Galax's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Galax in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Galax in the 60th percentile nationally for seismic hazard - higher than 60% of the 4,875 US cities USGS was checked against here.

Galax by the numbers

USGS's underlying values for Galax: 0.136g peak ground acceleration, 0.237g at short period, 0.075g at 1 second. Within Virginia alone, Galax ranks 12 of 63 cities by seismic hazard - the 82th percentile in-state. Galax has a population of about 6,739.

Retrofit economics for Galax

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 Virginia 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 Virginia.

What this means for insurance

A Galax 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 Galax's figures come from

Galax'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 Galax.
