Palatka, FL: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Palatka in Seismic Design 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 Palatka sits at the 20th percentile for seismic hazard among 4,875 US cities.

Where Palatka sits in Florida

USGS's underlying values for Palatka: 0.039g peak ground acceleration, 0.081g at short period, 0.043g at 1 second. Within Florida alone, Palatka ranks 15 of 228 cities by seismic hazard - the 94th percentile in-state. Palatka has a population of about 10,867.

Retrofit economics for Palatka

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 Florida 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 Florida.

Insuring against this, not just retrofitting

A Palatka 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 Palatka's figures come from

Palatka'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 Palatka.
