Where Stonecrest sits in Georgia

USGS's underlying values for Stonecrest: 0.087g peak ground acceleration, 0.175g at short period, 0.083g at 1 second. Within Georgia alone, Stonecrest ranks 99 of 148 cities by seismic hazard - the 33th percentile in-state. Stonecrest has a population of about 61,015.

What a retrofit costs in Stonecrest

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 Georgia 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 Georgia.

Insuring against this, not just retrofitting

A Stonecrest 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.
