Somers, WI: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Somers in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Somers in the 24th percentile nationally for seismic hazard - higher than 24% of the 4,875 US cities USGS was checked against here.

How Somers compares

The raw figures: peak ground acceleration 0.043g, short-period spectral response 0.087g, 1-second spectral response 0.052g. Among 157 Wisconsin cities in this dataset, Somers ranks 12 for seismic hazard, the 93th percentile within the state. About 8,194 people live in Somers, Wisconsin.

Bracing and bolting: the actual cost

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 Somers address.
