Sellersburg's Seismic Design Category, explained

Sellersburg carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Sellersburg sits at the 69th percentile for seismic hazard among 4,875 US cities.

How Sellersburg compares

The raw figures: peak ground acceleration 0.099g, short-period spectral response 0.199g, 1-second spectral response 0.098g. Among 126 Indiana cities in this dataset, Sellersburg ranks 33 for seismic hazard, the 74th percentile within the state. About 10,057 people live in Sellersburg, Indiana.

What a retrofit costs in Sellersburg

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 Sellersburg address.
