Pine Bluff, AR: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Pine Bluff is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. That puts Pine Bluff in the 80th percentile nationally for seismic hazard - higher than 80% of the 4,875 US cities USGS was checked against here.

How Pine Bluff compares

The raw figures: peak ground acceleration 0.149g, short-period spectral response 0.292g, 1-second spectral response 0.134g. Among 68 Arkansas cities in this dataset, Pine Bluff ranks 33 for seismic hazard, the 52th percentile within the state. About 38,785 people live in Pine Bluff, Arkansas.

What a retrofit costs in Pine Bluff

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 Pine Bluff address.
