Does Kingston, PA need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Kingston in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Kingston in the 38th percentile nationally for seismic hazard - higher than 38% of the 4,875 US cities USGS was checked against here.

Where Kingston sits in Pennsylvania

USGS's underlying values for Kingston: 0.061g peak ground acceleration, 0.123g at short period, 0.044g at 1 second. Within Pennsylvania alone, Kingston ranks 98 of 193 cities by seismic hazard - the 49th percentile in-state. Kingston has a population of about 13,476.

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 Pennsylvania 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 Pennsylvania.

Insuring against this, not just retrofitting

A Kingston 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 Kingston's figures come from

Kingston'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 Kingston.
