Murphy, TX: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Murphy is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Murphy ranks above 32% of the 4,875 cities in this dataset for seismic hazard - the 32th percentile.

How Murphy compares

The raw figures: peak ground acceleration 0.053g, short-period spectral response 0.11g, 1-second spectral response 0.057g. Among 384 Texas cities in this dataset, Murphy ranks 71 for seismic hazard, the 82th percentile within the state. About 21,109 people live in Murphy, Texas.

Retrofit economics for Murphy

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 Murphy 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 Murphy address.
