Russellville, AR: what USGS's seismic model says

Russellville 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. Nationally, Russellville ranks above 74% of the 4,875 cities in this dataset for seismic hazard - the 74th percentile.

How Russellville compares

The raw figures: peak ground acceleration 0.142g, short-period spectral response 0.275g, 1-second spectral response 0.122g. Among 68 Arkansas cities in this dataset, Russellville ranks 34 for seismic hazard, the 51th percentile within the state. About 29,442 people live in Russellville, Arkansas.

What a retrofit costs in Russellville

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 Russellville address.
