Earthquakes that strike at night are especially dangerous. Limited visibility, disorientation, and broken glass cause many injuries within the first moments after waking. As a disaster specialist, I explain how to prepare before sleep and what to do when an earthquake hits in the dark.
■① Prepare Your Bedroom Before Going to Sleep
Nighttime safety starts before the earthquake:
- Keep a flashlight within arm’s reach
- Place sturdy shoes beside the bed
- Secure furniture and wall-mounted items
- Keep a whistle or phone nearby
Preparation reduces confusion and injury when shaking begins.
■② When Shaking Starts, Stay in Bed and Protect Yourself
If you wake up during shaking:
- Stay in bed if it is safe
- Cover your head and neck with a pillow
- Move away from windows and shelves
- Do not try to run in the dark
Most nighttime injuries happen while people try to stand or walk.
■③ Use Light Carefully After Shaking Stops
Once shaking ends:
- Use a flashlight, not candles
- Watch for broken glass on the floor
- Move slowly and deliberately
- Put on shoes before standing
Darkness hides hazards that can cause serious cuts and falls.
■④ Be Ready for Aftershocks and Power Outages
Night earthquakes are often followed by:
- Aftershocks
- Power failures
- Fire alarms or emergency broadcasts
Keep your emergency kit accessible and stay alert throughout the night.
■⑤ Evacuate Only If Necessary and Do So Carefully
If evacuation is required:
- Follow pre-planned routes
- Avoid stairs cluttered with debris
- Do not use elevators
- Bring essential items only
Leaving a damaged building safely matters more than speed.
■Summary
Earthquake safety at night depends on preparation before sleep and calm action in darkness. Keeping lights, shoes, and protective items close prevents injuries when visibility is limited. Nighttime earthquakes are survivable when preparation turns panic into control.
