Preparing for a Large Earthquake in Southern California
The Risk of a Major Earthquake
The San Andreas fault is one of the most active seismic faults in the world, and it runs directly through Southern California. Scientists estimate that there is a 60% chance of an earthquake measuring magnitude 6.7 or higher occurring on the San Andreas fault within the next 30 years. Such an earthquake would have devastating consequences, causing widespread damage and potentially killing thousands of people.
What to Do Before an Earthquake
There are a number of things you can do to prepare for a large earthquake. These include:
- Creating an emergency plan. This plan should include a list of emergency contacts, a meeting place for your family, and a plan for how you will evacuate your home if necessary.
- Securing your home. This includes bolting down heavy furniture, securing loose objects, and installing earthquake straps on gas appliances.
- Stockpiling emergency supplies. This includes food, water, first-aid kits, and other essential items that you may need in the event of an earthquake.
- Knowing your earthquake evacuation routes. In the event of an earthquake, you may need to evacuate your home. Make sure you know the evacuation routes for your neighborhood and have a plan for how you will get to a safe place.
What to Do During an Earthquake
If an earthquake occurs, the most important thing to do is to stay calm and follow these steps:
- Drop to the ground, take cover under a sturdy table or desk, and hold on until the shaking stops.
- Cover your head and neck with your arms.
- Be aware of your surroundings and be prepared to move if necessary.
- Do not use elevators. If you are in an elevator when an earthquake occurs, immediately stop the elevator and get out.
What to Do After an Earthquake
After an earthquake, it is important to check for injuries and damage. If you or someone you know is injured, call 911 immediately. If you see any damaged buildings or infrastructure, report it to the authorities.
Be prepared for aftershocks. Aftershocks are smaller earthquakes that can occur after a larger earthquake. They can be just as damaging as the main earthquake, so it is important to be prepared for them.
If you have any questions about earthquake preparedness, please contact your local emergency management office.
