Moore, OK: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Moore in Seismic Design 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 Moore sits at the 77th percentile for seismic hazard among 4,875 US cities.

Where Moore sits in Oklahoma

USGS's underlying values for Moore: 0.201g peak ground acceleration, 0.329g at short period, 0.084g at 1 second. Within Oklahoma alone, Moore ranks 13 of 75 cities by seismic hazard - the 84th percentile in-state. Moore has a population of about 63,845.

Retrofit economics for Moore

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.

Earthquake insurance for a Moore home

A Moore 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 Moore's figures come from

Moore'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 Moore.
