susceptible the population is to harm) and a 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 county's disaster history tells the same story: Marshall County has received 25 federal disaster declarations since 1972, including 10 for severe storm events and 6 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.

Among 55 West Virginia counties, Marshall County ranks #24 for overall natural disaster risk.
