Shamokin's Seismic Design Category, explained

Shamokin carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Shamokin in the 37th percentile nationally for seismic hazard - higher than 37% of the 4,875 US cities USGS was checked against here.

Where Shamokin sits in Pennsylvania

The raw figures: peak ground acceleration 0.06g, short-period spectral response 0.119g, 1-second spectral response 0.042g. Among 193 Pennsylvania cities in this dataset, Shamokin ranks 103 for seismic hazard, the 47th percentile within the state. About 6,787 people live in Shamokin, Pennsylvania.

What a retrofit costs in Shamokin

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 Shamokin 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 Shamokin address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Shamokin's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
