Eufaula's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Eufaula 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 Eufaula sits at the 27th percentile for seismic hazard among 4,875 US cities.

How Eufaula compares

USGS's underlying values for Eufaula: 0.046g peak ground acceleration, 0.099g at short period, 0.064g at 1 second. Within Alabama alone, Eufaula ranks 91 of 107 cities by seismic hazard - the 15th percentile in-state. Eufaula has a population of about 12,363.

What a retrofit costs in Eufaula

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 Alabama 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 Alabama.

Insuring against this, not just retrofitting

A Eufaula 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 Eufaula's figures come from

Eufaula'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 Eufaula.
