Shelbyville, KY: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Shelbyville in Seismic Design Category C: 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. Nationally, Shelbyville ranks above 68% of the 4,875 cities in this dataset for seismic hazard - the 68th percentile.

How Shelbyville compares

The raw figures: peak ground acceleration 0.082g, short-period spectral response 0.169g, 1-second spectral response 0.09g. Among 79 Kentucky cities in this dataset, Shelbyville ranks 41 for seismic hazard, the 49th percentile within the state. About 18,048 people live in Shelbyville, Kentucky.

Retrofit economics for Shelbyville

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

Earthquake insurance for a Shelbyville home

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 Shelbyville address.
