Kilgore, TX: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Kilgore is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Kilgore in the 29th percentile nationally for seismic hazard - higher than 29% of the 4,875 US cities USGS was checked against here.

Where Kilgore sits in Texas

The raw figures: peak ground acceleration 0.048g, short-period spectral response 0.099g, 1-second spectral response 0.062g. Among 384 Texas cities in this dataset, Kilgore ranks 98 for seismic hazard, the 75th percentile within the state. About 13,583 people live in Kilgore, Texas.

Retrofit economics for Kilgore

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Texas. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

What this means for insurance

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Kilgore address.
