Is Your Home Ready to Survive an Earthquake?

Walk through any home in a seismically active region and you’ll almost always find the same thing: a tall bookshelf loaded with books, standing against a wall, not anchored to anything. Maybe a flat-screen TV balanced on a low dresser. A water heater that’s never been strapped. People have thought about earthquake preparedness — they’ve got bottled water, maybe a flashlight — but they’ve never looked at their own living room as a projectile field. That gap between “I’m aware of earthquakes” and “I’ve actually looked at what will fall on me” is where most of the real harm comes from. Not from the building coming down. From what’s already inside it.

The Room-by-Room Walk: What to Look For Before the Ground Moves

Start with the tallest objects in each room. Bookshelves, wardrobes, refrigerators, filing cabinets — anything taller than about four feet that isn’t connected to the wall is a hazard. During strong shaking, these don’t just tip slowly. They snap forward faster than most people expect, and they do it in the dark if the shaking happens at night. The bedroom is usually the most dangerous room in the house, because that’s where people are horizontal and least able to react.

In the kitchen, open every cabinet and think about what will come out. Heavy ceramic dishes stacked on high shelves will come down. Glass jars on exposed shelving will shatter. The cabinet above the refrigerator — often used for rarely-needed items — tends to be overloaded with heavy things that nobody thinks about until they’re on the floor. Latching cabinet hardware is inexpensive and widely available at hardware stores; a set of adhesive cabinet latches can be installed in an afternoon and will keep most kitchen contents in place through moderate shaking.

In the living room, check whether your television is secured to the wall or furniture. A flat-screen TV falling from a media console is a common source of injury — and it’s one of the easiest hazards to fix with a basic TV strap kit, which runs under twenty dollars at most hardware retailers. Look also at any decorative items on high shelves: picture frames, vases, items on mantelpieces. These become projectiles.

Use the FEMA earthquake safety resources as your baseline guide — it’s organized by room and covers items that are easy to overlook. Walk through it physically, not mentally. There’s a meaningful difference.

Furniture Anchoring: The One Action That Prevents More Injuries Than Anything Else

A pattern seen repeatedly in post-earthquake damage surveys is this: the majority of indoor injuries come from what falls on people, not from structural failure. Buildings in earthquake-prone regions of North America are generally built to survive strong shaking. Furniture is not. Securing furniture beforehand prevents more harm than almost any action you could take during the shaking itself.

Anchoring doesn’t require a contractor or special skills. The basic approach is an L-bracket or furniture strap screwed into a wall stud on one end and into the back of the furniture piece on the other. The critical part is finding a stud — attaching hardware to drywall alone won’t hold under lateral force. A stud finder (available at hardware stores for around fifteen dollars) makes this straightforward. If you’re renting and can’t put holes in walls, look for furniture straps with adhesive mounting plates rated for earthquake loads; these exist specifically for rental situations and will handle most realistic shaking scenarios.

Priority order for anchoring, if you’re doing it in stages:

• Tall furniture in bedrooms first — this is where people are most vulnerable and least mobile
• Water heaters — unstrapped water heaters are a leading cause of gas line damage and post-quake fires
• Refrigerators — heavy, mobile, and positioned near hard flooring
• Bookshelves and wardrobes in common areas
• TV and electronics on elevated surfaces

Even anchoring two or three pieces in the bedroom and kitchen puts you significantly ahead of most households. Don’t let perfect be the enemy of done here.

Your Gas Shutoff: Know Where It Is Before You Need It

Post-earthquake fires are often traced back to one thing: gas lines damaged by shaking or by falling objects that hit pipes, and nobody shutting the gas off because they didn’t know how or where the shutoff valve was located. In many homes, the gas meter and shutoff valve are outside, near the foundation — but their exact position varies by utility and home layout.

Find your gas shutoff valve today, not after the shaking stops. It’s typically located on the gas meter itself, and shutting it off requires a wrench — the valve turns 90 degrees perpendicular to the pipe to close. Some households keep a dedicated crescent wrench zip-tied near the meter specifically for this purpose. If you smell gas after an earthquake, don’t try to diagnose the source. Get out, leave doors open as you go, and call your utility company from a distance.

Automatic gas shutoff valves (also called seismic shutoff valves) install on your main gas line and trigger automatically when they detect earthquake-level shaking. They’re a worthwhile investment for households in high-risk areas, and in some states they’re required by building code for new construction. Your local gas utility can usually recommend licensed installers.

Know also where your home’s main electrical panel is and how to switch off individual circuits — electrical fires after earthquakes are common when wiring is damaged and power is restored before damage is assessed. The water main shutoff matters too, particularly if pipes are visible and could be damaged.

Structural Cracks: How to Tell the Difference Between Cosmetic and Concerning

Not every crack in a wall is serious. Hairline cracks in drywall or plaster near door frames and window corners are extremely common — they reflect normal settling and seasonal expansion. The cracks that warrant professional evaluation are different in character. Look for:

• Diagonal stair-step cracks in brick or concrete block walls — these suggest differential settlement or shear movement
• Cracks that are wider than a quarter-inch, or that are wider at one end than the other
• Horizontal cracks in foundation walls — these can indicate soil pressure or structural movement
• Cracks that pass all the way through a wall to the other side
• Any crack that has appeared or grown noticeably since a recent earthquake or after prolonged heavy rain

If you have cracks you’re uncertain about, photograph them with something for scale (a coin works) and date the photos. Check them again in a few months. If they’re growing, get a structural engineer to look — not a general contractor, a licensed structural engineer. Your state’s board of professional engineers can help you find one in your area.

Homes built before the 1980s in seismically active areas of the U.S. may not have been constructed under modern seismic codes. A seismic retrofit — which involves bolting the house’s wood frame to its foundation and adding structural plywood sheathing — can dramatically improve how a home performs in a major earthquake. The California Earthquake Authority’s Brace + Bolt program and similar programs in other states sometimes offer grants or rebates to help offset the cost. Check with your state’s emergency management agency for current offerings in your region.

A Common Mistake That Causes Preventable Injuries During the Shaking Itself

The instinct to run outside when the ground starts moving is nearly universal. It feels like the right thing to do — get away from the building, get to open space. But in practice, this is one of the most consistent sources of preventable injury during an earthquake. The moment of shaking is precisely when glass is fracturing outward from windows, when roof tiles and exterior wall cladding are falling, when people are least able to keep their footing. The doorframe and the path to the front door are not safe corridors during active shaking.

The guidance that has held up consistently is: drop, cover, hold on. Get under a sturdy table or desk if one is nearby; if not, get against an interior wall away from windows, cover the back of your neck with your hands, and stay there until the shaking completely stops. Only then assess and move toward exits. This isn’t a guarantee — nothing in disaster response is — but it is a measurably better outcome than running through a building while the walls are still moving.

Understanding why people ignore this instruction even when they know it is worth reading — the gap between what people plan to do and what they actually do under sudden stress is significant. 【Explained by a Former Firefighter】Why People Ignore Early Warnings in Disasters covers the behavioral side of this in more depth.

Special Considerations: Children, Elderly Residents, and People with Mobility Limitations

Children need to know what to do independently, because you may not be in the same room when shaking starts. The drop-cover-hold-on protocol is teachable to kids from about age five onward, and practicing it physically — not just talking about it — makes a real difference in whether it happens automatically under stress. The best time to practice is during a calm moment, treating it the way you’d treat a fire drill. Schools in seismically active states hold these regularly; households mostly don’t, and that’s a gap worth closing.

For elderly residents or anyone with limited mobility, the key preparation question is: where are the most dangerous objects in the rooms they use most? If a family member spends most of their time in a specific room, that room gets priority for hazard removal and furniture anchoring. A medical alert device or a charged phone kept within reach is important — after a major earthquake, a person who has fallen or been struck by debris may need to call for help before anyone can reach them.

If anyone in the household uses medical equipment that requires electricity, build that into your power outage plan now rather than after the fact. A portable battery backup that can run essential medical devices through a multi-day outage is available in a range of sizes and prices, and it’s far easier to acquire before an event than after one. Similarly, any prescription medications should have at least a partial supply accessible in an emergency kit — not just in the bathroom cabinet.

For families with pets, the same hazard-reduction principles apply: secure heavy items in spaces the pets use, and make sure pet carriers are accessible rather than buried in storage. 【Explained by a Former Firefighter】Self-Rescue Skills Before Help Arrives covers the period before emergency services reach you — which is precisely when having a working plan for the whole household matters most.

Stay or Go: A Decision Rule for the Aftermath

After shaking stops, you face a real decision: stay in your home or leave. The general rule is: if you can smell gas, see structural damage (significant cracks in load-bearing walls, a shifted foundation, doors and windows that no longer fit their frames), or your local emergency management authority has issued an evacuation order — get out. Don’t wait to see if things settle. Don’t go back to collect belongings until the structure has been assessed.

If none of those conditions apply, sheltering in place is usually better than joining road congestion with tens of thousands of other displaced residents. Roads after a major earthquake may be damaged or blocked, and leaving unnecessarily uses fuel and creates hazards for emergency vehicles. Check your local emergency alert system — signing up in advance rather than during an event is how you receive structured, timely guidance. How Emergency Alerts Work and Why One Channel Is Never Enough explains the different alert channels and why relying on just one is a gap in any plan.

If you do need to evacuate, the considerations change based on conditions outside — including road flooding if the earthquake coincides with wet-season weather. When to Drive Out and When to Abandon Your Car covers the specific judgment calls around vehicle evacuation when conditions on the road are uncertain.

In regions where earthquakes occur alongside seasonal hazards — heavy rain, flooding, landslide risk — the post-earthquake period can compound quickly. Shaking destabilizes saturated slopes. If you live near a hillside and heavy rain follows an earthquake, treat that combination as a serious landslide risk even if no official warning has been issued. When the Ground Speaks: Recognize Landslide Warning Signs gives you the physical cues to watch for.

The One Thing to Do Today — Under Ten Minutes

Walk into your bedroom right now. Look at every object above shoulder height. Identify the tallest, heaviest piece of furniture that isn’t anchored to the wall. That’s your project for this week — not this afternoon, this week. But the walk-through is the ten-minute action for today.

While you’re in there: open your nightstand drawer and ask whether there’s a flashlight in it. Not somewhere in the house — in the drawer within arm’s reach of where you sleep. A small, reliable flashlight kept there means that when the shaking stops at 2 a.m. and the power is out and glass is on the floor, you don’t have to navigate in the dark to find one. That’s a single, specific, cheap change that costs about five minutes and five dollars.

The USGS maintains current information on seismic hazard by region, which is worth knowing for your specific area: USGS Earthquake Hazards Program. If you’re in a zone with significant seismic activity and your home was built before modern codes, the retrofit question is worth looking into seriously — it’s a larger investment, but it’s also the single most durable thing you can do for long-term safety.

Most of what makes a household genuinely better prepared for an earthquake isn’t expensive or complicated. It’s the walk-through that most people haven’t done. Start there.
