Macon's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Macon in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Macon in the 33th percentile nationally for seismic hazard - higher than 33% of the 4,875 US cities USGS was checked against here.

Where Macon sits in Missouri

USGS's underlying values for Macon: 0.055g peak ground acceleration, 0.116g at short period, 0.076g at 1 second. Within Missouri alone, Macon ranks 104 of 135 cities by seismic hazard - the 23th percentile in-state. Macon has a population of about 5,509.

Retrofit economics for Macon

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 Missouri 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 Missouri.

Earthquake insurance for a Macon home

A Macon 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 Macon's figures come from

Macon'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 Macon.
