Martins Ferry's Seismic Design Category, explained
Martins Ferry carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Martins Ferry sits at the 24th percentile for seismic hazard among 4,875 US cities.
How Martins Ferry compares
USGS's underlying values for Martins Ferry: 0.044g peak ground acceleration, 0.092g at short period, 0.048g at 1 second. Within Ohio alone, Martins Ferry ranks 254 of 254 cities by seismic hazard - the 0th percentile in-state. Martins Ferry has a population of about 6,050.
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 Ohio 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 Ohio.
What this means for insurance
A Martins Ferry 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 Martins Ferry's figures come from
Martins Ferry'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 Martins Ferry.
