Las Cruces's Seismic Design Category, explained

Las Cruces carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Las Cruces sits at the 72th percentile for seismic hazard among 4,875 US cities.

Las Cruces by the numbers

The raw figures: peak ground acceleration 0.123g, short-period spectral response 0.275g, 1-second spectral response 0.091g. Among 35 New Mexico cities in this dataset, Las Cruces ranks 18 for seismic hazard, the 50th percentile within the state. About 116,998 people live in Las Cruces, New Mexico.

Retrofit economics for Las Cruces

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

Earthquake insurance for a Las Cruces 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 Las Cruces address.
