Monahans, TX: what USGS's seismic model says
USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Monahans in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Monahans in the 55th percentile nationally for seismic hazard - higher than 55% of the 4,875 US cities USGS was checked against here.
Monahans by the numbers
The raw figures: peak ground acceleration 0.096g, short-period spectral response 0.173g, 1-second spectral response 0.043g. Among 384 Texas cities in this dataset, Monahans ranks 11 for seismic hazard, the 97th percentile within the state. About 7,334 people live in Monahans, Texas.
Retrofit economics for Monahans
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.
Earthquake insurance for a Monahans home
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 Monahans address.
