Cushing's Seismic Design Category, explained

Cushing 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. Nationally, Cushing ranks above 51% of the 4,875 cities in this dataset for seismic hazard - the 51th percentile.

Where Cushing sits in Oklahoma

The raw figures: peak ground acceleration 0.081g, short-period spectral response 0.158g, 1-second spectral response 0.07g. Among 75 Oklahoma cities in this dataset, Cushing ranks 44 for seismic hazard, the 42th percentile within the state. About 8,444 people live in Cushing, Oklahoma.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Cushing 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 Cushing address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Cushing'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.
