Kearney by the numbers

USGS's underlying values for Kearney: 0.038g peak ground acceleration, 0.08g at short period, 0.039g at 1 second. Within Nebraska alone, Kearney ranks 29 of 32 cities by seismic hazard - the 10th percentile in-state. Kearney has a population of about 34,741.

What a retrofit costs in Kearney

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 Nebraska 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 Nebraska.

Insuring against this, not just retrofitting

A Kearney 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.
