Danville, VA: what USGS's seismic model says

Danville carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Danville in the 44th percentile nationally for seismic hazard - higher than 44% of the 4,875 US cities USGS was checked against here.

Danville by the numbers

USGS's underlying values for Danville: 0.068g peak ground acceleration, 0.137g at short period, 0.06g at 1 second. Within Virginia alone, Danville ranks 46 of 63 cities by seismic hazard - the 27th percentile in-state. Danville has a population of about 41,993.

Retrofit economics for Danville

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.

Earthquake insurance for a Danville home

A Danville 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 Danville's figures come from

Danville'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 Danville.
