Whether it's worth purchasing depends on your home's construction type, age, soil conditions, and mortgage requirements. Consult a licensed insurance agent to evaluate your specific risk.

The estimated annual earthquake insurance supplement for a median-priced home ($770,662) in Monmouth County, NJ is approximately $132/year ($11/month).

Standard homeowners insurance (HO-3) policies explicitly exclude earthquake damage in virtually all cases. This includes damage from ground shaking, landslides triggered by earthquakes, soil liquefaction, and aftershocks.

Fire damage that occurs as a secondary result of an earthquake (e.g., from broken gas lines) may be covered under a standard policy, but this varies by insurer.
