Earthquake Safety & First Aid Kit Guide (2026) | Coast2Coast

California sits on top of more than 15,000 known faults, and the state records thousands of earthquakes every year, most too small to notice, some not. There’s no warning system that gives you more than a few seconds of lead time, which means real earthquake preparedness comes down to two things: knowing exactly what to do the moment the ground starts moving, and having an earthquake emergency kit stocked and stored before you ever need it. This guide covers both, sourced from FEMA, the CDC, USGS, and California’s own emergency management agencies.

Key Takeaways

• The only response recommended by FEMA, the CDC, USGS, and the American Red Cross during an earthquake is Drop, Cover, and Hold On. Running outside, standing in a doorway, and the “triangle of life” are discredited or outdated advice.
• Most earthquake injuries come from falling or flying objects, not collapsing buildings. Securing heavy furniture with anti-tip anchors prevents injuries before the shaking ever starts.
• Guidance on emergency supplies varies: FEMA’s baseline is 3 days, most earthquake kits are built for 3 to 7 days, and Los Angeles guidance recommends preparing for 7 to 10 days of self-sufficiency.
• A basic first aid kit isn’t built for earthquake injuries. Your earthquake kit needs trauma-grade bleeding control, splinting materials, dust masks, and enough supplies for several days.
• Earthquake kits should include first aid, lighting, and sanitation supplies together, not just bandages. Equipment without training only gets you halfway, which is why hands-on first aid and CPR training completes the kit.

During the Earthquake: Drop, Cover, and Hold On

Every major emergency management agency, FEMA’s Ready.gov, the CDC, USGS, and the American Red Cross, recommends the same response the moment you feel shaking or get an earthquake alert:

1. Drop onto your hands and knees before the earthquake knocks you down.
2. Cover your head and neck with your arms, and get under a sturdy table or desk if one is nearby. If there’s no shelter, crawl next to an interior wall, away from windows.
3. Hold on to your shelter, or to your own head and neck, until the ground stops moving completely.

• If you’re in bed, stay there and cover your head with a pillow.
• If you’re in a car, pull over away from overpasses, bridges, and power lines, and stay inside with your seatbelt on.
• If you’re outdoors, move to open ground away from buildings, trees, and power lines, then drop and cover anyway, since falling debris is still a risk even without a building overhead.

Earthquake Myths That Can Get You Hurt

Standing in a doorway does not protect you. This was reasonable advice for older adobe construction, but in a modern building a doorway isn’t structurally stronger than the rest of the room, and it doesn’t shield you from falling and flying objects, the leading cause of earthquake injury.

The “triangle of life” is not a credible method. This advice, which circulated widely online, tells people to curl up next to large furniture instead of taking cover under it. It’s been directly discredited by structural engineers and emergency management experts.

Running outside during an earthquake is dangerous, not safer. The ground itself is moving, glass and debris are falling from buildings, and you’re far more likely to be injured trying to run than staying put and taking cover.

After the Shaking Stops

• Check yourself first, then the people around you. You can’t help anyone if you’re injured and don’t realize it.
• Expect aftershocks, and be ready to drop, cover, and hold on again.
• Check for gas leaks immediately. Fires are one of the most significant risks after a major earthquake, usually from ruptured gas lines. Natural gas has a distinctive rotten-egg smell; if you notice it, evacuate, shut off your gas at the main valve if you know how, and call your gas company from outside. Don’t use matches, lighters, or light switches. Keep a fire extinguisher in an accessible spot and know how to use it, since a small fire caught early is very different from one that isn’t.
• Check for other hazards: damaged water lines, downed power lines, and structural damage like cracked walls, before moving around freely.
• If your building is damaged, get out and stay out until it’s inspected. Don’t use elevators.
• If you’re near the coast and the shaking was long or severe, California’s coastal cities, including Los Angeles, Long Beach, and San Diego, carry tsunami risk from major offshore earthquakes. Move inland or to higher ground immediately rather than waiting for an official warning.
• If you’re trapped, protect your mouth from dust, tap on a pipe or wall to signal your location, and use a whistle rather than shouting.

Before the Earthquake: Secure Your Space

Most earthquake injuries come from things falling on people, which means some of the highest-value preparedness work happens long before any shaking starts. Secure heavy furniture like bookcases, dressers, and water heaters to wall studs with anti-tip anchors or straps. Move heavy and breakable items to low shelves, and keep beds and seating areas away from tall furniture and large windows. Cabinet doors can fly open during a strong earthquake and empty their contents across the floor, so consider latches on upper kitchen cabinets. Securing your space costs little and directly prevents the most common category of injury.

Make a Family Communication Plan

A major earthquake can knock out local phone lines and overload cell networks exactly when family members are trying to reach each other. Create a family communication plan before an earthquake occurs, not after. This is the part of disaster preparedness that costs nothing and gets skipped most often.

• Pick two meeting spots: one near home, and one outside your neighborhood in case family members can’t get back.
• Designate an out-of-state contact everyone checks in with, since long-distance calls and texts often go through when local lines fail.
• Make sure every person in the household, including kids, knows the plan and has the contact’s number written down somewhere that isn’t just a phone.
• Texts usually get through before calls do after a disaster, so agree in advance that a short text is the first move.
• While you’re at it, walk the household through where the fire extinguisher, gas shutoff, and main emergency kit are stored, so any family member can find them alone. Emergency preparedness that lives in one person’s head isn’t a plan; it’s a single point of failure.

Water and Food: How Much Your Emergency Kit Needs

Water is the single most important item in any earthquake emergency kit. The standard baseline is one gallon of water per person per day for drinking and basic sanitation, which means storing three gallons of water per person for a 72-hour supply. Each person in your household needs their own count, including kids. That’s the floor, not the ceiling: most earthquake kits are built for 3 to 7 days of emergency supplies, Los Angeles County guidance currently recommends supplies for up to 10 days, and LA’s own utility guidance has recommended preparing for at least a week of self-sufficiency per person. After a major earthquake, water systems can take longer to repair than anyone plans for.

For emergency food, choose nonperishable food that doesn’t increase thirst: canned fruit, canned beans, energy bars, and other food items that need no cooking. Commercially packaged emergency food and water is often rated to last up to five years, but check dates on anything you assemble yourself and refresh stored water every six months. Keep a manual can opener with the food supplies, plus purification tablets as a backup in case your main drinking water supply is compromised. Store extra emergency food for pets if you have them.

First Aid Supplies: What to Pack in Your Earthquake Emergency Kit

A basic drugstore kit is built for paper cuts and headaches, not for what earthquakes actually produce: lacerations from broken glass, crush injuries, fractures from falling debris, and burns from damaged gas lines. The first aid section of your earthquake emergency kit reduces infection risk after injuries and lets you treat multiple people over several days. Here’s what to pack:

Wound care and bleeding control:

• Pain relievers and gauze pads, the two items no kit should be without
• Assorted adhesive bandages and sterile gauze in multiple sizes
• Rolled gauze and adhesive cloth tape
• Antiseptic wipes and antibiotic ointment, which reduce infection risk when wounds can’t be professionally cleaned for days
• At least two large trauma dressings and triangular bandages for slings
• Elastic bandages for compression and support
• A commercial tourniquet, only if you’ve had training on using one

Tools:

• Trauma shears, tweezers, and safety pins
• Duct tape, which reinforces bandages and turns a piece of cardboard into a workable splint

Medications:

• Acetaminophen and ibuprofen in adult and child doses
• Antihistamines and oral rehydration salts
• A several-day supply of personal prescriptions

Protective items:

• Nitrile gloves and dust masks or N95 respirators, since structural damage fills the air with concrete dust
• Instant cold packs and emergency blankets (the mylar type)
• Safety goggles

CPR readiness:

• A compact CPR barrier mask, the same kind taught in a standard CPR/AED course

Know your limits with any kit. Don’t move someone with a suspected spinal injury unless they’re in immediate danger like fire or further collapse, and tuck a short written action plan inside the kit for when stress clouds your thinking.

Emergency Supplies Beyond First Aid

Earthquake kits should include first aid, lighting, and sanitation supplies as one system, because injuries are only part of what the days after a quake demand. Round out your emergency supplies with:

• Lighting and power supplies: a headlamp per person (headlamps beat handheld flashlights when you’re treating someone), light sticks as a no-battery backup, extra batteries stored outside their devices to prevent corrosion, a hand crank or battery radio for official updates, and a power bank to keep your cell phone alive. A hand crank radio doubles as a phone charger in some models, and light sticks are safe around suspected gas leaks where anything with a spark isn’t.
• Tools: a multi-tool, a wrench for the gas shutoff, work gloves, and plastic sheeting or a tarp for shelter and dust barriers. These tools support treatment directly, since you can’t help anyone you can’t safely reach.
• Sanitation supplies: heavy-duty plastic bags, hygiene basics, and hand sanitizer for each person.
• Documents and cash: a water resistant pouch with copies of important documents (ID, insurance, medication lists, emergency contacts) plus small bills in cash, since card readers and ATMs need power.
• Personal items: spare eyeglasses, a change of clothes, and a sleeping bag or warm blanket per person. Personal items are the easiest category to forget and the one every person in the household needs individually. A sleeping bag matters more in colder regions and mountain areas.
• Sturdy shoes and work gloves under your bed, since broken glass on the floor at night is one of the first hazards after an earthquake.

Where to Store Your Earthquake Emergency Kit

A perfectly packed emergency kit stored in the wrong place is worthless if fallen furniture blocks the room it’s in. Distribute your emergency supplies so at least one kit stays within reach no matter which part of the home is blocked.

• Home: keep the main earthquake bag or bin in a low, secure, convenient location near a common exit, like a ground-floor hallway closet. Easy access matters more than tidiness; don’t bury your emergency kit behind seasonal storage where access takes ten minutes of digging.
• Bedroom: a small under-bed pouch with sturdy shoes, a flashlight, and gloves covers the first minutes of a night-time earthquake for each person.
• Car: a smaller emergency kit with water pouches, snacks, a blanket, and a phone charger belongs in every car, since a quake can strike while you’re on the road or keep you from getting home. Heat degrades supplies faster in a car, so check your car kit more often.
• Go bag: if you need to evacuate, a backpack-style go bag you can grab and carry beats a heavy bin. Pack your go bag with the essentials one person would want for 72 hours away from home, and make an earthquake bag for each person in the household rather than one shared bag nobody can lift.
• Coverage: aim for at least one kit per person or small group across your household, so nobody is cut off from essential emergency supplies if part of the home becomes blocked.

Special Considerations for Kids, Older Adults, and Pets

Earthquakes don’t affect everyone in a household the same way, and your earthquake emergency kit should account for that. The base supplies above cover a healthy adult; these additions to the kit cover everyone else.

• Children need pediatric pain relievers with weight-based dosing clearly labeled, plus a small comfort item packed with their supplies.
• Older adults need extra prescription medications (especially cardiac and blood pressure), backup eyeglasses, hearing-aid batteries, and medication schedules in large print added to the kit.
• Chronic conditions need specific planning: spare inhalers, glucose tablets, an insulated pouch for insulin, and copies of care plans.
• Pets need several days of food, collapsible bowls, a leash, vaccination records, and basic pet supplies, plus simple tools like a muzzle or carrier if you’d need to move an injured animal.

Keeping Your Emergency Kit Ready

An unmaintained emergency kit gives you false confidence. Check your earthquake emergency kit at least annually, and every six months for anything perishable: water, food, medications, and batteries. Extra batteries drain even in storage, so test them on each check and keep extra batteries in their original packaging until needed. Rotate stored food into regular meals before expiry and replace it with fresh supplies. Mark the container with the last inspection date and the next one, so it’s obvious at a glance when the kit is due. After any real earthquake or drill, restock any emergency supplies you used and add whatever the experience showed was missing. Preparing once and forgetting isn’t emergency preparedness; keeping the kit current is.

A quick semi-annual checklist: confirm water and food dates, swap in extra batteries where needed, test the hand crank radio and flashlights, verify every family member still knows where each earthquake bag is and has clear access to it, and check that tools like the gas wrench and work gloves haven’t wandered off to the garage toolbox. Ten minutes twice a year is all it takes to prepare properly.

What Real Earthquakes Show

The 1989 Loma Prieta earthquake, magnitude 6.9, caused 63 deaths and 3,757 injuries across the San Francisco Bay Area and Santa Cruz region. The 2014 South Napa earthquake in Northern California sent more than 87 patients to a single hospital in the hours after the quake. Neither event waited for emergency services to catch up before people needed care. The gap between the ground settling and help arriving is exactly what a stocked kit and basic treatment skills are meant to cover.

Common Earthquake Injuries and the Skills That Matter

• Cuts and bleeding from broken glass are extremely common. Controlling bleeding with direct pressure is one of the most immediately useful skills after a quake.
• Fractures and sprains from falling objects usually need to be immobilized in the position found, using whatever sturdy material is available, not straightened.
• Cardiac events can be triggered by the stress and exertion of a major earthquake. Immediate CPR can double or triple survival chances, and an ambulance may take far longer than usual when roads are blocked and emergency services are overwhelmed.
• Burns from ruptured gas lines or damaged appliances need cool water and a covering, never ice, which worsens the damage.

Practice Actually Matters

Reading about Drop, Cover, and Hold On and doing it under pressure are different things. The Great California ShakeOut, held every October, is a free statewide drill that millions of people use to build the muscle memory for those first few seconds of a real earthquake emergency. It’s also a natural annual trigger to check your kit, refresh emergency supplies, prepare replacements for anything expired, and walk through your family communication plan together. Earthquake preparedness is a habit, not a purchase, and the households that prepare on a schedule are the ones whose kits actually work when tested.

Training Completes the Kit

Everything above assumes you can act on your own knowledge before help arrives. After a major earthquake, that window can stretch from hours to days: roads get blocked, emergency call volumes spike, and crews are spread across an entire region at once. For however long that takes, you and the people near you are the only response available.

Coast2Coast First Aid & Safety offers hands-on CPR, AED, and emergency response training across California, including Los Angeles, Long Beach, San Diego, Sacramento, and San Jose. Our full course lineup covers the skills that turn a stocked emergency kit into a real capability, and you can find your nearest California training location to prepare before the next drill, or the next real one.

Frequently Asked Questions

Question 1: How much water should I store for an earthquake?

Answer: One gallon per person per day, which works out to three gallons per person for a 72-hour supply. That’s the baseline; most earthquake kits are built for 3 to 7 days, and Los Angeles guidance recommends preparing for 7 to 10 days of self-sufficiency. Refresh stored water every six months and keep purification tablets as a backup.

Question 2: What’s the difference between a basic first aid kit and an earthquake emergency kit?

Answer: A basic kit handles minor cuts and headaches. An earthquake emergency kit needs trauma-grade bleeding control like large dressings and a tourniquet, splinting materials, dust masks, pain relievers and gauze pads in quantity, and enough emergency supplies to treat several injuries across several days without restocking.

Question 3: Is standing in a doorway the safest place during an earthquake?

Answer: No. In modern buildings a doorway offers no more structural protection than the rest of the room and doesn’t shield you from falling objects, which cause most earthquake injuries. Drop, Cover, and Hold On under a sturdy table or against an interior wall is the current recommendation from FEMA, the CDC, and USGS.

Question 4: How often should I check my earthquake emergency kit?

Answer: At least once a year for the full kit, and every six months for anything perishable: water, food, medications, and batteries. Mark the container with your last check date. Commercially packaged emergency food and water can last up to five years, but self-assembled supplies expire much sooner.

Question 5: Why do I need a family communication plan if everyone has a cell phone?

Answer: Because local phone lines and cell networks are often overloaded or down after a major earthquake, exactly when everyone tries to call at once. A plan with two meeting spots and an out-of-state contact gives your family a way to reconnect that doesn’t depend on local networks working.

Question 6: Should I run outside if an earthquake starts while I’m inside?

Answer: No. The ground is moving and glass and debris are falling from buildings, so you’re more likely to be injured running than staying put. Drop, cover, and hold on until the movement stops completely.

Question 7: Do supplies matter if nobody in the house has first aid training?

Answer: Supplies without training only get you partway. Knowing how to control bleeding, immobilize a fracture, recognize shock, and perform CPR is what determines whether the contents of your kit actually help someone. A hands-on first aid and CPR course covers exactly these skills, and it pairs naturally with building the kit itself.
