Most disasters give some warning. An earthquake gives none. One moment everything is normal, and the next the ground itself, the one thing we all unconsciously trust to hold still, is trying to throw you off your feet. That total lack of warning means earthquake preparedness is almost entirely about two things done in advance: preparing your home so it does not hurt you, and training the reflex you will need in the few seconds you have to react.
The reflex: Drop, Cover, and Hold On
When the shaking starts, you have no time to think, so you need a trained response. The official, evidence-based reaction used by emergency management agencies and earthquake researchers alike is Drop, Cover, and Hold On:
- Drop to your hands and knees before the quake knocks you down. This protects you and lets you crawl to shelter.
- Cover your head and neck, and if possible get under a sturdy table or desk. If no shelter is near, get against an interior wall away from windows and cover your head with your arms.
- Hold On to your shelter and be ready to move with it until the shaking stops.
Forget the “triangle of life”
You may have seen a viral message claiming you should lie beside furniture rather than under it, the so-called triangle of life. Emergency and rescue professionals have thoroughly debunked it, and following it can get you killed. In the parts of the world with the most earthquake experience, the guidance is unambiguous: Drop, Cover, and Hold On. Do not run outside during shaking either, since most injuries happen from falling debris while people try to move. Stay put, get low, and cover.
Make your home stop hurting you
In an earthquake, your own house becomes the threat. The injuries come from falling objects, breaking glass, and toppling furniture, and nearly all of it is preventable with an afternoon of work.
| Hazard | Fix |
|---|---|
| Tall furniture (bookcases, dressers) | Anchor to wall studs with straps or brackets |
| Water heater | Strap to the wall; a toppled heater can rupture gas and water lines |
| Heavy or breakable items on high shelves | Move down low, away from beds and seating |
| TVs and electronics | Secure with mounting straps or furniture anchors |
| Cabinet doors | Add child-safety-style latches so contents do not fly open |
- Anchor tall furniture to wall studs: bookcases, dressers, cabinets, and especially the water heater, which can rupture gas and water lines when it topples.
- Move heavy items down low. Keep the heavy and breakable things off high shelves and away from beds and seating.
- Secure the television and electronics, and use latches on cabinets so they do not fly open.
- Keep sturdy shoes and a light next to every bed, because a nighttime quake leaves broken glass across every floor and you must be able to move safely in the dark.

Where you are matters: adapting the reflex
Drop, Cover, and Hold On is universal, but where you happen to be when the shaking starts changes the details. In bed, stay there and cover your head with a pillow rather than trying to run to a doorway or table, since most injuries during a quake happen from people moving through a dark, debris-filled room. In a vehicle, pull over away from bridges, overpasses, and power lines, and stay inside with your seatbelt on until the shaking stops. Outdoors, move to an open area away from buildings, trees, and power lines if you can do so safely, and drop and cover where you stand if you cannot. In a crowded public place, avoid the rush toward exits, since crowd crush during the shaking itself is a real and often underestimated risk.
After the shaking: gas, water, and aftershocks
When the initial quake stops, the emergency is not over. Expect aftershocks, some nearly as strong as the main event, and be ready to Drop, Cover, and Hold On again. Then work through the aftermath:
- Check for gas leaks. If you smell gas or hear hissing, shut off the main gas valve, leave, and do not use any flame or electrical switch, including light switches, which can spark. Learn where your shutoff is and keep a wrench beside it now.
- Check for injuries and hazards: people first, then downed lines, broken glass, and structural damage.
- Assume water is unsafe until officials confirm otherwise, and rely on stored or filtered water.
- Expect a long outage. Earthquakes can knock out power and water across a whole region, so your home kit and grid-down plan matter here as much as in any disaster.
Common questions
How long do aftershocks typically continue?
Noticeable aftershocks commonly continue for days to weeks after a significant quake, and occasionally longer after very large events, generally decreasing in frequency and strength over time. Keep your household on the Drop, Cover, and Hold On reflex until local seismologists or emergency officials indicate the aftershock sequence has meaningfully quieted.
Should I turn off my gas as a precaution even if I do not smell a leak?
Not automatically. Utilities generally advise against shutting off gas unless you smell it, hear it, or see visible damage to gas lines or appliances, because a shutoff valve, once closed, often requires a professional to safely restore and re-light the system, which can leave a household without gas for an extended period during an already stressful time.
Is there any real warning before an earthquake at all?
Some regions now have early warning systems, such as ShakeAlert on the U.S. West Coast, that can provide anywhere from a few seconds to just over a minute of warning by detecting a quake’s initial waves before the stronger shaking arrives. It is not advance notice in the way a hurricane forecast is, but a few seconds is genuinely enough time to drop and cover if your phone or a connected device alerts you, which is worth enabling if you live in a covered region.
Earthquake readiness, condensed
- No warning means the reflex is everything: Drop, Cover, and Hold On.
- Ignore the “triangle of life” myth and do not run outside during shaking.
- Anchor furniture and the water heater; keep shoes and a light by every bed.
- Adapt the reflex to where you are: bed, car, outdoors, or a crowd.
- After: check for gas leaks, expect aftershocks, treat water as unsafe.
You cannot predict the earthquake, but you can make your home a place that shelters you instead of injuring you, and you can train the one reflex that protects you in the seconds that count. Spend the afternoon anchoring furniture and practicing Drop, Cover, and Hold On with your family. When the ground moves, that preparation is the only thing you will have time to rely on.
