Stay Safe During an Earthquake
Knowing what to do during an earthquake can mean the difference between life and death. Here’s how to protect yourself and your loved ones when the ground starts shaking.
How to “Drop, Cover, and Hold On”
The most important thing to remember during an earthquake is to drop, cover, and hold on. This simple action protects you from falling debris, which is the most common cause of injury during earthquakes. The Office of Emergency Services offers detailed information on earthquake safety procedures.
First, drop to the ground. Get under a sturdy table or desk if one is nearby. If you can’t find something sturdy, drop to the floor next to an interior wall and curl up. Try to get as low as possible to the ground.
Next, cover your head and neck with your arms. If you’re under a table or desk, hold onto it with one hand and cover your head and neck with the other. If you’re not under something sturdy, cover your head and neck with both arms.
Finally, hold on until the shaking stops. If you’re under a table or desk, hold on to it tightly. If you’re not under something sturdy, stay curled up and cover your head and neck.
Adapt Safety Measures to Different Environments
The “drop, cover, and hold on” method is the best course of action in most situations. However, you may need to adapt your approach depending on your location.
- Outdoors: Move to a clear area away from buildings, power lines, and trees.
- Driving: Pull over to the side of the road and stop. Avoid overpasses, bridges, and power lines. Stay inside your car until the shaking stops. Consult Caltrans Road Conditions for updates after the earthquake.
- Near the beach: Tsunamis are often triggered by earthquakes. If you’re near the coast, move to higher ground immediately after the shaking stops. Heed any tsunami warnings issued by authorities.
Remember, staying calm and reacting quickly are crucial during an earthquake. Practicing these safety measures regularly will help you respond effectively in a real emergency.
What to Do After an Earthquake
After the shaking stops, take a deep breath and assess the situation. The immediate aftermath can be chaotic, but staying calm and following these steps can help protect you and your loved ones.
Check for Injuries
First, check yourself and those around you for injuries. If anyone needs immediate medical attention, administer first aid if you’re trained. Take a first aid class to prepare yourself for emergencies. Only move seriously injured individuals if they are in immediate danger, such as from a fire or collapsing structure. Be aware of potential hazards like broken glass, debris, and downed power lines. If you encounter a small fire and have the training, extinguish it safely. If you smell gas, turn it off at the main valve, but only if you know how to do so safely. If you have any doubts, leave the area immediately and call 911.
Evaluate Home Damage
Once you’ve ensured everyone is safe, inspect your home for damage. Look for cracks in walls, ceilings, and foundations. Check for gas leaks by smelling for that distinctive rotten egg odor and listening for hissing sounds. If you suspect damage to gas, water, or electrical lines, turn them off at the main source. If you smell gas, evacuate the building immediately and contact the gas company or emergency services. Don’t use matches, lighters, or any open flames until you’re certain there are no gas leaks. Learn how to turn off your utilities in advance.
When to Evacuate
Aftershocks can occur after the initial earthquake, so be prepared for additional shaking. If your home is structurally unsound or if authorities issue an evacuation order, leave immediately. Avoid damaged areas and stay away from unstable structures, overpasses, and bridges. Do not re-enter a building until it has been inspected and deemed safe by professionals. Listen to your local radio or television for emergency broadcasts and instructions. Register for AlertSF to receive emergency alerts on your phone. Remember, safety is your top priority in the aftermath of an earthquake.
Create a Family Emergency Plan
A family emergency plan is your roadmap to safety and reunion when an earthquake strikes.
