New London, WI: what USGS's seismic model says

New London carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts New London in the 8th percentile nationally for seismic hazard - higher than 8% of the 4,875 US cities USGS was checked against here.

How New London compares

The raw figures: peak ground acceleration 0.025g, short-period spectral response 0.051g, 1-second spectral response 0.037g. Among 157 Wisconsin cities in this dataset, New London ranks 120 for seismic hazard, the 24th percentile within the state. About 7,524 people live in New London, Wisconsin.

Retrofit economics for New London

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

Insuring against this, not just retrofitting

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 New London address.
