White Oak, PA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places White Oak 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 White Oak sits at the 22th percentile for seismic hazard among 4,875 US cities.

Where White Oak sits in Pennsylvania

USGS's underlying values for White Oak: 0.042g peak ground acceleration, 0.088g at short period, 0.045g at 1 second. Within Pennsylvania alone, White Oak ranks 156 of 193 cities by seismic hazard - the 19th percentile in-state. White Oak has a population of about 7,352.

Retrofit economics for White Oak

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 White Oak 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.
