Do you remember the last important earthquake in  California? It was so called “Earthquake drought”, An article wrote by Rong Gong, says it’s been 100 years since a major earthquake in California but that could change at some point in the future.

Rong Gong Says: “It has been almost five years since the state experienced a magnitude 6. It took place in Napa Valley. Years early, in 2010, Southern California felt its last big quake magnitude 7.2 with an epicenter centered across the border in the Mexicali area”.

“It’s been several years since a major earthquake in California, and now scientists claim this calm period will come to an end and might result in a catastrophe if people and industries take earthquake hazards lightly”, says in Gong’s investigation.

Gong’s also has stated the need for urgent alerts: “Memories of a truly destructive quake in many urban areas have vanished away. Consider how much quieter California has been in regard to earthquakes of magnitude 6 or greater”.



The following information supports the idea of how many people have not experienced earthquakes in their lifetime:

  • In the last 25 years, there have been 11 such temblors statewide. In the preceding generation, there were 32.
  • In the last quarter-century, there have been three earthquakes that shook California’s 10 southernmost counties. In the prior generation, there were nine, including the Sylmar temblor of 1971 (magnitude 6.6) and Northridge of 1994 (magnitude 6.7).
  • The greater San Francisco Bay Area has been particularly quiet. Since the great 1906 earthquake destroyed much of San Francisco, there have been only three earthquakes of magnitude 6 or greater. But in the 75 years before that catastrophe, there were 14, according to geophysicist Ross Stein.

The last time California has seen an earthquake as powerful as a magnitude 7.8 was in 1857 in Southern California and 1906 for Northern California. No one alive today has the first-hand experience of that kind of quake in the Golden State.

Rong also says: “A sudden jump in how often earthquakes come can make recovery difficult.”

The constant shaking caused a significant impact on people’s mental and social health. “Rates of things akin to PTSD started showing up amongst people,” said Sara McBride, a public information officer for the region’s emergency management agencies between 2006 and 2011. “It’s a constant reminder of that which you have no control over.”

Experts say it’s important that Californians are psychologically prepared for the prospect of a new era of earthquakes.

That means not only having an emergency plan and supplies, said McBride, now a social scientist for the USGS’ Earthquake Early Warning system, but mentally imagining what that will mean — not just putting a flashlight and shoes next to the bed, for instance, but understanding that it will mean dealing with broken glass on the floor and a power outage that may last weeks or more, and planning for how your family will get through it.

“If we accept that there will come a time that the Earth is going to be more active than usual … that this is a natural process going on,” and plotting how you might react, McBride said, “that gives you a sense of psychological preparedness.”

California has the opportunity to be prepared when an earthquake strikes. Earthquake Early Warning systems are now available for business and industries schools.
