Claremont, NH: what USGS's seismic model says

Claremont carries Seismic Design Category B under USGS's ASCE 7-16 model. 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 Claremont sits at the 61th percentile for seismic hazard among 4,875 US cities.

Claremont by the numbers

The raw figures: peak ground acceleration 0.138g, short-period spectral response 0.245g, 1-second spectral response 0.069g. Among 13 New Hampshire cities in this dataset, Claremont ranks 12 for seismic hazard, the 8th percentile within the state. About 13,105 people live in Claremont, New Hampshire.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Claremont 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 Claremont address.
