Appleton, WI: what USGS's seismic model says

Appleton 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. Rank it against the rest of the country and Appleton sits at the 8th percentile for seismic hazard among 4,875 US cities.

Where Appleton sits in Wisconsin

The raw figures: peak ground acceleration 0.025g, short-period spectral response 0.053g, 1-second spectral response 0.037g. Among 157 Wisconsin cities in this dataset, Appleton ranks 110 for seismic hazard, the 30th percentile within the state. About 75,344 people live in Appleton, Wisconsin.

Retrofit economics for Appleton

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.

Earthquake insurance for a Appleton 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 Appleton address.
