Risk Overview

About Natural Disaster Risk in Hunterdon County, New Jersey

Hunterdon County has below-state-average risk

Hunterdon County scores 78.69 for composite disaster risk, earning a relatively low rating and sitting well below New Jersey's state average of 90.81. This positions it as one of the safer counties in the state despite still facing meaningful hazard exposure.

Among the safer counties in New Jersey

Hunterdon County ranks as the lowest-risk county in this dataset, with a composite score of 78.69 compared to the state average of 90.81. This 12-point gap reflects notably lower exposure to major disaster types across the county.

Significantly safer than surrounding areas

Hunterdon County (78.69) is considerably less risky than Morris County (92.88) to its east and Mercer County (95.36) to its south. Its lower composite score is driven by reduced wildfire and tornado exposure compared to more populated neighbors.

Flooding and earthquakes remain concerns

Despite lower overall risk, Hunterdon County still faces notable flood risk at 86.77, driven by river systems and regional precipitation patterns. Earthquake risk scores 75.51, though wildfire risk (26.34) and tornado risk (51.43) are substantially lower than state averages.

Don't skip insurance despite lower ratings

Even in lower-risk Hunterdon County, flood insurance is essential since flooding causes significant damage and standard homeowner policies exclude it. Review your earthquake and windstorm coverage annually, and maintain emergency supplies for the hazards that do affect the region.

Additional tracked hazards include hurricane (75th percentile), tornado (51th percentile), wildfire (26th percentile).

Preparedness Context

With flood ranked as the primary hazard at the 87th percentile nationally, Hunterdon County households should build a go-bag that includes important documents, medications, and supplies to sustain the family for at least three days if evacuation is needed. Secondary earthquake exposure at the 76th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. A waterproof container for documents (insurance policies, ID, prescriptions) and a clear household communication plan for when phone networks are congested are the two highest-value low-cost preparedness steps for Hunterdon County households.
