Idabel's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Idabel in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Idabel ranks above 40% of the 4,875 cities in this dataset for seismic hazard - the 40th percentile.

Where Idabel sits in Oklahoma

The raw figures: peak ground acceleration 0.064g, short-period spectral response 0.133g, 1-second spectral response 0.075g. Among 75 Oklahoma cities in this dataset, Idabel ranks 62 for seismic hazard, the 18th percentile within the state. About 6,983 people live in Idabel, Oklahoma.

What a retrofit costs in Idabel

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 Idabel 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 Idabel address.

More on how this number was built

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