Why Earthquake Preparedness Matters

Earthquakes strike without warning. Unlike hurricanes or wildfires, there is no forecast and no evacuation window — just seconds of shaking that can knock over furniture, break gas lines, and cut off power and water for days. Most earthquake injuries happen inside buildings and are caused by falling objects and broken glass, not the ground movement itself. That means the work you do today directly reduces how dangerous the next quake will be for your household.

The goal is not to make your home earthquake-proof, which is nearly impossible in older construction. The goal is to eliminate the most predictable hazards: unsecured furniture, a loose water heater, glass bottles stored at head height, and a family that has never discussed what to do. Each of these can be addressed in a single weekend with basic tools and under two hundred dollars in materials.

Securing Heavy Furniture and Appliances

Falling furniture is the leading cause of earthquake injuries inside the home. Work through this room-by-room checklist:

1. Anchor bookcases, dressers, and wardrobes. Use L-brackets rated for at least 200 lb. Screw one end into a wall stud — use a stud finder, since drywall anchors will pull out — and the other into the back of the furniture frame. Install two brackets per piece, one near each upper corner.
2. Strap your water heater. Many building codes require water heaters to be double-strapped to wall studs with steel plumber tape or purpose-made water heater straps. Retrofit kits cost under 20 dollars at any hardware store. A tipped water heater can sever the gas line and start a fire.
3. Move heavy items from high shelves. Relocate glass containers, ceramics, and heavy books to below waist height wherever possible. Use museum putty or non-slip shelf liner for decorative items that must stay up high.
4. Install cabinet door latches. Fit child-safety latches on kitchen cabinets so they do not fly open and scatter contents. This matters most for cabinets above countertops where people stand.
5. Secure the refrigerator. A standard refrigerator weighs 200 to 300 lb and can slide across the floor or tip forward. An appliance strap kit bolted to a wall stud prevents both.
6. Anchor your television. Flat-screen televisions on stands are a major falling hazard. Use an anti-tip strap to anchor the stand to the wall, or mount the TV directly to the wall with appropriate wall-mount hardware.

Building Your Earthquake Emergency Kit

After a major earthquake, utilities may be out for 72 hours or longer. Store your kit in a waterproof container — a wheeled garbage can with a lid or a large plastic storage tote with latching handles — that is reachable from outside the home in case the structure is damaged or unsafe to enter.

Core supplies per person

• Water: 1 gallon per person per day in sealed food-grade containers. Rotate every 6 months. Do not rely on tap water after a major quake until authorities confirm the supply is safe.
• Food: Non-perishable items your household will actually eat — canned goods, protein bars, dried fruit, nut butter. Include a manual can opener. Prioritize items that require no cooking.
• First aid kit: Bandages, gauze pads, medical tape, antiseptic wipes, pain relievers, and at least a 7-day supply of any prescription medications rotated to stay current.
• Flashlights and spare batteries: One per person. LED headlamps are more useful than handheld models when both hands are needed to move debris or help someone.
• Portable power bank: Keep it fully charged. A hand-crank or solar model is a useful backup when grid power is out for multiple days.
• Cash in small bills: ATMs and card readers stop working during extended power outages. Keep at least 50 dollars in small denominations.
• Document copies: Photocopies of IDs, insurance policies, medication lists, and emergency contacts in a waterproof bag inside your kit.
• N95 dust masks: Earthquakes generate fine concrete and drywall dust that damages lungs. Pack one mask per person.
• Adjustable wrench or pliers: For shutting off the gas valve and water main at their supply shutoffs if you detect a leak or damage.

Creating a Family Communication Plan

Cell networks typically become congested or overloaded within minutes of a major earthquake. Your family members may be at different locations — work, school, a friend's house — when shaking occurs. Agree on the specifics below before an earthquake; they cannot be arranged during one.

1. Designate an out-of-area contact. Local lines are congested after a big quake; calling or texting a relative in another city or state is often easier than reaching someone in the same neighborhood. Every household member should have this person's number written on a wallet card and memorized.
2. Agree on two meeting places. Choose one location near your home, such as the sidewalk in front of a neighbor's house two doors down, and one farther away, such as a library or community center several blocks away, in case the immediate area is damaged or inaccessible.
3. Know your children's school protocol. Most districts have a formal earthquake reunification procedure requiring parents to show photo ID before a child is released. Know where your school's reunification site is and keep a copy of the process in your emergency kit.
4. Text first, call second. SMS messages pass through congested networks far more reliably than voice calls. Teach every family member, including older children, to send a brief text confirming their location and status before attempting a voice call.
5. Enable Wireless Emergency Alerts on all phones. These alerts push automatically to all phones in an affected area regardless of carrier. Confirm this setting is on under each phone's notification or emergency alert settings.

Strengthening Your Home's Structure

Furniture and kit preparation can be completed in a weekend. Structural improvements are more involved, but in high-seismic zones they can be the difference between a home that is livable after a major quake and one that must be demolished. The three most common structural vulnerabilities in older homes are:

• Cripple wall failure. Homes built before the 1980s in North America often sit on a short wood-framed wall between the concrete foundation and the first floor. These cripple walls collapse sideways during strong shaking unless braced with plywood sheathing. A licensed contractor can assess and brace a cripple wall in one to two days. State and local programs in high-seismic areas often provide grants or low-interest loans for this type of retrofit.
• Unbolted foundations. A house that is not bolted to its foundation can slide off during strong shaking. Foundation bolting typically costs between 1,500 and 5,000 dollars depending on the size of the home and the accessibility of the crawl space.
• Soft-story construction. Multi-unit buildings with a large open ground floor — a parking garage or retail space — are vulnerable to collapse because the upper floors have no adequate lateral support. Many cities with high seismic risk now mandate retrofits for this building type; check with your local building department.

Ask a licensed structural engineer or a contractor experienced in seismic retrofits for a home assessment. Many local building departments offer free printed guides on what to look for and how to find qualified contractors in your area.

What to Do During an Earthquake

When shaking starts, your useful decision window is roughly one to two seconds before furniture begins to move. Your response needs to be instinctive, which is why practicing it matters. The correct action depends on where you are when shaking begins.

Indoors

• Drop, Cover, and Hold On. Drop to hands and knees, move under a sturdy table or desk, and hold on with both hands until shaking completely stops. If no table is nearby, move against an interior wall away from windows and cover your head and neck with your arms.
• Stay away from windows. Glass can shatter and project outward over a wide area, creating a hazardous zone you cannot anticipate.
• Do not run outside during shaking. Most injuries happen when people move during the event and are struck by falling objects or lose their footing on an unstable floor. Stay in place until shaking fully stops.
• Do not use elevators. Use stairs only after shaking has fully stopped and you have confirmed they are structurally intact before descending.

Outdoors

• Move away from buildings, streetlights, and overhead power lines. Brick facades and window glass can fall outward. Once clear, drop to your knees in an open area and cover your head with your arms until shaking stops.

In a vehicle

• Pull over to a clear area away from overpasses, bridges, utility poles, and buildings. Stay inside with your seatbelt fastened until shaking stops. Afterward, drive cautiously and watch for damaged roads, downed cables, and debris.

After the Earthquake: Immediate Safety Checks

The first hour after shaking stops is when many secondary injuries and post-quake fires occur. Work through this checklist before re-entering your home or resuming normal activity:

1. Check yourself and others for injuries. Provide basic first aid where you can and call emergency services for serious injuries. Do not move someone who may have a spinal injury unless they are in immediate life-threatening danger.
2. Inspect for gas leaks. If you smell gas, hear a hissing or blowing sound, or see a damaged gas line, open windows, leave immediately, and call your gas utility emergency number from outside. Do not operate any electrical switches on your way out.
3. Check for visible structural damage. Walk around the outside of the building and look at the foundation, exterior walls, and chimney before re-entering. Diagonal cracks radiating from window or door corners, a visibly leaning chimney, or a shifted roofline are warning signs to stay out and call a structural engineer.
4. Turn off water if pipes appear damaged. Locate your main water shutoff — usually near the water meter at the street or in a basement utility area — and close it if you see dripping, hear running water inside walls, or find the water is discolored from the tap.
5. Expect and prepare for aftershocks. Aftershocks can occur minutes to many days after the main event and can be strong enough to bring down already-weakened structures. Stay alert and be ready to Drop, Cover, and Hold On again at any moment.
6. Avoid tap water until officially cleared. Earthquakes can fracture water mains and contaminate the municipal supply. Wait for confirmation from your water utility before drinking, cooking with, or bathing in tap water. Use your stored supply in the meantime.
