Does Truth or Consequences, NM need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Truth or Consequences in Seismic Design Category C: 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. That puts Truth or Consequences in the 73th percentile nationally for seismic hazard - higher than 73% of the 4,875 US cities USGS was checked against here.

Truth or Consequences by the numbers

The raw figures: peak ground acceleration 0.133g, short-period spectral response 0.3g, 1-second spectral response 0.097g. Among 35 New Mexico cities in this dataset, Truth or Consequences ranks 14 for seismic hazard, the 62th percentile within the state. About 5,942 people live in Truth or Consequences, New Mexico.

What a retrofit costs in Truth or Consequences

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 Truth or Consequences 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 Truth or Consequences address.
