Noble, OK: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Noble is Category C. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Noble sits at the 78th percentile for seismic hazard among 4,875 US cities.

Where Noble sits in Oklahoma

USGS's underlying values for Noble: 0.212g peak ground acceleration, 0.345g at short period, 0.086g at 1 second. Within Oklahoma alone, Noble ranks 11 of 75 cities by seismic hazard - the 86th percentile in-state. Noble has a population of about 7,779.

What a retrofit costs in Noble

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 Oklahoma 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 Oklahoma.

What this means for insurance

A Noble 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.

Where Noble's figures come from

Noble's Category C and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category C does and doesn't tell you about Noble.
