Bloomsburg, PA: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Bloomsburg is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Bloomsburg in the 34th percentile nationally for seismic hazard - higher than 34% of the 4,875 US cities USGS was checked against here.

Where Bloomsburg sits in Pennsylvania

The raw figures: peak ground acceleration 0.056g, short-period spectral response 0.114g, 1-second spectral response 0.042g. Among 193 Pennsylvania cities in this dataset, Bloomsburg ranks 109 for seismic hazard, the 44th percentile within the state. About 13,286 people live in Bloomsburg, Pennsylvania.

Retrofit economics for Bloomsburg

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Pennsylvania. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Bloomsburg home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Bloomsburg address.
