Tarboro, NC: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Tarboro is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Tarboro sits at the 27th percentile for seismic hazard among 4,875 US cities.

Tarboro by the numbers

USGS's underlying values for Tarboro: 0.046g peak ground acceleration, 0.098g at short period, 0.048g at 1 second. Within North Carolina alone, Tarboro ranks 141 of 147 cities by seismic hazard - the 4th percentile in-state. Tarboro has a population of about 10,954.

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 North Carolina 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 North Carolina.

What this means for insurance

A Tarboro 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 Tarboro's figures come from

Tarboro'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 Tarboro.
