Poplar Bluff, MO: what USGS's seismic model says

Poplar Bluff carries Seismic Design Category D under USGS's ASCE 7-16 model. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Poplar Bluff sits at the 93th percentile for seismic hazard among 4,875 US cities.

Poplar Bluff by the numbers

USGS's underlying values for Poplar Bluff: 0.616g peak ground acceleration, 1.014g at short period, 0.336g at 1 second. Within Missouri alone, Poplar Bluff ranks 6 of 135 cities by seismic hazard - the 96th percentile in-state. Poplar Bluff has a population of about 16,177.

Retrofit economics for Poplar Bluff

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.

Insuring against this, not just retrofitting

A Poplar Bluff 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.
