Smithfield, VA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Smithfield in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Smithfield sits at the 15th percentile for seismic hazard among 4,875 US cities.

How Smithfield compares

USGS's underlying values for Smithfield: 0.049g peak ground acceleration, 0.1g at short period, 0.042g at 1 second. Within Virginia alone, Smithfield ranks 56 of 63 cities by seismic hazard - the 11th percentile in-state. Smithfield has a population of about 9,032.

What a retrofit costs in Smithfield

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 Smithfield home

A Smithfield 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.

Smithfield's Category A 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 A does and doesn't tell you about Smithfield.
