Trumann, AR: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Trumann in Seismic Design Category D: 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. Nationally, Trumann ranks above 98% of the 4,875 cities in this dataset for seismic hazard - the 98th percentile.

Where Trumann sits in Arkansas

USGS's underlying values for Trumann: 1.235g peak ground acceleration, 1.904g at short period, 0.662g at 1 second. Within Arkansas alone, Trumann ranks 3 of 68 cities by seismic hazard - the 97th percentile in-state. Trumann has a population of about 7,425.

What a retrofit costs in Trumann

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 Arkansas 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 Arkansas.

Insuring against this, not just retrofitting

A Trumann 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 Trumann's figures come from

Trumann's Category D 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 D does and doesn't tell you about Trumann.
