Bryan, OH: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Bryan is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Bryan sits at the 47th percentile for seismic hazard among 4,875 US cities.

How Bryan compares

The raw figures: peak ground acceleration 0.073g, short-period spectral response 0.139g, 1-second spectral response 0.058g. Among 254 Ohio cities in this dataset, Bryan ranks 82 for seismic hazard, the 68th percentile within the state. About 8,601 people live in Bryan, Ohio.

Retrofit economics for Bryan

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

Earthquake insurance for a Bryan 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 Bryan address.
