Xenia, OH: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Xenia is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Xenia in the 45th percentile nationally for seismic hazard - higher than 45% of the 4,875 US cities USGS was checked against here.

How Xenia compares

USGS's underlying values for Xenia: 0.07g peak ground acceleration, 0.137g at short period, 0.069g at 1 second. Within Ohio alone, Xenia ranks 122 of 254 cities by seismic hazard - the 52th percentile in-state. Xenia has a population of about 26,067.

Retrofit economics for Xenia

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 Xenia 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 Xenia's figures come from

Xenia'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 Xenia.
