What to Do After an Earthquake

Step-by-step guide for what to do immediately after an earthquake: safety checks, aftershocks, gas leaks, damage assessment, and when to return home.

Quick Steps

  1. 1

    Check for injuries

    Assess yourself and those around you. Apply first aid and call emergency services for serious injuries.

  2. 2

    Prepare for aftershocks

    Drop, Cover, and Hold On with each aftershock. They can occur immediately or hours later.

  3. 3

    Check for gas leaks

    Smell for gas. If detected, open windows, leave without using electrical switches, and call the gas company.

  4. 4

    Inspect your building

    Look for structural damage from outside before re-entering. Do not enter if you see major structural issues.

  5. 5

    No open flames

    Use only battery-powered lights until gas lines are confirmed safe.

  6. 6

    Get emergency information

    Use a battery radio or mobile phone to receive official emergency broadcasts.

  7. 7

    Document damage

    Photograph all damage for insurance and disaster assistance claims.

Check Yourself and Others for Injuries

Before moving, check yourself for injuries. Adrenaline can mask pain. Assess others around you. Do not move someone with a suspected neck or spine injury unless they are in immediate danger. Apply first aid if you are trained. Call emergency services for serious injuries.

Expect and Prepare for Aftershocks

Aftershocks follow virtually every significant earthquake and can continue for days, weeks, or months. Some aftershocks may be nearly as strong as the main event. When you feel an aftershock, immediately Drop, Cover, and Hold On. Stay alert and away from damaged structures.

Check for Gas Leaks

If you smell gas, hear a hissing sound, or see a broken gas line, open windows and immediately leave the building without using any electrical switches (including light switches), matches, or anything that could create a spark. Turn off the gas at the main valve if safe to do so, and call the gas company from outside.

Inspect Your Building for Damage

Before re-entering a building, look for structural damage from outside: large cracks in walls or foundation, chimneys that appear shifted or collapsed, stairways or floors that look unstable. If in doubt, do not enter. Wait for official inspection if you see serious damage.

Do Not Use Candles, Matches, or Open Flames

After an earthquake, gas leaks may be present even if you cannot smell them. Do not use open flames for lighting. Use battery-powered flashlights or LED lights. Do not use the stove, furnace, or any gas appliances until a professional has confirmed lines are intact.

Access Emergency Information

Use a battery-powered radio or your mobile phone to access emergency broadcast information. Follow official instructions about road conditions, shelter locations, and water safety. Official sources include local emergency management agencies, USGS (for earthquake data), and your national disaster agency.

Document Damage for Insurance

Once safety is established, photograph or video all visible damage before beginning any cleanup. This documentation is essential for insurance claims and disaster assistance applications. Contact your insurance company as soon as practical.

Be Aware of Tsunami Risk

If you felt a large earthquake near the coast, do not wait for an official warning — immediately move to higher ground. Tsunamis can arrive within minutes. A natural warning sign is the rapid retreat of ocean water from the beach. If you see this, run to high ground immediately.

FAQ

Frequently Asked Questions

Is it safe to go back inside after an earthquake?

Only re-enter a building after inspecting it from the outside for structural damage. Look for large cracks in the foundation or walls, a chimney that appears shifted, or floors that appear unstable. If the building has been red or yellow tagged by inspectors, follow the posted instructions.

When do aftershocks stop after an earthquake?

Aftershock sequences typically follow Omori's Law: the rate of aftershocks decreases as roughly 1/t, where t is time since the main shock. Expect the most aftershocks in the first 24-48 hours, with gradually decreasing frequency over weeks to months. Very large earthquakes can generate aftershocks for years.

Should I run outside if there is a fire after an earthquake?

If a fire starts in your building and you cannot extinguish it immediately with a fire extinguisher, evacuate the building immediately. Close doors as you leave to slow the spread of fire. Do not use elevators. Call emergency services from outside the building.

What if I smell gas after an earthquake?

Leave the building immediately, leaving the door open as you exit. Do not operate light switches or create any sparks. Once outside, call your gas company's emergency line from a mobile phone away from the building. Do not re-enter until the gas company has cleared the property.

When is it safe to return home after a major earthquake?

Wait for local authorities to issue an all-clear. Check for structural damage, gas leaks, and utility hazards before re-entering. If the building has a red or yellow inspection tag, follow the posted restrictions. Be prepared for strong aftershocks that could cause additional damage to weakened structures.
