Huntertown's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Huntertown in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Huntertown sits at the 42th percentile for seismic hazard among 4,875 US cities.

How Huntertown compares

The raw figures: peak ground acceleration 0.066g, short-period spectral response 0.129g, 1-second spectral response 0.063g. Among 126 Indiana cities in this dataset, Huntertown ranks 82 for seismic hazard, the 35th percentile within the state. About 11,481 people live in Huntertown, Indiana.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Indiana. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Insuring against this, not just retrofitting

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Huntertown address.
