Earthquake Emergency Plan: Protect Your Home, Family & Property (2026 Guide)
Over 20,000 earthquakes hit the United States every year. Most are minor, but a magnitude 6.0+ can destroy homes in seconds — collapsing walls, rupturing gas lines, breaking water mains, and triggering fires that cause more damage than the quake itself.
If you live in California, the Pacific Northwest, Alaska, Hawaii, Oklahoma, Tennessee, South Carolina, or anywhere near a fault line, an earthquake emergency plan isn’t optional. This guide covers everything: before, during, and after — plus how modern security technology changes the game.
US Earthquake Risk by Region
| Risk Level | States/Regions | Notable Fault Lines | Last Major Quake |
|---|---|---|---|
| 🔴 Very High | California, Alaska, Hawaii | San Andreas, Cascadia, Hayward | Ridgecrest 7.1 (2019), Anchorage 7.1 (2018) |
| 🔴 High | Oregon, Washington, Utah, Nevada | Cascadia Subduction Zone, Wasatch | Magna UT 5.7 (2020) |
| 🟡 Moderate | Oklahoma, Tennessee, Missouri, South Carolina | New Madrid, Eastern TN Seismic Zone | Oklahoma 5.8 (2016) |
| 🟢 Low (not zero) | Most eastern states, Texas, Florida | Various minor faults | Virginia 5.8 (2011) — felt in 22 states |
Key fact: The Cascadia Subduction Zone (Pacific Northwest) is overdue for a magnitude 9.0+ megaquake that would devastate Oregon and Washington. FEMA considers this one of the highest-risk natural disaster scenarios in the US.
Before the Earthquake: Preparation Checklist
Secure Your Home (The #1 Life-Saver)
| Item to Secure | Why It Matters | How to Fix | Cost |
|---|---|---|---|
| Water heater | Can rupture gas line, start fire | Earthquake straps to wall studs | $15-30 |
| Heavy furniture (bookcases, dressers) | Falls and crushes people (leading injury cause) | L-brackets or furniture straps to studs | $5-15 each |
| TV/monitors | Flatscreens become projectiles | Anti-tip straps or wall mount | $10-40 |
| Gas appliances | Ruptured gas = explosion/fire risk | Flexible gas connectors | $20-50 |
| Kitchen cabinets | Dishes/glasses become shrapnel | Child-proof latches on upper cabinets | $10-20 |
| Mirrors/heavy art | Falls from walls onto sleeping areas | Closed hooks, museum putty, move away from beds | $5-15 |
| Foundation | Older homes slide off foundation | Cripple wall bracing, foundation bolting | $3,000-7,000 (pro) |
Build an Earthquake Kit
After a major earthquake, you may have no water, power, gas, or emergency services for 72+ hours. FEMA recommends supplies for at least 3 days; earthquake-prone areas should plan for 7-14 days.
| Category | Items | Quantity (Family of 4) |
|---|---|---|
| Water | 1 gallon per person per day | 28 gallons minimum (7-day supply) |
| Food | Non-perishable, no-cook foods (canned goods, protein bars, dried fruit, peanut butter) | 7-day supply per person |
| First aid | Bandages, antiseptic, pain relievers, prescription meds (2-week supply), dust masks | 1 comprehensive kit |
| Light | Flashlights, headlamps, batteries, hand-crank lantern | 1 per person + extras |
| Communication | Battery/hand-crank radio (NOAA), charged power banks, whistle | 1 radio, 2 power banks |
| Tools | Wrench (to shut off gas), pry bar, work gloves, duct tape, plastic sheeting | 1 set in accessible location |
| Sanitation | Garbage bags, toilet bags, hand sanitizer, wet wipes, bleach | 7-day supply |
| Documents | Insurance policies, IDs, bank info in waterproof container or cloud backup | 1 grab-bag |
| Cash | Small bills — ATMs and card readers won’t work without power | $200-500 |
Storage tip: Keep kits in multiple locations — one inside (accessible closet, not basement), one in the garage, one in the car. After a quake, you may not be able to access parts of your home.
Create a Family Communication Plan
- Out-of-area contact: Pick a relative/friend in another state as a central check-in point (local lines may be jammed)
- Meeting points: Establish two — one near your home (front yard, neighbor’s driveway) and one outside your neighborhood (school, park, church)
- Text, don’t call: Text messages get through when voice calls can’t during emergencies
- ICE contacts: Program “ICE” (In Case of Emergency) numbers in every family member’s phone
- Kids’ school plan: Know your children’s school earthquake and reunification procedures
During the Earthquake: Drop, Cover, Hold On
| Where You Are | What to Do | What NOT to Do |
|---|---|---|
| Indoors | DROP to hands and knees, take COVER under a sturdy desk/table, HOLD ON until shaking stops | Don’t run outside (falling debris kills more than collapsed buildings). Don’t stand in a doorway (myth) |
| In bed | Stay in bed, cover your head with a pillow. Roll off only if directly under a heavy hanging object | Don’t run — broken glass on dark floors causes severe foot injuries |
| Outdoors | Move to an open area away from buildings, trees, power lines, signs | Don’t run into a building |
| Driving | Pull over away from bridges, overpasses, power lines. Stay in car with seatbelt on | Don’t stop on or under a bridge or overpass |
| In a store | Drop and take cover away from shelves, windows, heavy displays | Don’t rush for exits (stampede risk) |
| Near the coast | After strong shaking (20+ seconds), move to high ground immediately — tsunami may follow | Don’t wait for an official warning — shaking IS the warning |
The “Triangle of Life” is a myth. Every major emergency management agency (FEMA, Red Cross, USGS) recommends Drop, Cover, Hold On. Don’t lie next to furniture hoping for a protective triangle — get under it.
After the Earthquake: First 24 Hours
Immediate Actions (First 10 Minutes)
| Priority | Action | Why |
|---|---|---|
| 1 | Check yourself and family for injuries | Adrenaline masks pain — check everyone carefully |
| 2 | Check for gas leaks (smell, hissing) | If you smell gas: shut off main valve, open windows, evacuate. Do NOT use matches, light switches, or phones near leak |
| 3 | Check for structural damage | Look for cracks in walls/foundation, chimney damage, shifted walls. If structure seems unsafe, evacuate |
| 4 | Turn off utilities if damaged | Gas valve (if leak), water main (if broken pipes), electricity (if damage/flooding) |
| 5 | Put on shoes and sturdy clothing | Broken glass, debris, nails everywhere after a quake |
| 6 | Check on neighbors (especially elderly) | They may be trapped, injured, or unable to call for help |
| 7 | Text your out-of-area contact | “We’re OK” or “Need help at [address]” — keep it short |
| 8 | Turn on battery radio for updates | Learn about aftershocks, tsunami warnings, emergency shelters |
Aftershock Warning
Aftershocks can be nearly as strong as the main quake and continue for days, weeks, or even months. After a magnitude 7.0, expect hundreds of aftershocks including several magnitude 5.0+. Each aftershock can cause additional damage to already-weakened structures.
Stay out of damaged buildings even if they look OK from outside. Weakened structures can collapse from aftershocks that wouldn’t damage an intact building.
How Home Security Systems Help Before, During & After Earthquakes
Modern security systems aren’t just for burglars — they provide critical safety features during natural disasters:
| Security Feature | Earthquake Benefit | Systems That Have It |

Earthquake Insurance: What You Need to Know
| Fact | Detail |
|---|---|
| Standard homeowner’s insurance covers earthquakes | ❌ NO — earthquake damage is excluded from most standard policies |
| Average earthquake policy cost (California) | $800-5,000+/year depending on location, home age, construction type |
| Typical deductible | 10-25% of dwelling coverage (on a $500K home, that’s $50K-125K out of pocket) |
| California Earthquake Authority (CEA) | State-run program offering standardized earthquake insurance — most CA residents’ best option |
| What’s covered | Dwelling, personal property (limited), loss of use/temporary housing |
| What’s NOT covered | Landscaping, pools, fences, masonry veneer, external features |
Documentation tip: Before an earthquake hits, walk through your home with your phone and record video of every room, every possession, every serial number on electronics. Upload to cloud storage. This makes insurance claims dramatically faster and more complete. Security cameras with cloud recording serve as continuous documentation.
Earthquake-Proofing by Home Type
| Home Type | Biggest Vulnerability | Priority Fix | Estimated Cost |
|---|---|---|---|
| Pre-1940 unreinforced masonry | Brick walls can collapse entirely | Seismic retrofit (steel reinforcement) | $10,000-30,000 |
| 1940s-1970s raised foundation | Cripple wall collapse — house slides off foundation | Cripple wall bracing + foundation bolting | $3,000-7,000 |
| 1970s-1990s soft-story (apartments) | Open ground floor (parking) collapses under upper floors | Soft-story retrofit (steel moment frame) | $50,000-200,000 |
| Modern wood-frame (post-2000) | Generally good seismic performance | Secure water heater, strap furniture, add sensors | $50-200 |
| Mobile/manufactured home | Can shake off supports entirely | Earthquake bracing system (EBS) | $3,000-6,000 |
ShakeAlert: America’s Earthquake Early Warning System
The ShakeAlert system (operated by USGS) sends earthquake warnings to smartphones seconds before shaking arrives. It’s currently active in California, Oregon, and Washington.
- How it works: Sensors near the epicenter detect the faster P-waves and send alerts before the destructive S-waves arrive
- How much warning: Seconds to tens of seconds — enough to Drop, Cover, Hold On; stop an elevator; pull over; move away from hazards
- How to get alerts: Built into Android (automatic in CA/OR/WA), iOS earthquake alerts, and the MyShake app
- Limitation: No warning if you’re at the epicenter — the alert and shaking arrive simultaneously
Frequently Asked Questions
What magnitude earthquake can damage a house?
Magnitude 5.0+ can cause moderate damage (cracked walls, broken chimneys, fallen objects). Magnitude 6.0+ can cause severe structural damage. Magnitude 7.0+ can destroy buildings. However, damage depends heavily on distance from epicenter, soil type, building construction, and duration of shaking. A 5.5 on soft soil can damage more than a 6.0 on bedrock.
Should I stand in a doorway during an earthquake?
No — this is an outdated myth. In modern homes, doorways are no stronger than any other part of the house. Get under a sturdy desk or table instead. The doorway myth comes from old adobe construction where the door frame was the strongest structural element.
How do I shut off my gas after an earthquake?
Locate your gas meter (usually outside). Use an adjustable wrench to turn the valve 1/4 turn until it’s perpendicular to the pipe. Only shut off gas if you smell gas or suspect a leak. Once you shut it off, only the gas company can turn it back on — this can take days after a major quake.
Will my security system work after an earthquake?
Systems with cellular backup and battery backup will continue working even if power and internet go down. Abode, Ring, and SimpliSafe all have battery backups lasting 24+ hours. Water leak sensors and smoke detectors will continue monitoring for secondary damage (burst pipes, fires).
Do I need earthquake insurance?
If you live in California, the Pacific Northwest, or any high-risk seismic zone, yes. Standard homeowner’s insurance does NOT cover earthquake damage. The California Earthquake Authority (CEA) offers policies starting around $800/year. High deductibles (10-25%) mean you’ll pay the first $50K-125K on a $500K home, so earthquake insurance is really for catastrophic loss, not minor damage.
How can I protect my home from earthquake damage on a budget?
Start with the highest-impact, lowest-cost fixes: strap your water heater ($15), secure heavy furniture ($5-15 each), add child-proof latches to upper cabinets ($10), and install water leak sensors to catch burst pipes fast ($35 each). Total cost under $150 for the basics. Foundation bolting ($3,000-7,000) is the big investment but can prevent catastrophic loss.

This is very useful and I would be sharing this with my friends. A 72 hour kit is very handy and I would definitely be starting up with my own version of that so I would know that we are ready to face everything.
