Before — Prepare Your Home & Family

Most earthquake injuries happen from falling objects, not building collapse. Securing your space saves lives.

#Do this
1Secure heavy furniture and appliances to walls
2Identify safe spots in each room (under sturdy desk/table)
3Practice Drop-Cover-Hold On drills with family
4Learn how to shut off gas, water, and electricity
5Set up out-of-area emergency contact
6Clear all exit pathways of obstacles
7Strap water heater to wall studs
8Designate a family meeting point outside

During — When the Ground Shakes

You have seconds to act. These steps protect you from the most common injuries.

#Step
1DROP to your hands and knees immediately
2Take COVER under a sturdy desk, table, or against an interior wall
3HOLD ON to your shelter and protect your head and neck
4If in bed, stay there and cover your head with a pillow
5If outdoors, move away from buildings, power lines, and trees
6If driving, pull over safely, set the brake, and stay inside the vehicle
7Do NOT run outside during shaking -- falling debris is the biggest danger
8If trapped, tap on a pipe or wall so rescuers can find you

After — After the Shaking Stops

The first hours after an earthquake are critical. Stay alert and methodical.

#Step
1Check yourself and others for injuries before moving
2If you smell gas, open a window and leave immediately -- do not use switches
3Check for structural damage before moving through the building
4Put on sturdy shoes to protect against broken glass and debris
5Use flashlight, not candles, to check for damage
6Expect aftershocks -- they can occur for days or weeks
7Check on neighbors, especially elderly and those with disabilities
8Listen to emergency broadcasts for instructions
9Do not re-enter damaged buildings
10Take photos of damage for insurance before cleaning up

Questions people ask

What should I do during aftershocks?

Aftershocks follow the same rule as the main quake: Drop, Cover, and Hold On.

  • Get under sturdy furniture or against an interior wall
  • Protect your head and neck
  • Stay away from windows, mirrors, and heavy objects that could fall

Aftershocks can continue for days or weeks after a major earthquake, and some can be almost as strong as the original. Stay alert and keep shoes nearby — broken glass is a common hazard.

How do I check if my home is safe to re-enter?

Before going back inside after an earthquake:

  • Look for visible damage: Cracks in walls or foundation, shifted walls, leaning chimney
  • Check for gas leaks: Smell for gas or listen for hissing. If you detect gas, leave immediately and call your utility company
  • Check water lines: Turn off the main valve if you see leaks
  • Inspect the electrical system: If you see sparks, frayed wires, or smell burning, shut off the main breaker

If the building looks structurally damaged (walls cracked, floors uneven), do NOT enter. Wait for a professional inspection.

What supplies should I keep in an earthquake kit?

A solid earthquake kit should include:

  • Water: 1 gallon per person per day (minimum 3 days)
  • Food: Non-perishable items, manual can opener
  • First aid kit with medications you take daily
  • Flashlight + extra batteries (not candles — gas leak risk)
  • Sturdy shoes by your bed (broken glass is the #1 post-quake injury)
  • Whistle to signal for help if trapped
  • Wrench or pliers to shut off gas and water
  • Phone charger (battery pack)
  • Copies of important documents in a waterproof bag

How do I help someone trapped under debris?

If someone is trapped, your safety comes first.

  • Do NOT enter unstable structures — aftershocks can cause further collapse
  • Call 911 immediately and describe the situation and location
  • If they're conscious, talk to them — hearing a calm voice reduces panic
  • Do NOT move heavy debris unless you're trained — shifting weight can cause further collapse
  • If they're partially accessible, provide water and cover them to prevent shock

Tap on pipes or walls in a pattern of three to help rescuers locate people. If you're trapped yourself, use a whistle or tap rhythmically.

Should I stand in a doorway during a quake?

No — this is a common myth. In modern homes, doorways are no stronger than any other part of the structure. You could also be hit by a swinging door.

Instead: Drop, Cover, and Hold On.

  • Get under a sturdy desk or table
  • If no table is available, crouch against an interior wall, protecting your head and neck
  • Stay away from windows, exterior walls, and anything that could fall on you

The doorway advice dates from old adobe buildings where the door frame was the strongest part. It doesn't apply to modern construction.

Quick facts

  • During an earthquake: Drop, Cover, and Hold On. Don't stand in a doorway — that's a myth.
  • Aftershocks can last days or weeks. Keep shoes nearby — broken glass is the #1 post-quake injury.
  • Before re-entering after a quake, check for gas leaks — smell for gas or listen for hissing.
  • Keep a wrench near your gas meter to shut it off in an emergency.
  • A whistle in your earthquake kit can help rescuers find you if you're trapped.
