Zanesville's Seismic Design Category, explained

Zanesville 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 Zanesville sits at the 31th percentile for seismic hazard among 4,875 US cities.

How Zanesville compares

USGS's underlying values for Zanesville: 0.051g peak ground acceleration, 0.104g at short period, 0.054g at 1 second. Within Ohio alone, Zanesville ranks 244 of 254 cities by seismic hazard - the 4th percentile in-state. Zanesville has a population of about 24,916.

What a retrofit costs in Zanesville

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 Zanesville 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 Zanesville's figures come from

Zanesville'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 Zanesville.
