Cairo, GA: what USGS's seismic model says
Under the seismic model IBC and ASCE 7 use for new construction, Cairo is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Cairo ranks above 20% of the 4,875 cities in this dataset for seismic hazard - the 20th percentile.
Where Cairo sits in Georgia
USGS's underlying values for Cairo: 0.038g peak ground acceleration, 0.081g at short period, 0.054g at 1 second. Within Georgia alone, Cairo ranks 147 of 148 cities by seismic hazard - the 1th percentile in-state. Cairo has a population of about 10,057.
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 Georgia 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 Georgia.
Earthquake insurance for a Cairo home
A Cairo 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 Cairo's figures come from
Cairo'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 Cairo.
