California Earthquakes: What To Know Before, During and After

No matter where you live in California, there is a risk of considerable damage due to an earthquake. 

Almost every Californian lives within 15 minutes of an active fault line. And many can still recall some of the strongest quakes to hit the state, from the widespread damage caused by the 6.7 magnitude Northridge Earthquake to the building collapses from the Bay Area's Loma Prieta Earthquake.

So, state and federal agencies have a wealth of resources to help residents prepare for the inevitable next quake. Here is what you need to know before during and after the rumbling: 

Emergency Alerts

The State of California is creating a tool that will be able to warn residents seconds before an earthquake strikes. That amount of time can be lifesaving, according to researchers.

The California Earthquake Early Warning Program works with the USGS to get ShakeAlerts sent to residents the moment researchers detect a quake over magnitude 5.0.

As the state works to develop an early warning system for earthquakes. The San Diego Office of Emergency Services will send an earthquake alert to phones in the San Diego County on June 27th at 11 a.m.

The system is still in testing, but once it is rolled out, people with modern wireless devices who are near the epicenter will automatically be alerted; there is no need to register for this system. 

In addition, local municipalities have their own services to warn residents of a quake. For example, San Diego County uses the SD Emergency app and Alert San Diego phone system to warn residents of disasters. 

Before an Earthquake

The best thing you can do is to prepare for an earthquake ahead of time. 

  1. Secure Your Space
    Find items that will easily move during an earthquake. The state says to think about what would tousle if your home was turned on its side and secure those items. 
  2. Create a Disaster Plan
    Some suggestions for your disaster plan include: how you will contact each other and deciding where your family will meet in case of an emergency; and making sure every member of your family knows how to turn the gas and electricity off. More information on disaster plans can be found here
  3. Organize Disaster Supplies
    Your emergency kit should provide enough supplies to last your family three weeks -- food, water, clothing, personal care and other items. Also create a "grab-and-go" bag in case you need to quickly leave your home. Don't forget about supplies for your pets. 
  4. Ease Financial Hardship
    Renters and homeowners should consider getting earthquake insurance and look into ways to increase the stability of your home. Create copies of your IDs and insurance records. Print photocopies of items in your home that will help when you file an insurance claim. 
Carmen Sandiego was introduced to the world in 1985 as a character in a computer game. The character has since appeared in multiple iterations of the game, such as “Where in the U.S. Is Carmen Sandiego?”; "Where in Europe Is Carmen Sandiego?"; “Where in Time Is Carmen Sandiego?” and others. The character also inspired a PBS game show where middle-schoolers won prizes for successfully answering questions about geography, as well as an animated television series, “Where on Earth Is Carmen Sandiego?” Rita Moreno was nominated for three Daytime Emmys for her voice work as Carmen in the latter series. On Thursday, fans found out that Moreno will be voicing the character of Cookie Booker in a few episodes of the new series. Now, the character will feature in a Netflix animated series, voiced by actress Gina Rodriguez<a href="https://www.nbcnews.com/news/latino/young-adults-are-hyped-carmen-sandiego-netflix-series-badass-latina-n958596" class="linkout" target="_blank"> Read More</a>

During an Earthquake

Of course, we all know that when the ground starts shaking to drop, cover and hold on. But what else should you do in the midst of an earthquake? 

If you are in bed when an earthquake strikes, cover your head with a pillow and stay down. If you are outside, crawl towards an open space away from buildings, power lines and trees. 

If you are in need of immediate help, call 911. Contact 211 for less urgent matters. 

Once the temblor stops, evacuate your home. This may be the best chance to prevent further injury in case of an aftershock. Where possible, it may be better to evacuate on foot. 

Seek out an emergency shelter

An earthquake can also trigger a tsunami near the coast. If you're coastal, pay attention to the waves. If the water suddenly pulls away from the shore, a tsunami may be imminent. Search for higher ground. Find out if you are in a tsunami zone here

Lastly, register yourself as "safe and well" so people know you are OK. 

Natural disaster specialist Dr. Pat Abbot and Victor Roosen from the American Red Cross spoke with NBC 7’s Monica Dean about the upcoming Great Shakeout.

After an Earthquake

Start to check on your home, but don't enter until you know it's safe. Check for gas leaks, chemical spills, broken water pipes or damaged electrical wires. 

Use your refrigerated food first and store canned goods for later. It may be hard to access supplies at stores following a quake. 

Contact your insurance company and begin taking photos of the damage. 

In the weeks following the quake, contact state and federal agencies like FEMA to inquire about federal assistance. 

The 5.2-magnitude quake that shook SoCal Friday is a great reminder: if you’re not prepared for an earthquake, it’s time to get prepared. NBC 7’s Megan Tevrizian speaks with Holly Crawford, of San Diego County’s Office of Emergency Services about what you need to know to stay safe in a situation like this.
