Green, OH: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Green is Category B. 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 Green sits at the 36th percentile for seismic hazard among 4,875 US cities.

Where Green sits in Ohio

USGS's underlying values for Green: 0.059g peak ground acceleration, 0.115g at short period, 0.049g at 1 second. Within Ohio alone, Green ranks 202 of 254 cities by seismic hazard - the 21th percentile in-state. Green has a population of about 27,476.

Retrofit economics for Green

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.

Earthquake insurance for a Green home

A Green 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 Green's figures come from

Green'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 Green.
