What stands out about Atka’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
Does Atka flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Atka. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
How exposed is Atka?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 100% of U.S. communities, mostly from tsunamis.
Rated higher than 351 of the 352 Alaska towns we cover.
Atka is smaller than a census tract, so it shares the figures of the tract around its center.

Get ready for what Atka actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Strong shaking or a sudden drop in the sea means head for high ground now.
- Learn the tsunami route signs near the shore.
- Stay away until officials say it’s safe.
- Drop, cover and hold on.
- Strap tall furniture and the water heater to the wall.
- Know how to shut off the gas.
- Keep a shovel, a blanket and snacks in the car.
- Clear snow from furnace and dryer vents.
- Check on older neighbors when the power goes out.
- Look up the address on FEMA’s flood map.
- Ask the seller or landlord whether it has ever flooded, and what flood insurance costs there.
- Get a flood insurance quote early: policies usually start 30 days after you buy.

What these numbers can and can’t tell you
- An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
- Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
- Money that reached town. Flood claims are matched to Atka’s own flood-insurance community; household aid to the registrant’s city; repair grants to the City of Atka.
- It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
