Wyoming's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Wyoming in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Wyoming ranks above 23% of the 4,875 cities in this dataset for seismic hazard - the 23th percentile.

Where Wyoming sits in Michigan

USGS's underlying values for Wyoming: 0.042g peak ground acceleration, 0.087g at short period, 0.047g at 1 second. Within Michigan alone, Wyoming ranks 102 of 153 cities by seismic hazard - the 34th percentile in-state. Wyoming has a population of about 78,559.

Retrofit economics for Wyoming

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Michigan specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Michigan.

Earthquake insurance for a Wyoming home

A Wyoming homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Wyoming's figures come from

Wyoming's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Wyoming.
