Diboll, TX: what USGS's seismic model says

Diboll 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. Rank it against the rest of the country and Diboll sits at the 21th percentile for seismic hazard among 4,875 US cities.

Diboll by the numbers

USGS's underlying values for Diboll: 0.041g peak ground acceleration, 0.085g at short period, 0.051g at 1 second. Within Texas alone, Diboll ranks 160 of 384 cities by seismic hazard - the 58th percentile in-state. Diboll has a population of about 5,108.

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 Texas 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 Texas.

Insuring against this, not just retrofitting

A Diboll 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 Diboll's figures come from

Diboll'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 Diboll.
