Does Rushville, IN need an earthquake retrofit?

Rushville carries Seismic Design Category B under USGS's ASCE 7-16 model. 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 Rushville sits at the 52th percentile for seismic hazard among 4,875 US cities.

Rushville by the numbers

The raw figures: peak ground acceleration 0.087g, short-period spectral response 0.17g, 1-second spectral response 0.081g. Among 126 Indiana cities in this dataset, Rushville ranks 48 for seismic hazard, the 62th percentile within the state. About 6,208 people live in Rushville, Indiana.

What a retrofit costs in Rushville

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 Rushville address.
