Scottsburg's Seismic Design Category, explained

Scottsburg 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. That puts Scottsburg in the 70th percentile nationally for seismic hazard - higher than 70% of the 4,875 US cities USGS was checked against here.

Where Scottsburg sits in Indiana

The raw figures: peak ground acceleration 0.102g, short-period spectral response 0.201g, 1-second spectral response 0.095g. Among 126 Indiana cities in this dataset, Scottsburg ranks 28 for seismic hazard, the 78th percentile within the state. About 7,413 people live in Scottsburg, 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.

What this means for insurance

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 Scottsburg address.
