Risk Overview

About Natural Disaster Risk in Marshall County, Indiana

Marshall County's risk remains modest

Marshall County's composite risk score of 41.60 places it in the very low category and runs slightly below Indiana's state average of 45.52. While tornado risk reaches 66.28, other hazards remain relatively contained, resulting in a balanced overall risk profile. Compared to the nation's most hazard-prone counties, Marshall County faces measurably lower natural disaster exposure.

Among Indiana's safer counties

Marshall County ranks in the lower-risk tier statewide, with a composite score of 41.60 that falls below the state average of 45.52. Its risk profile is substantially better than Marion County (97.49) and Monroe County (75.99), reflecting more moderate hazard exposure. Most Indiana counties share similar or slightly higher risk levels than Marshall.

Fairly comparable to surrounding areas

Marshall County's 41.60 score sits close to neighboring Montgomery County (41.00) and Miami County (52.80), reflecting consistent risk patterns across north-central Indiana. The region shares moderate tornado exposure but avoids the extreme earthquake and flood risks seen in counties further south. Adjacent areas show similar preparedness priorities.

Tornadoes are the main concern

Tornado risk dominates Marshall County at 66.28, substantially higher than other hazards and the primary natural disaster threat residents face. Flood risk reaches 44.91, roughly in line with state averages, while earthquake and wildfire risks remain low. Tornado preparedness should be the primary focus for households here.

Focus tornado prep, standard coverage works

Marshall County residents should ensure standard homeowners insurance is current and add a tornado/hail deductible if available to manage wind damage costs. Developing a tornado plan—identifying safe rooms, practicing drills, and staying weather-aware—is more critical than extensive add-on coverage. Given lower flood and earthquake risks, standard policies provide adequate protection for most households.

Risk Verdict

Compared to the nation's 3,144 counties, Marshall County ranks at the 42th percentile for natural disaster risk — toward the safer end of the spectrum. Marshall County's 42th percentile ranking is favorable, though every county carries at least one natural hazard worth knowing — reviewing the specific risks listed above helps households focus their preparedness where it matters most.

Hazard Breakdown

Tornado risk is Marshall County's dominant natural hazard, ranked at the 66th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 54th percentile nationally. Additional tracked hazards include flood (45th percentile), hurricane (32th percentile), wildfire (7th percentile).

Preparedness Context

Tornado exposure at the 66th percentile nationally makes Marshall County a county where a battery-powered weather radio — not just smartphone apps — is a worthwhile household investment, given that mobile networks often fail during severe storms. The secondary earthquake hazard at the 54th percentile nationally adds seasonal complexity to Marshall County's preparedness calendar, since earthquake and tornado risk often peak at different points in the year. In Marshall County, tornado watches indicate favorable atmospheric conditions while warnings mean rotation has been detected — households benefit from understanding this distinction so they shelter immediately on a warning, not after seeking visual confirmation.

Regional Context

Marshall County sits within 3.9 composite points of the Indiana state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
