Corry, PA: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Corry is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Corry sits at the 15th percentile for seismic hazard among 4,875 US cities.

Corry by the numbers

USGS's underlying values for Corry: 0.05g peak ground acceleration, 0.101g at short period, 0.039g at 1 second. Within Pennsylvania alone, Corry ranks 174 of 193 cities by seismic hazard - the 10th percentile in-state. Corry has a population of about 6,065.

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.

Earthquake insurance for a Corry home

A Corry 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.
