Earthquakes risk in Georgia

Where Georgia's earthquakes actually come from

If you live in Savannah, Augusta, or anywhere along the South Carolina border, you're closer to a real seismic zone than you might think. The ground under Georgia is mostly quiet, but it's not dead. The two main sources of shaking are the South Carolina seismic zone, which includes the Charleston area, and the Eastern Tennessee seismic zone that stretches down into the northwest corner of Georgia — counties like Dade, Walker, and Catoosa. There's also the occasional deep quake that rumbles far away but still gets felt in the Atlanta metro.

Georgia's statewide earthquake rating is 2 out of 5. That means low risk, not no risk. The 1886 Charleston earthquake was strong enough to crack buildings in Savannah and Augusta. We're not talking about California-style destruction, but a magnitude 5 or 6 near the border could knock chimneys down and shake loose old brick.

What actually happens to a house

Most Georgia homes are wood-frame, which is good news. Wood flexes. It creaks and groans, but it rarely collapses in the kind of shaking we get here. The damage you're more likely to see is cosmetic but expensive: cracked drywall, separated brick veneer, a chimney that shifts, or a water heater that tips over and starts a gas leak. That last one causes more house fires after earthquakes than the shaking itself.

Older homes — especially those with unreinforced brick foundations or tall brick chimneys — are the most vulnerable. If you own a century-old house in Macon or Columbus, a moderate quake could mean a rebuild of that chimney. Newer homes with properly braced walls usually ride it out. Mobile homes and manufactured housing can slide off their piers if they're not tied down.

If you only do three things

I'd spend a free weekend and about $100 on these before I even looked at an earthquake policy. First, strap your water heater to the wall studs with metal plumber's tape. Second, anchor tall bookcases, TVs, and dressers to the walls. Third, learn where your gas shut-off valve is and keep a wrench near it. That's it. Those three steps cost almost nothing and prevent the most common earthquake-related damage and injuries in Georgia homes.

If you have more time, walk your foundation and look for existing cracks. Fix them now so you can tell what's new after a quake. And if you live in a brick home, talk to a contractor about reinforcing the chimney — that's the piece most likely to come down.

Questions we get

Does Georgia really have earthquakes?

Yes, but they're usually small — magnitude 2 or 3, and you won't feel them. Every few years, though, a slightly larger one gets felt. The risk is highest near the South Carolina border and in the northwest mountains. The Georgia Emergency Management and Homeland Security Agency tracks these events and posts updates.

Will my homeowners insurance cover earthquake damage in Georgia?

Almost never. Standard homeowners policies in Georgia exclude earthquake damage. You have to buy a separate endorsement or a stand-alone policy. Because the risk is low, many insurers offer it as an add-on, but the deductible is typically 10% to 15% of your home's insured value. On a $300,000 house, that's $30,000 to $45,000 out of pocket before the policy pays a dime. That's why many Georgia homeowners skip it — and that's a reasonable choice if you've done the cheap retrofits first.

What's the difference between earthquake and flood insurance for a Georgia home?

They're completely separate. Flood insurance comes through the National Flood Insurance Program or a private carrier. Earthquake insurance is a separate endorsement or policy. Neither is included in a standard homeowners policy. If you live near the coast, you might already have flood coverage, but that won't help with shaking. And if you buy earthquake coverage, it won't help with storm surge. You need to read your policy declarations page to see what's actually covered.
