Bloomfield's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Bloomfield is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Bloomfield ranks above 52% of the 4,875 cities in this dataset for seismic hazard - the 52th percentile.

Where Bloomfield sits in New Mexico

USGS's underlying values for Bloomfield: 0.086g peak ground acceleration, 0.174g at short period, 0.059g at 1 second. Within New Mexico alone, Bloomfield ranks 25 of 35 cities by seismic hazard - the 29th percentile in-state. Bloomfield has a population of about 7,363.

Retrofit economics for Bloomfield

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.

Insuring against this, not just retrofitting

A Bloomfield 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 Bloomfield's figures come from

Bloomfield's Category B 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 B does and doesn't tell you about Bloomfield.
