Hot Springs, AR: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Hot Springs 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. Rank it against the rest of the country and Hot Springs sits at the 72th percentile for seismic hazard among 4,875 US cities.

Where Hot Springs sits in Arkansas

The raw figures: peak ground acceleration 0.12g, short-period spectral response 0.236g, 1-second spectral response 0.11g. Among 68 Arkansas cities in this dataset, Hot Springs ranks 38 for seismic hazard, the 45th percentile within the state. About 37,971 people live in Hot Springs, Arkansas.

Retrofit economics for Hot Springs

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Arkansas. 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 Hot Springs address.
