Brandon, MS: what USGS's seismic model says
USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Brandon in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Brandon ranks above 43% of the 4,875 cities in this dataset for seismic hazard - the 43th percentile.
How Brandon compares
USGS's underlying values for Brandon: 0.067g peak ground acceleration, 0.139g at short period, 0.082g at 1 second. Within Mississippi alone, Brandon ranks 37 of 61 cities by seismic hazard - the 40th percentile in-state. Brandon has a population of about 25,870.
Bracing and bolting: the actual cost
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 Mississippi 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 Mississippi.
Earthquake insurance for a Brandon home
A Brandon 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 Brandon's figures come from
Brandon'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 Brandon.
