Where Nebraska City sits in Nebraska

USGS's underlying values for Nebraska City: 0.038g peak ground acceleration, 0.079g at short period, 0.049g at 1 second. Within Nebraska alone, Nebraska City ranks 10 of 32 cities by seismic hazard - the 71th percentile in-state. Nebraska City has a population of about 7,526.

Bracing and bolting: the actual cost

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.
