How to earthquake-proof your home
Most earthquake injuries come from falling objects, not collapsing buildings. What to anchor, in what order, and what each measure costs.
When people picture earthquake damage they picture split buildings. But in most quakes a person experiences in a lifetime, the building holds and the harm comes from what was inside it: a bookcase tipping over, a television launching off its stand, dishes pouring out of a cabinet that opened on its own.
Start with what can fall on you while you sleep
The test is not what an object is worth but where it sits and what it weighs. Walk through the house looking up and ask one question in each room: if this comes loose, who is underneath?
Heavy pictures and mirrors above the head of a bed are the clearest case and the easiest to fix: move them to another wall, or hang them on closed hooks instead of an open nail.
The four anchors that change the outcome most
| Item | Risk if unanchored | Fix |
|---|---|---|
| Tall shelving or bookcase | Tips onto a person or blocks the exit | Metal bracket into a stud |
| Television | Launches off the stand | Safety strap to the mount |
| Water heater | Breaks gas and water when it falls | Two-band metal kit |
| Kitchen cabinets | Swing open and empty dishes | Latch closures |
The water heater deserves its own paragraph
It is the single item that shows up most often in post-earthquake reports. When it topples it tears out the gas connection and the water line in the same motion, producing a fire risk and a flood at once.
A water heater still standing is also 30 to 50 gallons of drinkable water at exactly the moment the mains may be down. Strapping it is not only prevention: it is storage.
Small things count too
- Museum putty under vases, figurines and shelf objects. It costs almost nothing and keeps them from becoming projectiles.
- Latches on kitchen cabinets. Dishes on the floor are what turns your own kitchen into a room you cannot walk through barefoot.
- Nothing heavy over beds or sofas. The simplest rule and the most ignored.
- Locked casters on furniture with wheels, or it rolls on its own.
What to check once a year
Anchors loosen, furniture gets moved and rooms get rearranged. A fifteen-minute annual check is enough:
- Tug gently on each anchored item to confirm it still holds.
- Look for anything new and heavy hung above a bed or sofa.
- Confirm the gas shutoff is still accessible and the wrench is tied beside the meter.
- Check that the flashlight by the bed still has charge.
- What to do after an earthquake: the first 24 hours Aftershocks, gas leaks, water that is no longer safe and a house that may not be. The order to check things in once the shaking stops.
- What to do during an earthquake: the first 60 seconds Drop, cover and hold on. Exactly what to do depending on where the shaking catches you, and why running for the door is the worst move.
- 3-day vs 7-day kit: what actually changes Going from three days to seven is not doubling everything. Water scales linearly, food does not, and power depends on what you decide to keep running.

Furniture strap and bracket kit
Covers shelving, bookcases and dressers. Choose ones that fasten into wall studs, not just drywall, or the anchor gives way with the furniture.

Water heater strapping kit
Purpose-built kits include two metal bands and spacers. It is the one part that prevents a gas leak and a water leak at once.

Cabinet safety latches
They keep doors from swinging open during shaking and emptying dishes onto the floor, exactly where you will have to walk afterwards.
Frequently asked questions
What should I anchor first in my house?
Whatever is tall, heavy and near where someone sleeps or sits. In that order: tall shelving and bookcases, the television, the water heater, and framed pictures or mirrors above beds and sofas.
Does anchoring furniture help in a large earthquake?
Yes. In moderate and large quakes a substantial share of injuries come from objects falling or sliding, not from structural collapse. Anchoring reduces that risk regardless of magnitude.
Why does the water heater need strapping?
Because when it topples it breaks the gas connection and the water line at the same time: a fire risk and a leak in one motion. A water heater left standing is also 30 to 50 gallons of drinkable water.
What does earthquake-proofing a house cost?
The highest-impact measures are low cost: furniture straps, metal brackets, cabinet latches and museum putty. Structural retrofitting is a separate category and needs a professional.
