In well-built modern structures, major earthquakes rarely cause buildings to collapse outright. What they do — consistently, predictably — is cause things inside buildings to fall, break, and injure the people who live there.
Bookcases. Water heaters. Kitchen cabinets. Heavy pictures. Televisions. Appliances. The things that hurt people in earthquakes are usually the things that were sitting in their homes, unsecured, for years before the shaking started.
The good news is that this is one of the most actionable parts of earthquake preparedness. You don’t need to rebuild your house. You need a weekend, some basic hardware, and a systematic walk-through of your space.
The Most Important Room: Your Bedroom
Start here. You spend roughly eight hours a day unconscious in your bedroom, with no ability to react when shaking starts. Injuries in bedrooms during earthquakes are disproportionately high for exactly this reason.
Before you touch anything else, address your bedroom:
- Secure or remove anything heavy above where you sleep. Heavy picture frames, shelves with books, ceiling fans, and hanging plants all become projectiles. If it’s over your bed and it’s heavy, it needs to be moved or anchored.
- Anchor your dresser and any tall furniture to the wall. Furniture straps cost $10–15 at any hardware store and take 20 minutes to install. A tall dresser falling on someone in their sleep can be fatal.
- Keep shoes near your bed. Post-earthquake, floors are covered in broken glass and debris. Being able to put shoes on before walking through your home is a meaningful safety measure. A small bag with shoes and a flashlight near your bed is a habit worth building.
Furniture Anchoring Throughout the House
Walk through your home with a critical eye for anything tall, heavy, or top-heavy. This includes:
- Bookcases and bookshelves
- Filing cabinets
- China hutches and display cabinets
- Armoires and wardrobes
- Tall storage shelves in garages and laundry rooms
The anchoring method is the same for all of them: furniture straps or L-brackets that connect the top of the furniture to a wall stud. Anchor into the stud, not just the drywall — drywall anchors will pull free under the forces of a major earthquake. A stud finder (about $20) and a drill are the only tools you need.
If you rent and can’t put holes in the walls, tension-mounted furniture anchors that use pressure rather than screws are available and work reasonably well.
The Kitchen: Latches and Storage Strategy
Kitchen cabinets will open and empty their contents during significant shaking. Heavy dishes, glass jars, and canned goods falling from overhead cabinets cause lacerations and blunt force injuries.
- Install cabinet latches. Spring-loaded magnetic or touch-release cabinet latches keep doors closed during shaking while remaining easy to open in normal use. A set covers most kitchens for under $30.
- Store heavy items low. Rethink what lives where. Cast iron pans, heavy appliances, and large jars belong in lower cabinets or on lower shelves — not overhead.
- Move breakable items off open shelves. Decorative dishes, glassware, and fragile items on open shelves are the first things to go. Storing them in latched cabinets dramatically reduces breakage and injury risk.
Water Heater and Large Appliances
An unsecured water heater is one of the most significant — and most ignored — earthquake hazards in Pacific Northwest homes. A conventional tank water heater weighs 150–300 lbs when full and will topple in a major earthquake, potentially rupturing gas lines, water lines, or both.
Securing a water heater requires two heavy-duty straps — one in the upper third and one in the lower third of the tank — anchored to wall studs. This is a two-hour project for a handy homeowner or a short visit from a plumber. Oregon and Washington building codes require water heater strapping; if your home pre-dates enforcement or was built without it, check and fix it.
Gas appliances: know where your main gas shutoff is and how to turn it off. After a major earthquake, if you smell gas, shut it off. You’ll need a wrench to do it — keep one near the meter. Do not turn the gas back on yourself; contact your utility.
Your Home’s Structure: What to Know
Content securing is something you can do this weekend. Structural retrofitting is more involved, but worth understanding.
Cripple wall bracing: Many older PNW homes (pre-1980s) were built on short wood-framed walls (cripple walls) between the foundation and the first floor. These walls are a known structural vulnerability in earthquakes. Oregon and Washington offer resources on cripple wall retrofitting — search your state’s seismic hazard program for guidance and, if your home applies, get an evaluation.
Soft-story buildings: Multi-story buildings where the ground floor is significantly more open than upper floors (often due to garages or large retail spaces) are structurally vulnerable. If you live in such a building, find out whether it has been seismically evaluated.
A One-Weekend Project Plan
You don’t have to do all of this in a single afternoon. A practical sequence:
- Day 1, 2 hours: Bedroom. Anchor all tall furniture. Move heavy items from over the bed. Put shoes and a flashlight where you sleep.
- Day 1, 1 hour: Kitchen. Install cabinet latches. Relocate heavy overhead items to lower storage.
- Day 2, 2 hours: Rest of the house. Work room by room on tall and heavy furniture.
- Separate day: Water heater straps. Check the gas shutoff. Locate the main water shutoff as well.
The total materials cost for a typical home is $75–$150. The time investment is meaningful but finite. And unlike many aspects of earthquake preparedness, the benefit is immediate — whether or not a major event ever happens, a secured home is a safer home.
