Alamogordo's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Alamogordo 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. Rank it against the rest of the country and Alamogordo sits at the 73th percentile for seismic hazard among 4,875 US cities.

Alamogordo by the numbers

USGS's underlying values for Alamogordo: 0.132g peak ground acceleration, 0.318g at short period, 0.104g at 1 second. Within New Mexico alone, Alamogordo ranks 15 of 35 cities by seismic hazard - the 59th percentile in-state. Alamogordo has a population of about 31,667.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by New Mexico specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in New Mexico.

Earthquake insurance for a Alamogordo home

A Alamogordo homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Alamogordo's figures come from

Alamogordo's Category C and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category C does and doesn't tell you about Alamogordo.
