Earthquake Preparedness

April is Earthquake Preparedness Month, it has been recognized since the April 1906 San Francisco earthquake and continues to be supported by the state assembly urging all Californians and government agencies to engage in education, evaluation of seismic hazards, mitigation, safety activities, and the exchange of information related to earthquake preparedness with other states and nations.
Surprisingly, many Californians don't consider themselves at risk unless they live on or near the line of a well-known fault, such as the San Andreas or Hayward Fault. This misconception leaves millions of Californians unprepared for an earthquake.
Quick Facts:
  • Major earthquakes registering magnitudes between 6.3 and 8.3 have occurred in California every 5.4 years, on average, for the past 200 years.
  • The United States Geological Survey estimates that there is a 90 percent chance that a major earthquake will strike an urban area in California within the next 30 years.
  • The majority of Californians live within 20 miles of a major earthquake fault.
  • Being prepared could save your life!
While California is a world leader in emergency response and recovery capabilities, our responders can't do it alone. It is the responsibility of every individual to take action, get informed, and get actively involved in emergency preparedness.
Below you will find more information on how you can get ready.

Are You Totally Unprepared?

The Ginger Family from San Diego shows us on the video above how despite all their efforts they are still not prepared for an earthquake! How about you? Are you Totally Unprepared?

The “Totally Unprepared” campaign is a year-long collaborative effort between Cal OES, the California Seismic Safety Commission (CSSC) and the California Earthquake Authority (CEA) that is helping Californians better understand their risk of earthquakes and how to prepare for them.

Shake Out!

Three simple words. Three simple actions that could be make a difference in the event of an earthquake. When was the last time you practiced:

It may be only April, but this month is a great reminder to sign up for the biggest drill in the world - The Great Shake Out which is coming up on October 16, 2014. Last year, more than 24 million people globally and nearly ten million in California were able to practice what to do during a quake and improved their preparedness.
Cal OES and The Earthquake Country Alliance are already in the planning stages of this year's earthquake drill. The ShakeOut has become an important annual statewide event, offering an opportunity for individuals and emergency responders to prepare now so they can survive and recover following the next damaging earthquake.

Register now and we invite your family and friends, so together you can be better prepared!

California Earthquake Preparedness Study

In 2008, the California Earthquake Preparedness Survey (CEPS) was conducted by the UCLA School of Public Health and Survey Research Center for the State of California. The objective was to provide baseline data describing how prepared California households are for earthquakes and where they get their information about preparedness and mitigation.
