Lisbon, WI: what USGS's seismic model says

Lisbon 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. That puts Lisbon in the 18th percentile nationally for seismic hazard - higher than 18% of the 4,875 US cities USGS was checked against here.

Where Lisbon sits in Wisconsin

The raw figures: peak ground acceleration 0.035g, short-period spectral response 0.073g, 1-second spectral response 0.047g. Among 157 Wisconsin cities in this dataset, Lisbon ranks 73 for seismic hazard, the 54th percentile within the state. About 11,127 people live in Lisbon, Wisconsin.

What a retrofit costs in Lisbon

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 Lisbon address.
