What to Do After an Earthquake or Tsunami Alert
When a natural disaster strikes, what you do in the first few minutes matters most. After an earthquake or tsunami alert, your decisions can directly impact your safety. Here’s a clear, step-by-step guide to help you stay safe and make smart choices in a chaotic moment.
1. Stay Calm and Assess Your Surroundings
The first thing to do is breathe and stay focused. If you just experienced an earthquake, check yourself and others for injuries. Look for hazards like broken glass, gas leaks, or damaged structures. Avoid using elevators and be cautious of falling debris if you’re indoors.
2. Be Ready to Evacuate Immediately
If you are near a coastline and receive a tsunami alert, do not wait. Move to higher ground without delay. Tsunamis can arrive within minutes after an earthquake, especially in low-lying coastal areas. Don’t return to the shore until authorities say it’s safe.
3. Avoid Using the Phone Except for Emergencies
Phone lines and cellular networks may be overwhelmed. Use text messages or apps to check in with loved ones. Only make emergency calls if absolutely necessary to leave the system free for critical services.
4. Monitor Emergency Alerts and Updates
Use a battery-powered radio or emergency app to receive official updates. Listen for evacuation orders, shelter locations, or tsunami status. Don’t rely on social media alone—misinformation can spread quickly during disasters.
5. Shut Off Utilities If Needed
If you smell gas, hear a hissing sound, or suspect damage to water or power lines, shut off the utilities at the main switches if it's safe to do so. This helps prevent fire or further damage during aftershocks or flooding.
6. Watch for Aftershocks or Secondary Waves
Earthquakes are often followed by smaller tremors. These aftershocks can still cause structural collapse or landslides. Similarly, tsunamis can arrive in multiple waves—stay alert and do not return to danger zones too early.
7. Help Others If You’re Safe
If you’re uninjured and in a safe location, check on neighbors, especially elderly people or those with disabilities. Offer help if possible, but avoid putting yourself at risk. Community response is often the fastest and most effective aid after a disaster.

Frequently Asked Questions
Should I wait for sirens before evacuating for a tsunami?
No. If you feel a strong earthquake and live near the coast, don’t wait. Head to high ground immediately—even if no sirens sound.
Is it safe to drive after an earthquake?
Drive only if you must evacuate and the roads appear safe. Watch for cracks, downed power lines, or fallen debris. Keep the radio on for updates.
How long should I stay in a safe zone after a tsunami alert?
Stay put until authorities declare the area safe. Tsunami waves can arrive hours apart, and early return can be dangerous.
From what I’ve seen working with emergency prep teams, the people who act quickly and calmly often fare the best. I remember one coastal town where residents practiced tsunami drills every year—when a real alert came, their response was smooth and fast. Preparation truly makes a difference.
